Twin 12.5” Riflespeed complete uppers recently shipped to a customer. Each has its Gas Control cross-pinned to the barrel for the ultimate in rugged installation. CMT DRT 10.5 handguards offer an excellent forend at a great price. They look kick ass, too.

@riflespeed how's the clearance eon the Geissele rails? I see you have a picture of one, is there room in there or is it close to hitting the rail? I'd really like to run your gas control but I don't want to give up my rail for it.

Fit great. We have several images of different uppers with Geissele handguards on our upper pages. Check out the OD Green Mk4 on the 11.5” page for a particularly sexy build. Thanks.

I’m wondering about a sbr upper.
@riflespeed

10.3” is not possible, is it?
9.5” rail?
.308 16” rifle gas


Add: I’m extremely happy with that build. Smooooth and the rear gas, I swear, improved.
I shot the M4A1 (fsb Colt model) and definitely noticed some gas suppressed.
I did not notice gas from the .308. Idk if RS has anything to do with it, my nose
is my data lots of laughs. I wanted space between the can and adjustment. They get hot.

Great looking rifle!

You can run the RS7524 on a 10.3" carbibe with 9.5" barrel but you will need to run a space that is no larger than the barrel to push the muzzle device out just enough to clear the gas control. Depending on the muzzle device and suppressor, you may have issues since the gas control ends flush with the barrel threads. The RS7524 is perfect for a 10.5" carbine gas barrel with a 9.5" handguard.
