[Chasing Durability - G&P WOC GBBr's]

I created a video outlining both the HPA stuff and the charging handle mods a while back. Here it is for all of your video viewing pleasure

Yes that is high pressure air, the magazines are drilled and tapped to accept air quick disconnect fittings. With the dual regulator set ups at 145 psi and the npas dialed in, right arround 400 w/ .20 gram bb's but it has some pretty impressive recoil!

You will have to forgive my reply if it isn't clear as I am typing this on my phone. I'm not sure I can recommend one brand of bolt carrier over another as my experience is limited to G&P carriers, an AABB carrier, two element steel carriers and my prime... so far I would not reccomend the element carriers, ever. The prime is great, but I've had to sand mine a lot to get it to function correctly in my WOC.

 

Charging handles is hard to say. I have two real ones, a DPMS (low end) and a Noveske (high end) and physically there isn't a dang difference between the two. I think the DPMS is cheaper by a few dollars and functions identically to the Noveske.
