Failzero bcg review

by David -

Not worth the money compare to my old psa bcg. It's smoother but still need lube to function right. Only thing I noticed it's easier to clean only. Beside that after 200 Rd I have some issue with the firing pin. I had to take it apart and lube it to make it work again. Just buy a regular bcg and save some money. 3 star for easier cleaning beside that everything about the same. Let's see if it last more than 20k Rd cause my psa bcg is still going strong with no problem. Never even change ring on it also.

rough start

by Ralph -

In the first 500 rounds the gas Key has come loose. I'm pretty disappointed. seems like there may be some QA issues. I was really hoping this was going to be a bullet proof BCG. I do like the coating and the parts seem to be high quality. just seems like a shoddy staking job and a lack of permatex.

Slickest feeling BCG ever!

by Mr. Smith -

I must say this is truly the slickest feeling BCG I’ve ever had. I own other higher end bolt carriers but none as slick as this one. I haven’t taken it to the range yet but I’m really thinking this bolt carrier would function fine without any lubricant at all.

Great BCG but very light stake job on gas key

by Michael Carris

Overall the bcg looks good. No machining marks. Smooth all around. Finish is perfect. Stake job on the gas key is insufficient. I’ll have to pick me up a staking tool and finish it myself. I’ve read this is often times the case with these so I half way expected it.

Perfect

by Thomas

I bought one 4 years ago and have shot it countless times. It literally had ZERO FAILs. It has perfect functionality and looks good, too. As we all know, looks are the only thing that matters and this BCG delivers. (sarc). I'm here purchasing a 2nd, and highly recommend that others do the same.
