I know I am not the only one but man I got the itch to build another upper. WOA 20" varmint barrel is calling my name. I know I should learn my 16" WOA spr upper but man those velocities are calling to me lol. Anyone own one other the TR Mlok handgaurds that use there special barrel nut wrench thats 50$. I know you can you a strap wrench for but it almost seems a Geissele wrench might work with some mods to it. Maybe after a few neat pours of eagle rare . will say the hell with it and complete the purchase.
