I have about 5 AR lowers laying around waiting for a build. One will be a deer/antelope gun for my wife.
What cals are somewhat easy builds on the AR-15 platform. I have 223, 300 Whisper, and 6.5 Grendel. I'm not a fan of the 6.8SPC or the various 45 cals. I could be talked into a WSSM cal of 25 or bigger, but only 1. I might do another Grendel for my wife - unless you guys can give me a better idea. I'm not doing any more 223's.
Wildcats don't frighten me, I just don't want to do 16 steps to get brass formed.

Some is Good---More is Better----Too Much is Just Right
