Decent
Bought this BCG for a lightweight AR I'm putting together and while it's a solid build and a good weight the coating is worthless. I have yet to fire a single round with it and have only cycled the action a few times after installing and lubricating the BCG but the coating is already worn off in a spot on the gas key.
Build tip
I am building a 5 lb max weight ar. The nickel boron bcg is priced great for a newby My issue was a tight fit in the buffer tube. I measured the back end and it was a bit larger than the other bolts, i put in a different ar and no problem. I have a new buffer to try the brownells bolt carrier group out. I read that this is common with building your own ars. But the rear part is larger than standard bolts.
Looks cool but coating is terrible
It looks nice but after no more than 100 rds it has worn the coating off the bottom. Make sure you clean the bolt VERY good b4 storage and leave it dry. The finish on the bolt head wore off and now has some pitting after a couple weeks in storage
Decent, finish wears too easily
I've been running this BCG for around a month and a half now. The finish is a cool color, but it just wears too easily. I've had about 50 rounds through my rifle using it, and there are two VERY distinct lines where the brass casings rub against the carrier. These lines have gone through the TiN finish and are already exposing bare steel. The cam pin has also already had around half of the overall finish worn off, but that's normal. Outside of that it's decent at best. Definitely an upgrade from the nitride BCG, but not something I'd put in my competition build.
not all GOLD glitters
The machining and plating looks great. but occasionally it doesn't fully closed either during FIRing, cycling manually or loading a round using bolt release or charging handle. maybe the plating is too thick?, the bolt doesn't moved smoothly inside the carrier. Compared it with Faxon LW BCG, what a big difference on the TRAVEL of the BCG onto the upper. will try swapping the bolt from my other BCG. Would still recommend this because of the price, but don't get too much excited, maybe a few upgrades and mods are needed.
Good, but had issues
I bought this BCG for a lightweight budget build. It fit the bill and got my rifle under 5lbs and under $800. Works good, but had an issue with the bolt itself. Originally I was getting failures to extract no matter where the gas was adjusted too. Switched to a known good BCG and the problem went away. I disassembled the extractor and took off the o-ring around the extractor spring and that helped get it extracting. Then after about 150 rounds when the gun warmed up it would start failing to extract again. Switch to a known good BCG and the problem went away. I ended up keeping the Brownells carrier and buying another bolt and now the BCG functions as it should, but at 150% of the cost. Overall, I would not buy this again.
