Bought one of these NiB BCGs from 762 Industries and I'm not happy at all with it.
Received it, cleaned it, lubed it, and set out to the range. The BCG would consistently fail to load the following round after firing. 1 Boom then 1 Click. I considered myself LUCKY if it was just a FTF since it frequently jammed & chewed up a round.
New mags or old proven mags made no difference...same result. Also wouldn't lock back after firing the last round.
I opened her up a few times to work on the rifle while on the line to whistles by the range crew. I even changed out buffer springs to see if that made any difference (nope).
Took 300 rounds to the range and ended up firing 30~ with almost as many chewed up and ruined. Great day huh?
Not happy at all with the one I received and have already spent the money on a Centurian phosphate to replace it.
anyone use one of these yet? Even better if someone can compare to rguns nib bcg.
I haven't tried an rguns nib bcg but I bought one of these shortly after purchasing one of their 308 BCG's and it's pretty good quality. I would recommend.
don't know anything about Nickel BCG's will they work in any standard AR?
West Fork Armory has similar NIB for $125, full auto version. Just so you know. I bought one, but I am still into my first build.
