I just got a Armalite AR10A4 (20"brl) and am interested in upgrading the upper. I spoke with a company who told me that they can make an upper in any caliber that is spawned off of the .308. Any help in what calibes this would be would be appericated.
Thanks

I have chambered AR-10s in 300 WSM, 6.5 WSM, 6.5 SAM, .308 WIN., 308 win. IMP., .243 IMP., 22-250 IMP., 6 mm. IMP.,
and 6 BR.

Basically, anything that will function less than 2.830" OAL. and will use a boltface between .480" and .540" will probably be workable.

My reamer has a 40 degree shoulder, and about .012" taper with a .334" neck.

Nightforce has great tracking capabilities, they are rugged, a bunch of elevation, holds zero forever, and reticles are designed for long range shooting. So if you are looking to shoot long distances constantly, then you need a scope that can take the abuse. -- gilmillan1

Nightforce is such a solid combo of reticle, available elevation, glass that is good enough to shoot at the longest range you can dial. Nightforce has bullet proof construction that can handle the incidental horse rolling or some other rodeo action. -- bigngreen


Nightforce ATACR Scope Review

The new NightForce ATACR is for sure a top choice for any long range shooter. Read More


The total package. Nightforce is the best I have used as far as turret feel and solid detents. I have never had one that didn't track right on and always return to zero. Nightforce NXS is the best value for everything I need. -- Broz
