Spike's Tactical .22 LR AR-15 conversion kit

I listed this used only because I have had it a while, and may not have all the paperwork it originally came with. This unit has never been fired in my rifle. It did come with residue from a test fire at the factory, but I cleaned that up with some CLP. I mounted the kit to make sure it fit my AR-15 and then placed it back in it's tube. I got three extra BlackDog Machine magazines when I got the kit (26 round capacity I think), so there are four total magazines included with this sale. I got them in black, not smoke, to match the rifle better. I had loaded them once to make sure they functioned okay, but again, they have not been used to fire and are like new. There is also an extra spring and a gas tube plug included(if you want to keep it even cleaner when firing in bulk). There are also two o-rings on the chamber insert to keep the fouling down when firing a lot of .22 ammo. Please ask any questions by email:
