Buy Now:
Piston conversion kit keeps your M4 carbine running cleaner and longer. Piston systems are cleaner on the operating system because the hot dirty gases are expelled near the gas block instead of inside the upper receiver. Piston kit replaces the front-sight base, handguard cap, handguards and bolt carrier on your stock upper. Piston is hard-chrome plated and is removable from the front of the gas block, and the bolt carrier includes an impingement key for maximum strength. Works on semi-auto carbines only, with 14.5″ barrels or longer, and includes assembly instructions. Some gunsmithing required.

California gun laws suck

2. Has anybody tested in in really dirty harsh conditions?
1. Why do they display it in fully auto when the fine print says semi only
Nice Backstop !
You should be Proud !
I felt a great disturbance in the Force, as if millions of closed-bolts cried out in terror, and were suddenly melted.

@C172Pilotdude The kit includes the one piece carrier that has the full auto profile. We are currently out of stock on this item.
Sheva needs one of these…
ahh, so they are built, by themselves then. Makes sense. I thought they were just a shop that did the piston kit and happen to have a bunch of these full auto lowers laying around ^_^. My mistake.
pretty sure those are m16a1 or m4a1 lower's and then just ar-15 uppers. As they do full auto, and would require someone to have a lower built previously to 1986. I'm sure any of those lower's that these guys have on these ar's are worth more than 5g's a pop :-/ Wish they'd just retract the ban of 1986 so that we can all purchase fun stuff like this, for cheap. Now if you had an actual ar-15 built prev to 1986, you can convert it, but need paperwork, etc… CLass III Title, etc etc…
LOL HOLY SHYT!
