With over two decades supplying the parts to build AR rifles, they had the experience to go with the capability and expertise needed. It allowed them to build rifles to high standards that meet the needs of just about any shooter. Based in Winchester, Kentucky, DSC uses only U.S.-made parts.

Its 300 Blackout is a straightforward and capable AR using a new and increasingly popular caliber. Designed with the competitor in mind, the 3GR (3-Gun Rifle) uses components proven in competition like a stainless match grade barrel, Bullseye Muzzle Brake and ACE ARFX stock. For those looking for a self-defense or duty carbine, the ARC meets that need with its 16-inch nitride-coated barrel, ACE SOCOM stock and folding sights. Looking for light weight? Then the Constant Carry (C3) carbine is perfect, weighing in at a mere 5.75 pounds. If you want just the basics, the DS4 is the ticket. It is a capable representation of the original M4 Carbine-style configuration, with quality parts and a reasonable price tag. If precision is in order using the 5.56mm cartridge, there is the MDM (Modern Designated Marksman) and Midnight Dragon.\u00a0 If you are looking for a AR pistol, the Mini Dragon is available in either 300 Blackout or 5.56mm in various barrel lengths. The company also offers a Patrol Carbine designed with the officer in mind and the StarCar, a basic AR that keeps things simple and affordable.<\/p>\n<div id=\"attachment_62899\" style=\"width: 360px\" class=\"wp-caption alignright\"><a href=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/09\/Screen-Shot-2016-09-01-at-10.41.51-AM.png\" target=\"_blank\" class=\"clickTracking\" campaign=\"doublestar-star10-b-custom-grade-308-ar-full-review\" title=\"DoubleStar STAR10-B: Custom-Grade .308 AR\u2014Full Review\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-62899\" title=\"DoubleStar STAR10-B: Custom-Grade .308 AR\u2014Full Review\" class=\"size-medium wp-image-62899\" src=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/09\/Screen-Shot-2016-09-01-at-10.41.51-AM-350x300.png\" alt=\"The author found that the magwell could act as an effective brace for improvised shooting positions.\" width=\"350\" height=\"300\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/09\/Screen-Shot-2016-09-01-at-10.41.51-AM-350x300.png 350w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/09\/Screen-Shot-2016-09-01-at-10.41.51-AM-150x128.png 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/09\/Screen-Shot-2016-09-01-at-10.41.51-AM-768x657.png 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/09\/Screen-Shot-2016-09-01-at-10.41.51-AM.png 993w\" sizes=\"(max-width: 350px) 100vw, 350px\" \/><\/a><p id=\"caption-attachment-62899\" class=\"wp-caption-text\">The author found that the magwell could act as an effective brace for improvised shooting positions.<\/p><\/div>\n<h2><strong>SPECS<\/strong><\/h2>\n<ul>\n<li><strong>Chambering<\/strong>: .308\/7.62x51mm<\/li>\n<li><strong>Barrel<\/strong>: 18 inches<\/li>\n<li><strong>OA Length<\/strong>: 41 inches<\/li>\n<li><strong>Weight<\/strong>: 9.8 pounds<\/li>\n<li><strong>Sights<\/strong>: Continuous top rail<\/li>\n<li><strong>Stock<\/strong>: ACE Hammer<\/li>\n<li><strong>Action<\/strong>: Direct gas impingement<\/li>\n<li><strong>Finish<\/strong>: Matte black<\/li>\n<li><strong>Capacity<\/strong>: 20+1<\/li>\n<li><strong>MSRP<\/strong>: $2,566<\/li>\n<\/ul>\n<p>How for those that want to step up in power?

The upper receiver houses an 18-inch Wilson air-gauged stainless steel barrel using a 1:11.25 twist rate. It\u2019s capped with a Bullseye Muzzle Brake designed for ultimate muzzle control. Fluted and free floated, the barrel uses a rifle-length direct impingement gas system with a low-profile gas block. Samson\u2019s 15-inch Evolution handguard covers the barrel, providing ample mounting positions for rails of various lengths. The bolt carrier has been NIB-X (Nickel Boron) coated for ease of cleaning and enhanced operation under adverse conditions.

An Ergo Grip provides control along with an oversized triggerguard. Unique to the design is an extended\/enhanced magwell. Longer than a standard magwell, it is heavily checkered for use against barricades, or for a strong hand hold when necessary. A lip at the bottom locks the lower into place on obstacles. ACE\u2019s Hammer buttstock and seven-position buffer tube are installed, one of the strongest on the market. Both are machined from heat-treated aircraft aluminum. Five spring-loaded ball bearings make operation smooth, while etching on the tube provides easily visible position markings. Locking in place, the adjustable cheekpiece can be installed in three different positions to facilitate scope use and allow operation of the charging handle. Angled at the bottom, the stock provides solid purchase for bags or packs for rear support.

