Description
The TEKKO Free Float 10" M-LOK rail from Mission First Tactical is built for guys who want their AR to look and feel like one solid unit instead of a barrel wrapped in a plastic shell. This is a free float design, meaning the handguard rides on the barrel nut and never touches the barrel itself, so nothing you do with a sling, bipod, or forward grip transfers pressure downrange and messes with your point of impact. The monolithic top rail ties directly into the receiver rail with zero gap, giving you one continuous sight plane if you are running a long optic or back-up irons out toward the muzzle.
MFT machines this rail from 6061 aluminum and finishes it in a Type III hard coat anodize, so it shrugs off scrapes, rust, and the kind of abuse that comes with actually using your rifle instead of babying it. M-LOK slots run the full length at the traditional 3, 6, and 9 o'clock positions, plus MFT added extra offset mounting points so you are not stuck choosing between the standard spots when you want to angle a light or laser just right. The design will clear most suppressor installations too, which matters if you already know you want to run one down the road.
Installing the TEKKO 10 Inch M-LOK Rail
Installation uses a standard barrel nut, which is not included in the box, so plan on grabbing one if your build does not already have it. MFT calls for only minor assembly, and the rail will work with a standard front sight post, a low profile gas block, or a Picatinny rail gas block depending on how you have your upper set up. This 10" length is a solid match for mid-length gas systems, giving you good coverage over the barrel without hanging past where you actually need rail space.
Built to Outlast the Rifle
Every TEKKO rail is made in the USA and backed by MFT's Lifetime Warranty, so this is not a part you will be replacing again once it is on there. The patent pending mounting and indexing system locks the rail down tight with no wobble, which is the kind of detail you notice the first time you rest the forend on a barricade and it does not shift on you.

Frequently Asked Questions
Does the MFT TEKKO 10" M-LOK handguard come with a barrel nut?
No, the barrel nut is sold separately since this rail is designed to work with a standard AR-15 barrel nut you likely already have from your build. Any standard barrel nut will get the job done, so just make sure it matches your upper receiver threading before you order.
Will this handguard clear a suppressor?
MFT designed the TEKKO free float rail to accommodate most suppressor installations without interference. The free float design also means the handguard never contacts the barrel, so heat and vibration from a suppressed setup will not affect your accuracy.
What gas system length does the 10 inch TEKKO handguard fit?
This 10" length is built to pair with a mid-length gas system, giving you full coverage over the gas block area without extra length hanging past the front sight base. Always double check your specific barrel and gas block placement before buying to make sure the coverage lines up.
Can I mount a bipod or vertical grip on the TEKKO M-LOK rail?
Yes, the M-LOK slots run the length of the rail at the standard 3, 6, and 9 o'clock positions plus a few offset spots for more flexible placement. That covers bipods, vertical grips, lights, lasers, and any other M-LOK compatible accessory you want to add.
