KAC pic's?

Will it be possible for the rail to cover a lo pro gas block? I'm not sure but from the description that F2S gave it sounds to me that you won't be able to have the rail overhang the gas block if you have to first install the urx4 then install the gas block. Or am I just crazy?
If this is an obvious answer that I am missing then my apologies.

You're just crazy bro. But that's ok.

I mostly finalized my build so I guess I'll be waiting in line for the release. Now just need to figure out the muzzle device. Keep flirting with a 5.56 MAMS, but will likely end up with a BCM BCMGUNFIGHTER Compensator MOD 0-5.56(perm attached

) and find a BCG.

Sorry I missed this.
It is made to allow a low-profile gasblock to fit under the rail.
You do, however, need to use a set-screw GB, which can be tightened through the keymod holes in the 6:00 of the rail, whereas it is nigh impossible to drive taper pins through.

Or difficult

Imaging Jack, Casey and I all twisting and bending something to get it to fit, and we only got one in...

There is a method to our madness please be patient.

Jack/Kevin,

Could you guys provide exact ID demensions for the URX4? I've got a 1.5" suppressor (Ops Inc M4S) that will only stick into the rail about a half inch if I go with the 10" rail...wondering how close I'm getting?

Also, can you guys provide weights for the rails? Especially the 8.5" and 10" models?

Much appreciated.
