.458 SOCOM Bolt Carrier Group
« on: April 11, 2011, 11:37:34 PM »

what exactly makes it different...is it JUST the bolt face? Are all other parts standard ar15 such as the kotter pin, the firing, pin, etc?

(Please move this to the proper forum section if it isn't already, for better exposure).

Just the bolt face and extractor.  Everything else is standard 5.56.  To make a .458 SOCOM bolt you recut the bolt face and reshape the extractor.  Done, but not as simple as it sounds, is it Marty?

Doing the bolt is not the hard part.  The extractor - that is where I spend all my time...  shape, put in bolt, test, remove, adjust, test, adjust, test, polish, test, refinish...  I got to where I was able to get them at the first try but you need a 7.62x39 extractor as starting material.  Starting with a .223 extractor is a lost cause.

thanks guys. so hey marty, i think i posted in another thread but it relates here...if i sent in the whole bcg to get nickel boron coated, would that effect the extractor (or anything else) in any way, because of the coating to consider? i'm wondering if i'd have to tell them not to touch that part or if they know or can nickel boron coat everything (except the firing pin i imagine?)?

No, actually the NiB coating will make the extractor slick and could make feeding nice and smooth.  My own personal rig has a full FailZero BCG in it.

Does KCJ do small order coatings (single complete BCG for example), or would it have to be a larger run?

Also, what are your thoughts on having this done to a piston (not necessarily just an AR piston)?

KCJ said to contact WMD Guns for the plating work.  WMD Guns will do a bolt carrier group with the hammer for $100.00.  Here's their web address and they have a price list on it.
