My custom built grendel part ii

[COLDSTEEL77]

Great looking rig! I'd be very curious to see what kind of velocities you get from a 28" barrel. It might be close to a 260 Rem. out of a carbine length barrel. Keep us posted.

If i remember correctly, last time i put it on the chrony while it was on the old upper it shot 2816 with 123 gr Hornady A Max. I'm going to do some testing with the adjustable gas block and see if that has any effect on velocity.
