hang guard to cover SigSaurer SRD762Ti silencer

Having tired to waiting for Sig to actually produce and sell the backordered (for months/years now) MCX 9" 300 Blackout barrels and silencer sized hand guard, I have embarked on a AR15 build project. I'd like to use the Sig SRD762Ti silencer still, but at 1.75" in diameter I am having problems finding a hand guard that would fit over at least the base of the silencer once I get my stamp back from the ATF and purchase a 9-10" 300 Blackout barrel for a SBR.

Still trying to decide on a 16-18" barrel in either 5.56 NATO or 300 Blackout to have something to shoot while waiting so I am thinking a 12-14" hand guard that would eventually cover the first few inches of suppressor when mounted on the SBR.

Does anybody know of a decent looking hand guard with a ID > 1.75"?

Also, what is the what sort of gap should I target between the silencer and the hand guard? don't want to have something so close I can't hold the rifle.

Sorry this is long, been trolling for a while but new to the forum and build project thing.

Tharkun2279, welcome to the Forum. The only thing I could suggest is one of the old 2" OD handguards like the Yankee Hill Customizable Free-Float tubes, and they are probably 1.75" ID. Have someone with a lathe, turn the inside larger where the suppressor would ride, to give it at least .030" clearance. They were made in 7-9/16", 9-5/8", and 12-1/2" lengths. Or get your self a Yankee Hill Machine Barrel nut, and Jam nut, and find someone to thread some thick wall 6061 aluminum tubing, and make it to your specs.

Welcome to Sig Talk!! Have couple thoughts for your AR build plan. I too like my support hand extended out on our ARs. It's the same hold regardless of the barrel lenght. So, have rifle length hand guards (12 to 13") on all our ARs, including this 10" suppressed SIG 516 SBR. This Lancer hand guard has bout 1/8" to 3/8"s clearance with the SOCOM556-RC can.

This 5.56/223 setup isn't a gang-banger as she heats up after 50 or 60rds. Nothing damaged, just too hot to hold with continous fire and a bear hand. She's fine on our typical 2 or 3 mag range trips too. This is our home defense rifle, and we really don't need a high round count gun for that duty.





Your 2 stamp 300Blk 9" SBR build will take a lot of patience - perhaps more than you'd expect.

My ATF Form 1 for 9" MCX 300Blk SBR filed in April '16 took almost 6 months, and the SRD762Ti's Form 4 also filed in April remains in process. 9 months is my expectation for this suppressor's stamp, and I don't think ATF's processing schedule is getting faster...

Like yourself, we're VERY annoyed with SIG mgmt's decision to delay these MCX 300 barrels, hand guards, etc - But at this point, SIG's delivery schedule may not be your build's critical path.

So, if you like/want SIG AR's piston system rifle, starting with an available 16" MCX in 5.56 may get you to your 300 SBR build on a similar schedule as any other...

Cheers

Thanks both of you for the input. The search goes on.

It's early in the build process, I expect it to take several months as I am still largely in a planning/research phase. It may turn out to be a couple lower receivers and 2-4 uppers to get everything I am thinking about, including a high precision option and multiple calibers, so the wait for the ATF will toddle along while I progress. The first lower receiver is on the way so I can get the serial number and start the paperwork/wait.

Sounds like you have an ambitious armory develop plan working there. Wish ya success!

Wouldn't suggest waiting too long on those ATF stamp submittals. We can't know what the next federal admin will do, but 'things' could be a lot different soon after that Januray '17 inauguration....

Cheers
