Description

The SR-15 E3 MOD 2 series’ 5.56mm NATO barrel is manufactured for military grade durability, and is free-floated inside a URX4 M-LOK handguard. Included in this upper is Knight's new E3.2 bolt. Dual ejectors ensure clean and consistent ejection even when a traditional high-backpressure suppressor is used. Refined Lug geometry and optimized material selection ensures lug durability in excess of even the industry-leading KAC E3 bolt. A viton o-ring prevents extractor vibration and lift, and a hard chrome exterior simplifies cleaning and maintenance. The 5.56mm 3-Prong Flash Eliminator interferes with propellant gas combustion forward of the muzzle to significantly reduce flash signature, will not ring upon firing or when struck, and is compatible with the Knight’s line of 5.56mm QDC Signature Reduction Devices.

KAC SR15

Published by Jason S on Mar 21st 2023

These guys had an SR15 upper in stock, need I say more? Not only did they have it but they shipped it the same day and got it to me before I could even get my hands on a lower, optic, trigger, and the rest of my build. This baby is going on ADAC lower and will be super sexy when complete. Thanks FTC! Will certainly look your way for future purchases.

Best of the best

Published by A.M. on Dec 14th 2022

This upper is the most rock solid Iâ€™ve ever seen. The flash hider is amazing and I love the fact that this came with a buffer. This was on my door step three days after I ordered it. Freedom trading will be getting my business again. Especially once the KAC SR-15 IWS Lower comes back in stock.
