The Geissele Super Modular Rail MK1 (SMR) was developed as a side project to a rail R&D project Geissele was working on for one of our larger customers. Our SMR MK1 is designed to fit the M4 Carbine and all mil-spec AR-15 variants. The SMR MK1 does a good job in meeting the ten design specifications for a good M4 weapon rail, as outlined below.

1. ERGONOMIC
Instead of four sharp and jagged M1913 rails spaced at 90 degree intervals, the MK1 only has a M1913 rail at the 12 o’clock position while at 9, 3 and 6 o’clock is a rounded mounting surface for accessory rails. The rounded mounting surfaces feel good to the hand and provides for a comfortable grip.

2. SET-UP IS MODULAR AND FLEXIBLE
Accessory rails in the standard M1913 (Picatinny) configuration are provided with each SMR MK1 so accessories can be mounted where the shooter desires. Two short and one long accessory rail are provided with each SMR kit. There is also a QD mount at the receiver end that accepts an industry standard QD swivel. An accessory 45 deg QD mount can be purchased so a sling can be secured at an upper 45 deg position if so desired.

3. FREE FLOATING
The weapon barrel is completely free floating when an SMR is mounted. No force is put into the barrel from slings or bipods that could affect point of aim.

4. STRONG
The SMR MK1 is machined from a semi-billet extrusion made from aircraft grade aluminum. A semi billet extrusion is designed with extensive machining stock for 3D features that are machined directly into the rail so that the rail is one integral piece.

5. RIGID
Current infantry doctrine makes extensive use of accessories that require attachment to a weapon rail. Flashlights, visible and infrared lasers, night vision and thermal sights all require a rigid weapon rail so that zero is not changed when a bipod or sling is used to support the weapon from the rail. The SMR MK1 is a rigid interface for weapon accessories due to its precisely machined proprietary barrel nut and secure rail interface and clamping arrangement.

6. LIGHTWEIGHT
Use of aircraft grade aluminum and high strength steels in the SMR MK1 give the entire assembly a good strength and performance to weight ratio. Balance is as important as weight and the center of gravity of the rail is biased toward the receiver for good weapon handling characteristics.

7. ACCESSORY RAILS EASY TO INSTALL
Accessory rails are fastened directly to steel inserts that are imbedded into the rail aluminum. It takes literally seconds to install or remove an accessory rail without standing on your head to deal with non-captured plate nuts.

8. ACCESSORY RAILS ARE STRONG
The SMR MK1 accessory rails have machined in shear lugs that are a close fit into the cooling slots that are machined into the rail. Any force imparted into the accessory rail is transferred directly into the rail thereby bypassing mounting screws. This means that the mounting screws only need to hold the accessory rail on and not resist side loads that can make the screws loosen over time.

9. RAIL ASSEMBLY IS EASY TO INSTALL
Each SMR MK1 comes with a precisely machined, 2-1/4” long alloy steel barrel nut and a combination wrench that will remove the stock barrel nut and install the Geissele nut. The Geissele barrel nut needs no indexing to the gas tube so installation is a snap with just a torque value used for tightening. The rail is then slid onto the barrel nut and the precise barrel nut to rail fit precisely aligns the rail to the barrel. After indexing to the receiver rail two mounting bolts are tightened and the rail is secure.

10. RAIL IS EASY TO REMOVE
Just by loosening two screws and one of the indexing screws the Geissele SMR can be slid off the barrel nut for cleaning or gas system maintenance. Even a different rail with a different accessory
configuration can be mounted. As quick as it is removed the SMR MK1 can be re-installed with the precise barrel nut to rail fit maintaining sight and accessory zero.
