Please note: all 12H, 15H, and 15L have been upgraded to a 7-side M-LOK® handguard with integrated steel QD, chamfered leading edge and 2" picatinny rail. The 12L profile is still our old design and does not come with integrated QD and 2" picatinny rail at this time.
Do you shoot a .308 rifle? Bigger calibers shouldn't require bigger rails. For .308/7.62 rifleowners looking for a fast-handling, easy to grasp accessory rail, the Samson SXS-762 Series free-floating M-LOK® system is the perfect AR.308 upgrade. Its sleek profile creates a comfortable feel to a wide range of shooters, regardless of your application. The SXS system creates a solid extension of the upper receiver with the benefits of rapid and easy installation thanks to the pre-installed, captured clamping system and Samson barrel nut.

How do I know what SXS-762 Profile (height) to choose?
There are two standard heights of .308 AR receivers on the market, Armalite/DPMS High, and DPMS low. The DPMS Low is not the same as the DPMS GII. To be sure you are choosing the correct Samson handguard for your AR10 style rifle, you can call the manufacturer of the receiver or measure from the center of the bore to the top of the receiver.
If it is approximately 1.32â€, this is Armalite/DPMS high and you will need the SX-7.62H series. If it is roughly 1.25†it is DPMS low and you will need the SXS-7.62L series.
Measuring the height from the center of the bore to the top
of the receiver: To Measure the distance from the center of the bore to
the top of the receiver you will need a set of calipers. Measure the
diameter of the threads and divide that number by 2. Then measure from
the bottom of the threads to the top of the rail on the receiver. Use that result and subtract the divided number; which is the height from the center of the bore to the top of the receiver.

Great handguard that matched to the Aero M5 (DMPS-high) upper receiver with no drama. I try to support products made in NH.
Shipping was fast, and it was nice to get order & tracking details emailed in real-time.
