arwoodie Posted June 28, 2021 Report Share Posted June 28, 2021 If I wanted to leave the delta ring + handguard setup in place on a flat top upper with a DPMS low profile, would AR15 handguards (with top rail) line up with the receiver? I've looked at some measurements that seem close, but I don't know if it's close enough. Quote Link to comment Share on other sites More sharing options...

See if Midwest Industries has a DPMS-Low setup. Look for the MRF rail, or other drop-ins from them. I have an MRF from 10 years ago, and it's stout, solid, and nice.

blue109 Posted June 30, 2021 Report Share Posted June 30, 2021 DPMS low is the same height over bore as milspec AR15. that was the reason they switched standards...so AR15 irons and FSGBs would work on the LR308s. What I don't know is if the delta ring is the same. I'd assume not since the 308 chamber area is thicker than it's pee shooting counterpart.

beantown Posted February 6, 2022 Report Share Posted February 6, 2022 This is a UTG AR15 Slim drop in handguard on my DPMS LR308. And it is SLIM! Does not rotate or wobble one bit. It's very solid. Oh, and hey guys, long time no see! Quote Link to comment Share on other sites More sharing options...
