I commissioned a 16" Centurion Recce 5.56 barrel using a Bartlein factory blank in 2019ish.
Barrel specs:
16" Recce profile, mk12 chamber for mk262 ammo
Bartlein 5R blank
1:7" Twist
Mid-length gas system
Pinned Centurion gas block w/tongue and groove
Melonite gas tube
I also had a headspaced bolt and Centurion carrier.
Ultimately built out for a friend with Centurion upper, CMR 12.5" rail, BCM charging handle and a Forward Controls Design 6315 flash hider.
It has 240-270 max round count on the barrel/bolt (500 max on the upper).
Upper was hastily krylon'd to match his lower. This upper has sat stagnant in his safe for 5 years and now it's back in my hands...and the last thing I need is another 5.56 gun/upper.
Asking $895 for the complete upper
