AR10 308 upper and parts package

Description

Really nice package here. These are excess to my use.

I build AR as a hobby these days (trained gunsmith). I go thru all the critical measurements on this and fix or replace parts as needed.

This upper has a 16” ballistics advantage barrel on it. It has been bedded and torqued to specs.

I have bore scoped the barrel and verified the gas port is lined up and that the throat, lands, grooves and muzzle all look good.

Feed ramps and chamber have been polished for smooth feeding and reliability.

Bolt installed is brand new nickel boron coated trybe

Upper and handguard are AERO.

adjustable gas block installed but not tuned yet.

Test fired for function and accuracy with soft points and m80 ball. Photos are of the 16” groups

Second barrel
Is a 12” KAK I think. Bolt is also a trybe nickel boron coated
12” is also polished feed ramp and chamber and has been crowned. Second bolt has titanium firing pin installed and headspaces to that barrel ok. I shot this 12” combo some and it was reliable but I wanted a lighter barrel and low mass bolt. Comes with spare firing pin and gas block.
