Round hand guard/gass blocks


Recommended Posts


I have this on my LR-308 & I am using a Aero Precision low profile gas block & it fit's fine. The diameter is 1.39" I have a .750" gas block on my midlength 16" BCA 416 r stainless barrel. Not a issue with it at all they also carry this in the 10" your looking for.  

Here's mine on my rifle current setup. 

I forgot to note, that the Acme Machine rails are nice quality for the price. They are DPMS pattern high profile, perfect for the Aero Precision M5 Uppper & Lower.

I can't recall seeing a "plain old" free-float tube in a 10" length for a large frame rifle.

Carbine-length? Check.
12"? Check.
15"+? Check.

I've got a "Fulton Armory" (Young's Manufacturing...) 12" FF tube on my LR-308T, over an SLR Sentry 7 adjustable GAS block, carbine-length gas system. Works quite well, IMO.

Having said that...

I suppose a guy could pick up a Hogue carbine-length FF tube:

Add a 3" extension:

And order a "AR-10 DPMS" barrel nut:
