"So far so good!

I've had this for about a month and a half now and I've had no issues, it chronos right around 330-340 with green gas at my indoor field (will be different depending on temp). Build Quality feels fine, a little stock wobble but nothing terrible, and some minor handguard wobble, but I chalk that up to the delta-ring system, and that should go away when I switch to a free float system.

The inner barrel does not extend all the way to the end of the outer barrel, though that was likely designed that way to keep FPS down, and I've run into no issues yet as a result of this.

I have tried both GHK (m4 & mk12) and Matrix m4 magazines and both feed with no problem. In theory every WA spec m4 mag should be a plug and play replacement. The Golden Eagle magazine that it came with did start leaking, even after o-ring replacement, I was able to get that exchanged through customer service.

I'd definitely recommend this! Especially if it will be your first GBB

"Want to start off with I love shooting it, it's so fun a little heavier than I thought no problem though I could use the muscle build anyway, pretty realistic compared to ones I shot in the past and I do want to say on full auto I did have a lil jam the chamber slide got stuck half way and sprayed all the the green Gass out of the mag and the only complaint I have is I can't tell which way is up or down on the hop-up besides that it's really good

"This M16 is so realistic kind of heavy though so you'll need some strong arms to carry this thing for a few hours of gameplay, hits hard and sounds so good, and if you are looking for compatible mags any western arms will do (Matrix, Golden Eagle, King Arms, S&T, G&P WOC, 6mm)
