Working on my first ever Grendel build. Building the upper first so I can swap it with a current lower I have for now until I can save again to build a new one.
Barrel: Lilja AR 24" fluted
Upper: Vltor Mur
Bolt carrier group: Underground Tactical Type II
Gas Tube: Rifle length from Underground Tactical
Still haven't decided what hand guard, flash suppressor and gas block I want to use yet. I'm open to suggestions. Want to go with a lighter weight hand guard to make up for some of the weight of the barrel.
