Exactly what I was looking for in a lightweight carrier. Amazing quality and finish to go along with a great design. Thank you Sharps!

Have Low Mass BCG in my Mark12 Mod0(Clone) and it is smooth. Only fired a few rounds through, but I am happy so far! Time will tell. Going to buy .224V bolt and throw it in my other Mk12. Love SRC products!!

After a 500 round practice day with quick fire up shoot. The bolt just wiped clean and look like never shot.

Corrected a short stroking of the bolt carrier group without adding to increased recoil if I had used a lighter spring or buffer. Cycles great now, and maintained the tight groups I was getting before. Well worth it.

So far I'm impressed. While this isn't the lightest BCG on the market, the S7 tool steel and enhanced features are well worth the reflected price. The DLC coating is insanely easy to clean carbon off. Don't purchase this BCG to try to lighten up you're AR15. This is designed to soften the recoil impulse and with a standard carbine spring and 3.6 oz buffer weight this shot incredibly soft. An adjustable gas block or gas key is definitely recommended and once you dial in the gas to where it cycles, the results are an extremely low pulse, minimal recoil, soft shooting AR15. If you compare this to other lightweight BCGs the Sharps lightweight XPB BCG is on par with some of the more inexpensive options while being one of the most durable. Great product Sharps.
