SKU: PARALLAX-308-P3R-17.5 Categories: ,


The FFSSR is a sleek, one-piece handguard that offers one of the slimmest profiles available on the market (1.50″), plus outstanding versatility for attaching your choice of accessories. Built-in, full-length top Picatinny rail provides plenty of versatility in mounting optics and sights, while four limited-rotation QD push button sling swivel mounts let you position the sling where it’s most comfortable for you. M-LOK Compatible also!

The P3R rail is built on Parallax’s proven AR-15 Free Float Super Slim Rail (FFSSR) design, and features slight changes to account for the heavier needs of .308 rifle systems. The .308 Rail utilizes internal ribs to strengthen and add rigidity to the rail, and is mounting using an scaled-up barrel nut system similar to that of the FFSSR.

This 308 rail system is strong enough to handle the rigors of duty rifle use, while it is also one of the thinnest and most ergonomic rail systems available for 7.62 NATO AR style rifles. Their design features a thin, rail-free section in the center of the rail that improves ergonomics.

Barrel Nut uses a 1 3/8″ crowfoot Wrench (NOT INCLUDED) , All hardware and Shims included

    Great product

  5. Daniel L. (verified owner)

    It fits well with the M5 Aero receiver set and looks and feels great, but the barrel nut requires to be timed to have the upper rail match with the upper receiver rail. A difficult way to install. The black color is also a shade lighter than the receiver.

    Great products. My orders either come in early or the date expected.

    I used this Handguard on for a .308 Ar10 build using a Aero Precision upper and lower. The Mat black color is a bit different between the two manufactures but not to much that it looks clashing. I really like the design as I was looking for something different and a bit uncommon. (make sure you order the crows foot barrel nut wrench as it does NOT come with the handguard so I had to track one down from a different vendor. I would have rather paid a few $ more to have it come with the handguard than trying to track one down after the fact. As a minor improvement, add anti-rotation tabs on the bottom side of the rail. Over all I really like this product and design! looking forward to may next purchase.

    I have purchased two of these so far. Both have been well made with a nice finish and have had zero fitment issues when paired with Aero M 5 uppers. I ordered several parts from BK and I have received them fast and always correct.

  13. Alexander Sharpe (verified owner)

    Surprising light and very tough.

  14. Shannon K. (verified owner)

    Light weight, sturdy and a great price!

  15. Jason S. (verified owner)