Blast was manageable for the shooter but pretty oppressive if you are next to it, but that\u2019s life with a muzzle brake. It provides excellent muzzle control, with minimal rise and very little side-to-side movement. Little blast was extended either up or down, so shooting from prone was not unpleasant. Shooting in close quarters was, as usual with a brake, distracting at best.<\/p>\n<p>Brass ejection was consistent with no failures to eject using several types of ammunition. Along with accuracy testing, several magazine fulls were fired using my \u201cbucket of ammo\u201d consisting of various .308 ammunition separated by bullet weight. Most is FMJ, brands vary along with velocity, but it is all factory new. Shooting steel at 400 yards, it was consistent with all bullet weights from 147 to 175 grains. In most cases the 1:11.25 twist rate works best with 155- to 168-grain bullets, and the STAR10-B followed the model.<\/p>\n<div id=\"attachment_62883\" style=\"width: 210px\" class=\"wp-caption alignleft\"><a href=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/09\/Aquilla-Group.jpg\" target=\"_blank\" class=\"clickTracking\" campaign=\"doublestar-star10-b-custom-grade-308-ar-full-review\" title=\"DoubleStar STAR10-B: Custom-Grade .308 AR\u2014Full Review\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-62883\" title=\"DoubleStar STAR10-B: Custom-Grade .308 AR\u2014Full Review\" class=\"size-medium wp-image-62883\" src=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/09\/Aquilla-Group-200x300.jpg\" alt=\"Accuracy testing with Aguilas's 150-grain FMJ was consistent at between an inch and an inch and half.\" width=\"200\" height=\"300\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/09\/Aquilla-Group-200x300.jpg 200w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/09\/Aquilla-Group-100x150.jpg 100w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/09\/Aquilla-Group-768x1151.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/09\/Aquilla-Group-684x1024.jpg 684w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/09\/Aquilla-Group.jpg 801w\" sizes=\"(max-width: 200px) 100vw, 200px\" \/><\/a><p id=\"caption-attachment-62883\" class=\"wp-caption-text\">Accuracy testing with Aguilas&#8217;s 150-grain FMJ was consistent at between an inch and an inch and half.<\/p><\/div>\n<p>Several magazines were used including Gen2 and Gen3 PMAGS in 20- and 30-round capacities. DPMS magazines were tested in 10- and 20-round versions along with Brownells&#8217; Mil-Spec 20 rounder\u2019s, Lancer Systems, and Larue Tactical versions. All of them inserted and worked fine, although the 10-round DPMS magazine is completely covered by the magwell. They eject just fine, but you will not be able to grasp them at all; in fact you need to push them in place from the bottom. Not an issue for most, but if your world limits you to ten you are going to want a pinned long magazine. All others cycled well, inserted easily and ejected properly. My Larue magazines were the tightest fit, followed by the Lancers. The PMAGS were the loosest.<\/p>\n<p>As one might expect, the Hammer stock is very solid, locked into place nicely, was easy to adjust and stayed in place. The cheekpiece was easy to adjust and could be reversed if needed. Tightening the screws on either side kept it in place throughout testing. Just remember, you cannot clear the charging handle unless it is fully extended. Threaded holes sit along the stock that could be used for sling studs or other threaded additions. ACE also sells buttpads of various lengths.<\/p>\n<a href=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/09\/Screen-Shot-2016-09-01-at-10.25.03-AM.png\" target=\"_blank\" class=\"clickTracking\" campaign=\"doublestar-star10-b-custom-grade-308-ar-full-review\" title=\"DoubleStar STAR10-B: Custom-Grade .308 AR\u2014Full Review\"><img loading=\"lazy\" decoding=\"async\" title=\"DoubleStar STAR10-B: Custom-Grade .308 AR\u2014Full Review\" class=\"aligncenter size-full wp-image-62894\" src=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/09\/Screen-Shot-2016-09-01-at-10.25.03-AM.png\" alt=\"Screen Shot 2016-09-01 at 10.25.03 AM\" width=\"948\" height=\"282\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/09\/Screen-Shot-2016-09-01-at-10.25.03-AM.png 948w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/09\/Screen-Shot-2016-09-01-at-10.25.03-AM-150x45.png 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/09\/Screen-Shot-2016-09-01-at-10.25.03-AM-400x119.png 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/09\/Screen-Shot-2016-09-01-at-10.25.03-AM-768x228.png 768w\" sizes=\"(max-width: 948px) 100vw, 948px\" \/><\/a>\n<p>DSC\u2019a extended magwell proved solid while working on and around the bench, on barricades and a stack of railroad ties on the range. It was possible to really lock it down, especially on wide and flat surfaces. Heavy checkering on the front digs into wood or similar surfaces. Placed on top of a bag or pack, it sits solidly as well.\u00a0 If you find yourself grasping the front of the magwell for some reason, it provides a nice hand hold. Not the best hold for stability, but it\u2019s all you have at times and this makes for a solid purchase. Put on some gloves and it really locks into place.<\/p>\n<h2><strong>Final Thoughts<\/strong><\/h2>\n<div id=\"attachment_62896\" style=\"width: 410px\" class=\"wp-caption alignright\"><a href=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/09\/Stock.jpg\" target=\"_blank\" class=\"clickTracking\" campaign=\"doublestar-star10-b-custom-grade-308-ar-full-review\" title=\"DoubleStar STAR10-B: Custom-Grade .308 AR\u2014Full Review\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-62896\" title=\"DoubleStar STAR10-B: Custom-Grade .308 AR\u2014Full Review\" class=\"size-medium wp-image-62896\" src=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/09\/Stock-400x290.jpg\" alt=\"ACE\u2019s Hammer buttstock and seven-position buffer tube are installed.

