Geissele 15in Super Modular Rail MK4 M-LOK Up to 11% Off — Free 2 Day Shipping w/ code 2DAYAIR — 2 models
I recommend using the Geissele Super Gas Block with the Geissele 15in Super Modular Rail MK4 M-LOK. However, we currently do not have this gas block available.
The Geissele 15in M-LOK Super Modular Rail MK4 will fit Mil-Spec AR15's. So it will work with a Ruger AR556, but if you have a Ruger AR556 with an A2 front sight gas block that will need to be removed and replaced with a low profile gas block.
I recently scored this for my AR 20” rifle swapping it out replacing older style YHM free floater . The Geissele barrel nut is well machined and thought out, i recommend getting their tool for the few bucks to make ur life easier. The handguard is ...

The fit and finish is top notch. The rail is nice and wide so those of you with large hands will love this. The only thing I can complain about is the variation of color between individual rails, but they are very upfront about this so I can’t fault ...

Awesome. Beautiful. Love the color.
Fits more secure than any rail.
Super as are all Geissle products. Easy, secure install!!!!!!!!
Con ............ PRICE but you get what you pay for. Only comparable is Faxon carbon fiber, also expensive!!!
Let's get this out of the way first: Yes, it's expensive. However, for the price you are also getting a very nice low-pro gas block, so if you can manage a coupon and then back out the cost of the GB, you're closer to $200 than $300, and that's easie...

This is an absolutely beautiful piece of machinery. Quality on every inch of this Geissele artwork. It is very easy to install (only about 15 minutes). The fit of the handguard over the barrel nut is immaculate.

Product Info for Geissele 15in Super Modular Rail MK4 M-LOK
The Super Modular Rail MK4 M-LOK from Geissele is an ultra-lightweight option for full-size AR builds. At 15 inches in length, these rails are purpose-built and feature integrarted Picatinny rail sections at the front of the rail in the 3, 6, and 9 o'clock positions. The free-floating design also lends itself to efficient barrel venting, ensuring heat can dissipate swiftly after you fire.
The MK4 Super Modular Rail also has M-LOK connections along the rails and in the upper 45 quadrants so that you can mount a variety of accessories to customize your weapon to your exact needs. The modular nature and versatility of the MK4 is what makes it stand out from the crowd, giving you options for tactical, functional, and sport shooting upgrades.
The Super Modular Rail MK4 also features the Geissele's proprietary 2.25-inch long barrel nut, which is larger and stronger than other varieties. The extra length increases the nut's surface contact where the rail interfaces with the receiver, creating a platform that is straight and true. With the extra rigidity, you can maintain your accuracy and zero-in your optics reliably.
