These uppers are configured for the active shooter to be able to move faster and shoot longer than with a conventional AR platform upper.

Adams Arms proprietary .625 pencil barrels are the lightest on the market. They are Melonited inside and out for the highest corrosion resistance available.

The Melonite ads accuracy comparable to a stainless steel barrel and a true bore that does not have the inconsistencies and tolerance build up of hard chrome.

Based on our testing this barrel will outlast hard chrome doubling the life of the barrel.

Available in both the mid and the carbine length gas systems, these upper utilize the patented Adams Arms short stroke gas piston system along with the new lighter low profile gas block. The block's design removes approximately 1 ounce of weight from the front of the AR to compliment the lighter barrel and Samson Evolution rail system.

The Adams Arms piston system in these uppers is the same proven product that goes out to all of our customers.

Each upper is complete with a one piece bolt carrier group, charging handle and Adams Arms Gas Piston System with the 3 position adjustable gas block installed and ready to go!

This is the first .625 gas piston upper and is the lightest gas piston upper on the market today. Weighing approximately 4.2 lbs you save almost a pound when compared to a similar tactical product. The lighter weight means faster movement and less work to carry it all day.

Each Ultra Lite Evo Upper will come with 2 2" attachable rails, 1 4" attachable rail, and the Adams Arms Comp. With the Adams Arms Comp attached your rifle will have virtually no muzzle rise so not only will it be quicker on target but it will stay on target better f or follow up shots.
