GStephen Posted January 8, 2023 Report Share Posted January 8, 2023 I put a new low profile handguard on my dpms 308 upper. The adjustable gas block just barely clears the inside of the upper. I would guess about .025” on each side. How much actual clearance is required? Or am I going to get a block that clears more? Quote Link to comment Share on other sites More sharing options...
GStephen Posted January 8, 2023 Author Report Share Posted January 8, 2023 I might add, it’s a 16” mid length heavy barrel and 12” handguard. I wouldn’t expect a lot of movement. But I don’t know. Quote Link to comment Share on other sites More sharing options...
DNP Posted January 8, 2023 Report Share Posted January 8, 2023 I don’t know that you’ll have an issue, but you could shoot it a bit and see what you think. A little off each side with a dremel would create a little more clearance if needed. Quote Link to comment Share on other sites More sharing options...
sketch Posted January 9, 2023 Report Share Posted January 9, 2023 I ran into this problem with a .458 socom build , gb was actually touching. I ran a file down the inside of the hg instead of the gb. ^^^ shoot first and tune it if needed. Considering breaking in and ammo grade for optimal performance 🍻 Quote Link to comment Share on other sites More sharing options...
