Albroswift Posted July 25, 2019 Report Share Posted July 25, 2019 Looking for a 10 in round floating guard and a .75" gass block that clears inside diameter. Lots of options in the 223/556 size, Not finding much for the 308. Need about 1.75"-1.8" ID to clear most of the low pro blocks. Ideas?

Lr-308FUn Posted July 26, 2019 Report Share Posted July 26, 2019 (edited) https://www.acmemachine.com/ar-308-15-super-slim-m-lok-gen-ii-free-float-handguard/ 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. Edited July 26, 2019 by Lr-308FUn Quote Link to comment Share on other sites More sharing options...

blue109 Posted August 1, 2019 Report Share Posted August 1, 2019 PRI is nice but I dont know about 10". I think you can choose carbine, rifle, 14" or 15". OD is 2" I believe. Quote Link to comment Share on other sites More sharing options...
COBrien Posted August 1, 2019 Report Share Posted August 1, 2019 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.

COBrien Posted August 1, 2019 Report Share Posted August 1, 2019 (edited) Having said that... I suppose a guy could pick up a Hogue carbine-length FF tube: https://www.hogueinc.com/ar-15-m-16-carbine-knurled-aluminum-free-float-forend Add a 3" extension: https://www.hogueinc.com/ar-15-m-16-knurled-aluminum-3-oal-3-gun-free-float-forend-extension And order a "AR-10 DPMS" barrel nut: https://www.hogueinc.com/ar-10-dpms-thread-long-free-float-forend-coupler-only Edited August 1, 2019 by COBrien Quote Link to comment Share on other sites More sharing options...
