Criterion-SS 1-8 Twist Varmint Upper, A4


Our Varmint Upper comes with a Criterion 20″ Barrel, complete bolt assembly and charging handle. You have your choice of barrel type and length, threaded or non threaded muzzle(does not come with muzzle device), finish and flutes. If you have a muzzle device you would like to use you may ship it to us for installation at no additional cost.

This Upper has been designed for long range accuracy. It’s built on a A4 receiver with a 10 MOA extended scope rail. This gives you a great mounting surface for your scope with proper eye relief. It also gives you and easy way to remove the scope and reinstall it without losing your zeros.

For the Varmint Uppers we use Match grade barrels with a 2″ round aluminum free float handguard with two studs in front; one for a bipod and one for a sling.
