THE ULTIMATE IN LIGHT AND ACCURATE REPLACEMENT BARRELS. ORDER YOUR CUSTOM CARBONSIX AR STYLE RIFLE BARREL. FEATURING MCGOWEN PRECISION RIFLE BARREL BLANKS, CARBONSIX BARRELS ARE FEATHER-LIGHT AND EXTREMELY ACCURATE.
AS WITH ANY RIFLE BARREL, LOTS OF FACTORS COME INTO PLAY. THE TWO MOST CRITICAL ARE LOAD DEVELOPMENT AND THE SHOOTER. WITH PROPER LOAD DEVELOPMENT, CARBONSIX AR BARRELS WILL SHOOT MOA OR BETTER. WHILE WE CANNOT CONTROL THE OTHER FACTOR, THESE BARRELS ARE EXTREMELY ACCURATE.
HOW ACCURATE ARE THEY?
PLEASE CALL OR EMAIL FOR ESTIMATED BARREL WEIGHTS. WE OFFER A WIDE RANGE OF OPTIONS THAT CAN AFFECT THE BARREL'S WEIGHT. IT IS MORE EFFECTIVE TO ESTIMATE THIS KNOWING YOUR INDIVIDUAL BARREL'S SPECS.

Custom Barrel Restocking Fees, Order Changes, & Returns
50% Deposit Option:
If you cancel your order after work has begun on your barrel, your 50% deposit fee will not be refunded. Prepaid shipping costs will be refunded.
Pay-In-Full Option:
If you cancel your order after work has begun on your barrel, you will be refunded 50% of the barrel price, and prepaid shipping costs.
Please note that no refunds are given for reamer rentals or on custom orders.
No Restocking fee will be charged if work has not begun on your barrel.
Order Changes:
If changes are made that require manufacturing to be restarted after work has begun on your order, a 25% fee will be incurred and the estimated completion time frame for that order will start over. Order Changes would include a different twist rate, length, contour, muzzle steel length, shank threading, and shank steel length/OD. The chamber can be changed without restarting production as long as the caliber remains the same.
Repairs/Returns:
If you are having issues, we require that the entire rifle, including the scope, is sent in for inspection. Customers are responsible for shipping costs when sending rifles to us. Everything is needed in our shop in order to inspect your rifle in it's entirety to help determine where an issue might be. If the problems are found to be the result of a faulty barrel, we will correct the issue and cover the costs to return your rifle to you. If the issue is discovered and determined to not be a barrel manufacturing error or flaw, we will consider making the corrections on the rifle to repair any issues. This will be discussed with the customer before any corrective action is taken. Prepayment for the correction is required before this service is started, and customers will be responsible for shipping costs.
I AGREE
I acknowledge that custom barrel builds currently have an estimated lead time of 8-12 weeks. Changes to specifications after order placement may further affect this timeline.
