Largest Inside Diameter Handguard for AR 10?

[LRShooter101]

I am looking for the largest Internal Diameter freefloat handguard that I can get for a build using an AR 10/DPMS receiver?

I would prefer something that allows the modular attachment of rails (not looking for just a round tube).

I want to make sure that I have plenty of clearance between the barrel components and the handguard to prevent any possible contact when the barrel whips. The last AR10 that I had would string really bad as the barrel heated, and it looks like it was due to the gas block hitting the handguard as the barrel moved more & more with heating.

I would love to put a Seekins Precision SP3R on it, but they do not make a version for the DPMS AR 10 receiver.

Any help would be greatly appreciated. Thanks!

Apex Machine a possibility. Have three, allow more than adequate clearance for SLR GB’s on .850/.936 GB shoulders, lots of accessory pic rail options, bolt on full length top rail, hi/lo options. They are round, textured for good grip. Solid mount platform, though not a Seekins or E1 Aero.

Search for suppressor handguards as these are typically designed to fit cans inside the guard and have more clearance than most.

Might be worth it to swap out the receiver to one that uses AR15 style handguards so you can use the Seekins rails. The round one is huge, I have one on a 300BLK and it clears a 1.5” diameter can by quite a bit.

Not sure if it's the largest but certainly enough to accommodate most cans (slide over my Sig SDR762 with ease).

1.72" inside diameter (from barrel nut cut to forward end) fits most muzzle devices and 1.5" suppressors

Not sure about the exact inside diameter, but i have one of these and it seems much bigger than your typical ar15 handguard. They are the old mega monolithic receivers/handguards. JSE surplus still has some in stock in both keymod and mlok.

this is what I used on my heavy barrel AR, 1.8 inch inside diameter

JP's round handguard and Odin Works are what I've found and use. 1.75" ID which is the biggest your gonna find.

Thanks to everyone very much for the feedback! I have some very good options to look at now.
