14.5” M4A1 Block II Clone 556

$921.00

The US Military has proven the durability of the heavy quad rail. It is great for high round counts that heat up the carbine. Everything has a compromise. I believe the extra weight of the quad rail helps keep the barrel cooler for a longer period of time. Who does not love modularity? The picatinny rail makes it easy to mount flashlights, night vision equipment and other tools. This upper is an absolute vibe that needs to be in your duty rota􏰀on.
