AR-15 MK14 SUPER MODULAR RAIL HANDGUARD Reviews & Ratings

The Geissele MK14 Super Modular Rail tactical AR-15 handguard has a slim cross-section that makes it is ideal for shooters who use rail covers and/or a vertical grip - and who also employ the thumb-over-the-bore support hand grasp. Similar to their MK13 SMR, the Geissele MK14 delivers acres of real estate for mounting accessories, with M-LOK slots running the handguard’s full length at the 3, 6, and 9 o'clock positions.

The MK14 Super Modular Rail also sports an uninterrupted Picatinny rail running the full length of the top. Geissele even thoughtfully includes sockets for QD pushbutton sling swivels at the 11 and 1 o’clock positions at the rear.

Strong & lightweight machined 6061 T6 aluminum
Barrel Nut Wrench no longer included with the handguards.
Type III hardcoat anodized
Available in basic Black or Geissele’s Desert Dirt Color (DDC)
Proprietary free-float barrel nut included

Geissele also engineered the MK14 Super Modular Rail handguard to free-float the barrel using their easy-to-install proprietary barrel nut. The nut is 2.25" long, so there’s plenty of surface area for secure, rigid, straight anchoring of the handguard in place. Please note that a gas block is no longer included with these handguards.

Amazing

Arrived 3 days before eta. Condition was flawless and of course the QC is top notch. Can’t go wrong with Geissele and there’s no better place to get your parts or tools other than Brownells.

Beautiful rail. I am stupid

I submitted a previous review stating that the rail did not have the barrel nut included. I am stupid and did not look INSIDE the rail, it was just sitting in there. I retract my previous review. I am just holding it and admiring it right now.

Great product.

Its super high quality and built pretty robust. One negative is I paid the advertised price, not a big deal but when a guy pays geissele money on a build then you oughta get a sticker in the box. There wasnt a sticker and I was bummed. Still a 5 star product though.

No barrel nut. Don't forget to order.

Excellent machine job so smooth like butter. Lightweight but just feels tough like a quad rail gives you. I can't seem to find anything that geissele makes that ain't above and beyond.

The world's foremost handguard

This has to be the finest handguard I've ever used. Some has noted cons that this rail is heavier than the BCM, however, the weight difference is negligible and the craftsmanship of this piece is truly a work of art. Completely stole the show at my buddy's gun get-together. *Maybe* the only possible con someone could think of is that the super precise barrel nut is 1/4" visible past the first M-lok slot, so you can see the barrel nut after the rail is installed. nbd since they color matched the finish of the barrel nut. These Geissele guys left no stone unturned. Add to that the best customer service experience from Brownells and this is my best purchase of 2019. Lifelong customer.
