Armalite Handguard retaining ring

Call Armalite and get one directly from them. 

As forthe triangle handguard, you’re going to have to measure the distance of the gas block. I seem to remember that the AR10 rifle length was a bit longer than the DPMS model. If that’s the case, you’ll have to find a handguard that length, or come up with some kind of spacer. 

The spacer idea wouldn’t look right with the triangle HG, but you might be able to disguise it with a Magpul MOE-SL HG????

I believe the Armalite AR-10 gas system is .25" longer than the DPMS LR-308 (which, IIRC, is mil-spec AR-15). The only way to make it work is to lengthen the handguard or fab a spacer.

Unless you want to re-barrel to a mid-gas, run a low profile gas block under your triangular handguard, and setup a faux gas block at AR-15 rifle length. But that's a lot of work just for "the look."
