I actually am fairly happy with my.......... UTG.
It is durable, it is strong, it was dirt cheap ($70), and I am as embarrassed to admit it as riding a moped (I don't!). But I have banged on it with a 3# dead blow hammer and it took it. I have used it with a grip and light just fine. As far as the guys who say it might fail when you need it- its not a pro gun! Its a hobby/garden/HD gun that if ever used to save my ass, it would probably only be once. The chances of it just breaking are slim, and much slimmer when SHTF is in progress. As far as that goes, a rag can serve as a hand guard if need be.
I should also mention that its ugly, heavy, and ChiCom shit! But I get a pass on the last one because I ONLY buy vehicles, new or used from the big three (unlike many with American Quadrails and who will begin flaming me shortly). I also am suffering from paycutitis, and this is the reason I settled for the Ugly Turn Gun rail, until the DD lite is doable (going with rifle length and chopped FSB).
Ok, let the burn begin!
