Lower Kit
Quick shipping. Good price. I like the lower kit the parts are grouped together in separate plastic bags. Make them easier to identify.

my go to LPK's
I like these LPK's CMMG does a good job, parts are always consistent. I don't do fancy-pants triggers, at 5'11" and 180 pounds I think I should be able to pull a mil-spec trigger without wiggling the rifle and I like these triggers.
