7 or 8 twist .308 win

[dick]

Spook, has been commissioned for the barrel build. 16", 8 twist, stainless, carbine gas system, for DPMS LR-308. The plan is to make it cycle with out help, I will be using an adjustable gas system to regulate the full power ammo.

Nitriding chrome-moly results in even more corrosion and erosion resistance than stainless but without the accuracy-robbing layer of chrome plating. Stainless is not better than nitrided chrome moly steel, and AAC barrels are match grade. Also, AAC barrels are engineered to a drawing based on having the actual Remington 700 action drawings, and with the threads that are compatible with sound suppressors. If I said who makes them, our competitors would make a beeline for the same company and skip years of expensive testing I had to do to find who was best.

Do you make em for a Savage pre-fit?

Any idea if I could get a shorter barrel with that same profile like a 6 or 7in?
Obviously it wouldn't work with the group buy or??

Thanks,
Mike

ETA, how much to get it nitrided?

I should add, that is a LOT cheaper than the Shilen bbl I put on my Savage.
