McMillan A3-5 Stock Project

How important is the stock to rifle accuracy?

Starting with a new out of the box Remington 700 SPS in 308 Win., which comes with a plastic molded stock, I ran several groups using Federal Gold Medal Match 168 grain SMK ammo. Groups were all over 1 MOA with most 1.5″ to 2″ at 100 yards.

I then had McMillan Fiberglass Stocks of Arizona install one of their A3-5 adjustable stocks. No other changes were made to the factory action, barrel or trigger. The result was consistent 0.5″ groups with the same factory Federal GMM ammo.
