BCM RAIDER M-13 Rail

[jackblack73]

This small channel seems to have the first video and closest look yet at this new rail that I could find. Some smart stuff going on while still being pretty light: double wall for rigidity; 3-6-9 pic rail at front; cable pass through.

Looks like they literally copied a Geissele Mk4

Pretty nice looking. I'd love to check out the upper receiver more than the rail. Nice that they put the pic rails in all the critical positions.. like a
Geissele in that sense.

What makes it rated for machine gun fire? It appears to be a M4 profile barrel.

NYH1.

The guy says how light the upper is, but then says it's machine gun/hard use? Not sure which claims are his and which ones are BCM's actual goals in the unit.

I'll give him a B in an attempt to do a video on an item he isn't overly familiar with, the scores go downhill quickly from there.

It’s not easy to make anything truly original with ARs, but I thought the double walls and pass throughs were pretty innovative.

If I was looking at Mlok, I'd look hard at this.

literally the only things they share in common is that they are made of aluminum alloy, have a separate barrel nut, and have both Pic and MLok. They didn’t copy anything whatsoever from Geissele. No one does, because there is no reason to.

Pretty good question, though the M4 profile barrel is itself rated for automatic fire. Just not hamfisted hosing. What’s interesting here is that they appear to be trying to address the heat problem that occurs when someone actually shoots a gun much with a super skinny MLok rail. It’s been convenient to ignore that problem because a nice feeling skinny rail that can be C-clamped is popular. And a 1.375” ID/ ~1.5” OD MLOK rail happens to be the most convenient shape to manufacture and doesn’t require barrel nut timing.

Hey, Stick, are they going to be doing these without the side pic rails (but keeping the bottom and top as is), or in quad format? I don’t dig the stepped transition. Although probably not a problem once I put a LAM on top.

I’d be pretty interested in one of these in a ~11”-11.5” length. BCM does do 12.5” barrels, so perhaps they have an interest in building a rail around one.
