The Hodge Defense Systems Spine Lock 10.75” M-LOK AR-15 Handguard prioritizes strength and stability. Its design refines the Pinch Lock system, adding material to the “spine” for improved rigidity. This M-LOK compatible handguard is machined from 6061-T6 aluminum with a Type III hard coat anodization. It utilizes the same trusted barrel nut as Hodge’s Wedgelock and Pinch Lock rails for easy installation.

This rail to quote It’s Always Sunny – “It’s tighter than dick skin” well done Hodge team, not to thick (Knights) not too thin (BCM). It’s a really nice balance.

Hodge and Big Tex are the best in business! Incredibly fast shipping and quality rail.

Hodge and Big Tex are the best of the best. The S-Lock rail is essentially a slimmer P-lock, and is close in profile to the Wedgelock. Like all Hodge stuff, the S-lock is fantastic. An excellent blend of rigidity, aesthetics, durability, and overall design. Grab one if you can.

I’m not the most experienced LARPer out there, but this is one of the nicest rails I’ve put my hands on.
Finish 10/10 – it literally couldn’t get better.
Feel 10/10 – a cross between the chonky plok and the wedge. It’s slimmer but not to the point it feels like you’re grabbing a hot dog.
Weight 10/10 – it’s not lightweight, but it’s super well balanced which is the main reason for high marks. Most of the weight is concentrated near the barrel extension. My scale read about 1.5 oz lighter than the plok.
I think this is a true do-all rail.