Five spring-loaded ball bearings make operation of it smooth.<\/p><\/div>\n<p>Using CMC\u2019s trigger adds to the capability of the rifle. My preference remains a two stage, and they offer one if so desired. This trigger was predictable and reliable with no light primer strikes experienced including on some mil-spec primers. Nor did it come loose during testing.<\/p>\n<p>During ten-round, rapid-fire strings, especially at range, the barrel did get hot pretty quickly, resulting in some vertical dispersion at range. I found myself changing my hold on target at 500 yards to stay on steel for the last few rounds. It did not present itself during group shooting where time between shots was more normal.<\/p>\n<p>Weight and balance on the STAR10-B is excellent, with the balance point right at the front of the magwell. Fluting the barrel keeps things light and the contour is not too large. It was pleasant to work with around the barricades, outside the muzzle blast. In my experience 18 inches is about right if you are looking for close quarters work with the .308\/7.62x51mm, and this rifle was no exception.<\/p>\n<p>[one_half]<\/p>\n<div id=\"attachment_62891\" style=\"width: 410px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/09\/Samson-Hand-Guard.jpg\" target=\"_blank\" class=\"clickTracking\" campaign=\"doublestar-star10-b-custom-grade-308-ar-full-review\" title=\"DoubleStar STAR10-B: Custom-Grade .308 AR\u2014Full Review\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-62891\" title=\"DoubleStar STAR10-B: Custom-Grade .308 AR\u2014Full Review\" class=\"size-medium wp-image-62891\" src=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/09\/Samson-Hand-Guard-400x267.jpg\" alt=\"Samson\u2019s 15-inch Evolution handguard covers the barrel, providing ample mounting positions for rails of various lengths. \" width=\"400\" height=\"267\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/09\/Samson-Hand-Guard-400x267.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/09\/Samson-Hand-Guard-150x100.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/09\/Samson-Hand-Guard-768x513.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/09\/Samson-Hand-Guard-1024x684.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/09\/Samson-Hand-Guard.jpg 1200w\" sizes=\"(max-width: 400px) 100vw, 400px\" \/><\/a><p id=\"caption-attachment-62891\" class=\"wp-caption-text\">Samson\u2019s 15-inch Evolution handguard covers the barrel, providing ample mounting positions for rails of various lengths.<\/p><\/div>\n<p>[\/one_half]<\/p>\n<p>[one_half_last]<\/p>\n<div id=\"attachment_62888\" style=\"width: 410px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/09\/Break-1.jpg\" target=\"_blank\" class=\"clickTracking\" campaign=\"doublestar-star10-b-custom-grade-308-ar-full-review\" title=\"DoubleStar STAR10-B: Custom-Grade .308 AR\u2014Full Review\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-62888\" title=\"DoubleStar STAR10-B: Custom-Grade .308 AR\u2014Full Review\" class=\"size-medium wp-image-62888\" src=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/09\/Break-1-400x264.jpg\" alt=\"A Bullseye Muzzle Brake caps off the 18-inch stainless Wilson air gauged and fluted barrel.\" width=\"400\" height=\"264\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/09\/Break-1-400x264.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/09\/Break-1-150x99.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/09\/Break-1-768x508.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/09\/Break-1-1024x677.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/09\/Break-1.jpg 1200w\" sizes=\"(max-width: 400px) 100vw, 400px\" \/><\/a><p id=\"caption-attachment-62888\" class=\"wp-caption-text\">A Bullseye Muzzle Brake caps off the 18-inch stainless Wilson air gauged and fluted barrel.<\/p><\/div>\n<p>[\/one_half_last]<\/p>\n<p>All in all, the STAR10-B was very accurate, reliable and handy to run on the range and in and around barricades and other obstacles.
