2 New Grendel Builds - 16" Hunting Rig & 10.5" Pistol

[ToedrAg]

Those look great!

Did you bed the barrels into the uppers?

That pistol is going to have massive concussion without a can.

I did a thermo-fit into the BCM Upper on the 16". The BCM uppers really are great for that reason and that seemed to work well.

The Aero upper on the 10.5" had a pretty perfect fit with the Lilja barrel extension without shimming (no movement at all), but I kept going back and forth whether to shim/thermo-fit or bed with loctite. In the end, I decided to bed the 10.5" with Loctite 680 after lapping the upper receiver (see pic)



And yes, I know the shorter-barreled Grendel with a brake is going to be crazy loud - my Dominus can't get here soon enough! Let me know if you can hear the shorty from your house LRRPF52!
