It is a great cqb gbb setup. Below I put a starter setup that is pretty reasonably priced for a good cqb setup. I say a good cqb setup because in alot of CQB fields you need to switch to a pistol or shotgun (semi auto or single action low fps weapons) in the killhouse areas so this setup lets you only need only one weapon to play.
If you get a 1911 that takes the cheap 1911 mags you can have your whole kit setup :$90 cheap we 1911 (use coupon code on evike 2 mag gun to start with 3 mags), 10 mags at $15 = 150, Chest Rig $20, Pistol triple pouches $10x4=$40, Eye/face Protection $20, Stock with buffer and stock $30, small reddot $25, use normal clothes for cqb arena . So for roughtly $375-$400 a new player can have a really slick cqb loadout (they promo alot of cqb because in California there are alot of cqb places) that is pretty affordable while being competitive and looks sick with the blowback action.
All in all if there was a good place for cqb in south florida (hopefully killhouse will open and be good) this would be a much more useful item.
