5:25 laughs with my gibbz g4 left handed upper
And…. If your into a single shot rifle, there is a BCG that doesn't let the exhaust gas hit you in the face. Beleive it or not the newer upper receiver by BCA does exactly that. I purchased one and very pleased with it. It my reloading go to in an AR platform.
Where do we find the files for the demo parts?
I just redid our pcc ar. Was using a adj gas block from CMMG until it blew apart. Believe it was a quality ctrl issue cause we have an 8" barrel n they use them in their 6" barrels with no issue. I just ended up switching gas tube out, a new slotted bcg from Griffin, h3 buffer n switched out trigger with stage 2 match grade with slotted raptor se charging handle. The bcg with the slots in it to redirect gas has made a huge difference with blowback. Great vid! Thank u
I like the fact you guys are using footage from a demonstration video that you didnt make but ok…
l have really gotten fond of AT3, their products and how they do business
it's beautiful.
When building a rifle, invest in a good barrel, BCG and trigger. The rest is all pretty much equal.
I was hoping to hear more about piston driven or delayed blowback BCGs as well.
Great review, thanks!
PAMAX tactical and the X Slick BCG has been my go to for a long time. especially as a reloader and ladder walking serious spicey rounds.. now PAMAx has this new Magnetic Buffer system.. keep your eye out for this new fangled system!
Anytime C.J makes a video I watch it. Dude literally could explain guns to a monkey and they would understand it.
Timely. Thanks
What does it mean when the lugs on the bolt are sharp on the rear after about 500rds
