We have offered short action custom Proof carbon and stainless barrels for the last two years.  Proof is now going to offer prefit chambered barrels with 5/8x24 threaded muzzles for the Accuracy Internation rifles.  They will be available for the AE, AT, AX308, AW, AX, and AXMC rifles.  With Proof making these barrels in house, the pricing has dropped on the short action barrels.  We will still offer custom barrels for those wanting something that Proof is not offering.

The Proof Research chambered barrels are going to be priced as follows.

All Steel Barrels - $650
AT/AX308/AW/AX (not AXMC) Short Action Carbon Barrels are $1,100
AW/AX (not AXMC) Long Action Carbon Barrels are $1,100
AXMC Large Tenon Carbon Barrels are $1,100
