RTB Complete Lightweight Bolt Carrier Group - Black Nitride

Featuring our new Right To Bear Lightweight BCG, weighing in at approximately 8.9 Ounces, or 252.5 Grams for you lightweight build fanatics! Using our low mass Bolt Carrier Group creates less reciprocating mass moving back and forth inside the action, which reduces recoil significantly. Our lightweight carrier also allows proper cycling with less gas. When used in conjunction with an adjustable gas block & a reduced power buffer spring, you can tune the gas way down, which will reduce muzzle rise and carbon build up.

The increased lubricity from the Black Nitride process allows you to take full advantage of its lightweight profile. The slick surface combined with our lightweight carrier, creates very little resistance and allows the rifle to cycle smoother and increases reliability.

Unbelievable deal! June 30, 2017
Reviewer: G. Gibson from Maryland  
This BCG is identical to my Rubber City Armory BCG that I paid $250 + s+h.  The only difference is my RCA BCG has everything  nitride coated including the firing pin using H&M's proprietary  Blacknitride. The RTB BCG is slightly less glossy  and appears not to be using H&M's  Blacknitride coating.  A good review of  nitriding is  "Finishing Touches" by Steve Adelmann. I weighed  the RCA and RTB and both came in at 260 grams,  which is fantastic because I can use the same gas setting for both.  Highly recommend!

noticeably light April 10, 2017
Reviewer: steve p from coppell, TX United States  
this thing is lighter than a standard BCG with no Bolt or guts! by leaps and bounds. Unfired currently but hoping it cycles as nice as I think it will
