This handguard series will not let you down.
If you're looking for a quality USA made handguard for your AR-15, the NEW SXT Series Handguards are what you need. These rugged free-floating handguards offer a 7-Sided M-LOK® attachment system, ambidextrous integrated QD sling point, a sleek chamfered leading edge and comes with a 2" M-LOK® attachment.
Easy to install – the simple clamping system uses two cross bolts which fit into the barrel nut for a rapid and easy installation. (The old SXS Series clamping system used a bias block on the bottom to secure the forearm to the barrel nut—which required knurling).
Standard SXT Series Handguards are available in lengths of 4”, 7”, 9”, 10”, 11”, 12” and 15” (See Specifications tab for actual lengths).
Includes: Hex wrench, barrel nut, and barrel nut wrench

Sig Tread Direct Swap
Location:
Date: Apr54l 10, 2024
This Handguard uses the same barrel nut as the Sig Tread, making this one of the only direct swap options available. Despite being the only option, I would say this is the best option. It upgrades the look, function, and operability. It decreases the weight and heat build up. It increases options with M-lok and Rail, and adds two extra sling points. This is worth every penny.

I bought this for my CA compliant sig m400 cuz the stock handguards awful, it fits WITHOUT NEEDING TO SWAP THE BARREL NUT so dont waste your time. Just take off stock handguard then slip sxt on and tighten the screws. The barrel nuts are identical on my specific AR cant speak for all AR’s. Very happy with the sxt handguard, highly recommend over stock sig m400 handguard.

Outstanding SIG M400 Option!

I bought the SXT to put on my M400 TREAD. The TREAD is notorious for being difficult to upgrade, but the SXT handguard was a perfect fit! The installation was simple and the guard fits seamlessly. The SXT eliminates the basic shortcoming of the stock Sig handguard, which requires a small Picatinny rail to mount backup iron sights. That places the front and rear sights on different planes…but with the SXT the sights now sit completely in line. The Samson works with the existing barrel nut (although the package comes with a nut and the wrench to install it) and installation took less than 5 minutes. The side screws and the bottom set screw make a very secure fit.
Samson customer service was very responsive when I emailed a question (less than 12 hours to respond) and the product is outstanding in fit and finish. I also appreciate that the Samson logo is discrete - unlike other brands that turn the handguard into a bill board advertisement.
I will be buying more Samson products in the future — but this is the best M400 upgrade I have found!

Improved barrel nut attachment point making the handguard free floating. Attachment screws are on the side making access easier for assembling/disassembling of the rail. I love my Samson Mfg rails and have them on every rifle.
