Adams Arms Evo Lightweight Upper 1

The proprietary .625 Pencil barrels are the lightest on the market.  They are Melonited inside and out for the highest corrosion resistance available.  The Melonite also allows for accuracy comparable to a stainless steel barrel and a true bore without having the inconsistencies and tolerance build up of hard chrome.  It is going to outlast any chrome lined barrel on the market.

Adams Arms Evo Lightweight Upper 2

Available in both mid length and carbine length gas systems, these upper utilize the patented Adams arms 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.

The new Samson Evolution rail series on these uppers is a completely modular design.  Using a tubular base and top picatinny rail, there are multiple options for attachments to the rail.  With options like picatinny rails in both 2” and 4” lengths to QD swivel mounts to even an additional 4” rail extension that will mount in front of the gas block you will have a fore end that you can truely make work for you the way you want it.

Adams Arms Evo Lightweight Upper 3

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 to a comparable tactical product.  The lighter weight means faster movement and less work to carry it all day.
