Pardon my ignorance, but what exactly does this do?
It enables you to pull back the bolt assembly in an AR15. This particular handle is beefier than a regular one and has an extension on the left to facilitate operation when you have a scope mounted above it.
Those extended handles aren't near as sturdy as what the BCM has. You can tear the "ears" off the handle with one handed charges. The BCM is strong enough where you don't have to worry about that.
Great explanation here:
Bravo Company MFG President Paul Buffoni set out to develop a fix for a weak link in the M16 family, and that weak link is a tiny roll pin that you use every time you charge your weapon.
Modern training doctrine has most of us working the charging handle with our support hand while the primary hand stays on the pistol grip of the weapon.l Initially, the weapon was designed for the shooter to grasp the charging handle with their firing hand, and to pull directly to the rear.l This straight back method reduced the stress on the charging handle roll pin, but takes us out of a firing position.
Most troops (MIL or LEO) are using the flat of their support hand, or side of their index finger off their support hand to pull back on the charging handle while pushing forward with their firing hand on the pistol grip.l This creates a very positive action for loading or clearing malfunction clearances.l The down side is increased wear on the charging handle, with most of the charging handle roll pin taking the brunt of the abuse.
Bravo Company MFG teamed up with Vltor Weapon Systems to develop and manufacturer a unit that would create a stronger charging handle which would take the stress off the roll pin and redistribute it throughout the latch and body.l Secondly, the latch was designed to keep the force inside the latch to prevent lateral pressure on the charging handle and receiver, resulting in smoother overall operation.
ACTUALLY, it was, then it went back down and I ordered one. Prices fluctuate.
You guys should try reading time stamps of posts before you show off to your friends :clue: (note to self; always remember why I don't post to slick deals, just snipe all the deals - cause its full of people who are clueless!)
Just bought the 5.56/.223 mod 4 Medium for $39.06 shipped this morning. Very pleased as I've been watching it for a while so thanks OP. I really hope the medium works for me, I was between that and a small. My LGS sells this for $60 even so I'm sure I could recoup my cost if the medium is too big. Now to find a nice upper and BCG....
