YHM M-LOK Handguards

Yankee Hill Machine

Yankee Hill Machine Co., Inc. announced the addition of M-LOK to its line of hand guards for the AR style rifle. The new YHM-5290 S.L.M. and YHM-5320 MR7 hand guards were developed in response to customer demand. Previously, the company made KeyMod hand guards but not M-LOK.

The MR7 has a Picatinny type rail at the 12 o’ clock position and M-LOK attachment points every 45˚ around its circumference. The company states the MR7 will be available in carbine, mid-length and rifle lengths. Currently, Yankee Hill Machine lists the rifle length (12.7″) hand guard on its website with a suggested retail price of $160.

For a thinner hand guard, the S.L.M. is a credible option. The rifle length version of the S.L.M. weighs 9.7 ounces. Similar to the MR7, the hand guard has a Picatinny rail on top. M-LOK attachment points are at every 90˚ instead of 45˚. Like the MR7, different lengths will be offered. This rifle length rail system has a suggested retail price of $230.

Both hand guards are made of 6061-T6 aluminum and have a hard coat anodized black finish. A barrel nut, wrench, screws and instructions ship with these rails.

Despite following other standards to the market, M-LOK is growing in popularity with many companies offering guns equipped with M-LOK hand guards standard.

    Steve et. al., I love the website, but for the love of guns, please fire the s*** out of your webhost/tech-co. 9/10 articles are automatic redirects. It has nothing to do with adblock software, it happens across multiple OS’s, browsers, devices, across the country, etc.

    Something is not right in hooville. I’ve never had to host a website, I’ve never run a website and paid someone to host for me, but I have to imagine that the broken functionality of the website has gone on for so long past any forgiveness for a tech-solution company that has been charged with maintaining the website.

    Now, if it’s a family member running the website and doing their best, that’s one thing- Carry on. But if TFB is paying a service and they’re clearly not doing their job, then I’d hope that someone is considering going with someone else. Contract or not, they’re not holding up their end of the bargain.

    Just my unsolicited thoughts (it’s not just my inconvenience, but you’re undoubtedly losing casual browsers)

      Been reading the site for years. Never had that problem – not once.

      Where are you browsing from? Your host might be blocking you. I have not experienced such problems.

    Do these new guards fit on the old (yhm) nut and ring? Most of yhm’s older guards use the same type, a couple models do not.
