I can do it here in SNellville depending upon what Handguard you have
If RedX cannot do it, I have an NSR wrench as well and am a certified armorer. You would just have to ship it to me after reviewing that the components ordered are compatible with each other -> gas block journal sizes, gas tube/system length, gas block OD vs rail ID, muzzle device vs barrel threads, requirements of shim kits or not, etc...
Can I just say - not OG, but been here awhile - that I've noticed over time that these two ODT'ers always seem very knowledgeable about AR's and SO WILLING to help out fellow ODT'ers when it comes to stuff like this.
Well done REDX and @Wallace's, well done!
You guys both really embody what ODT is really about in my mind!
