survivalshop Posted May 15, 2019 Report Share Posted May 15, 2019 It looks different & has a weight in the BC Body & has a special coating to limit friction . Also notice, one staked Screw for attachment, maybe its dovetailed in or something also . Who's first to buy & test one of these ? https://www.brownells.com/rifle-parts/bolt-parts/bolt-carrier-groups/m16-optimized-bolt-carrier-group-mpi-black-sku152000263-128171-230452.aspx?trk_msg=SAPET29O4IK497O7BC2PAULFB4&trk_contact=2JJJVUF1UDMRTL1H7DD8FULMM0&trk_module=bna&trk_sid=AJSKRHH1FEU30LK6IOQF7R2A4O&utm_source=listrak&utm_medium=email&utm_term=CHECK+IT+OUT&utm_campaign=Browse-Abandonment&utm_content=Product-Browse-Message-1 Quote Link to comment Share on other sites More sharing options...

jtallen83 Posted May 15, 2019 Report Share Posted May 15, 2019 I want one, maybe in a few years when the price comes down a bit or someone else is making a cheaper version. Quote Link to comment Share on other sites More sharing options...

You could drop the Surefire in any standard AR and increase reliability, to a point, It's made for working weapons. The low mass stuff requires adjustable gas blocks and special spring and buffer system to be reliable, and even then I wouldn't use them for a duty type weapon.

He didn't ask anyone if they had one - he knew what he was doing... Surefire announced this awhile ago. https://www.surefire.com/optimized-bolt-carrier-group-556mm.html Quote Invented by Jim Sullivan, one of the original designers of the M16, the SureFire Optimized Bolt Carrier (OBC) is designed to improve the functionality of an M4/M16/AR variant weapon system during both unsuppressed and suppressed firing. This patented design makes numerous improvements to the standard Mil-Spec full-auto bolt carrier group which allows more time for reliable feeding of ammunition from the magazine, nearly eliminating bolt-over-base malfunctions. The OBC also delays unlocking of the bolt during the firing sequence, which allows expanding gases more time to exit the bore, in turn reducing back-pressure gases exiting the upper receiver group. Additionally, the neutrally balanced counterweight improves carrier and barrel extension lock-up, nearly eliminating bolt bounce. The OBC also reduces felt recoil, allowing for better tracking of sights and more control of the weapon when firing. Coated with an advanced anti-friction coating, the OBC resists friction during use and makes cleaning easy. For the ultimate in reliability, choose the SureFire OBC. This is the same principle as adding a heavy buffer - or heavier buffer - Surefire just put the weight in the BCG body. Pistol Caliber Carbine BCGs have been doing this for years. When Surefire announced this, it's the exact information that I want to use as an example for a certain "budget .308AR manufacturer" as to why their buffer weight is all fucked up... They (fanbois included) want to argue with me about it - then I'll just direct them towards Surefire, so they can tell Surefire how fucked up they are, in their own feeble-mind logic.
