Hey guys, building a few more rifles and wanted a little advise! Anybody used Del-Ton's kits? are they worthy? Anything to watch out for with them, and anybody know of another company that sells customizable kits like this? Any advise would be great!

Also curious on twist rates for 16" barrels. I mostly shoot military 55-62grain ammo. What would the advantages be of a 1/7" or a 1/9" twist be in comparison to each other? Which is better with mil-spec ammo? what are other popular bullet grain weights to use in each of the twists?

Thanks again!
