Strike Industries products are designed by shooting experts for the shooting sportsman.

The Strike Industries Strike Rail is designed to be lightweight and feature rich. This rail offers Picatinny rail sections located at forward and rear positions along the 12-o’clock of the handguard, leaving plenty of space for your favorite sights and accessories. Picatinny along the center has been left out for optimized weight reduction. M-LOK mounting points at the 3, 6, and 9-o’clock positions provide many more locations for gear as well as excellent airflow to keep your rifle running cool.

NOTE: Due to the nature of the anodization process, colors from batch to batch may vary.

Easy Install For A Newbie

I bought this rail when it was full price and despite the fact that it went on sale two days later I was still very happy with my purchase. The rail arrived with a small defect (very small, purely cosmetic) and the guys at Primary Arms worked very well with me. The offered a return, a replacement, or a discount on my next purchase. I chose the discount for my next purchase and I grabbed a comp. The service department is top notch, and the prices on many things here are the best you can find on the internet.

Really good so far.

I wanted to build a 16 inch 300blk upper and stumbled across this 15.5 inch strike rail. I was immediately impressed by its looks and how deceptively light it felt.

Once attached the handguard felt great. It's a medium size diameter and feels very comfortable in the hand, very solid, and stable.

My only complaint has to do with the barrel nut. It seems too thick. I have a pistol length gas system and had to put some downward pressure on the tube to get it to fit. I've never had to do this with other barrel nuts. I'm using an expo arms gas tube, which I've used in the past on other uppers without issue. I haven't had any reliability issues yet but I don't know about the long term.
