The Super Modular Rail (SMR) MK4 M-LOK is Geissele's ultra-lightweight M-LOK option. These rails are purpose-built and feature integrated M1913 picatinny rail sections at the fore of the rail in the 3, 6 and 9 o'clock positions. Maximum venting for heat dissipation also dramatically reduces the rail's overall weight, while maintaining its same strong and rigid platform. Utilizing Magpul's M-LOK technology at the 3, 6, and 9 o'clock positions, as well as the upper 45 quadrants. The SMR MK4 is both versatile and modular, allowing the user to tailor their platform to his or her unique needs.

The SMR MK4 also features Geissele's proprietary 2.25" long barrel nut. This increases the surface contact where the rail interfaces with the receiver and creates a platform that can be trusted to be straight and true the entire length of the free float rail. This increases accuracy and zero repeat ability during disassembly and reassembly when performing maintenance.

About Geissele Automatics

THE GEISSELE MISSIONTo prove, every day, that the Golden Rule works: "Do to others as you would have them do to you" Luke 6:31."We Manufacture Confidence" FOR THE COMPETITORGeissele Automatics was established in 2004 as a manufacturer of trigger mechanisms for the AR15 rifle. Our first trigger, the Hi-Speed National Match, was designed by our Founder, Bill Geissele, for CMP and NRA Hi-Power Rifle competition.FOR THE WARFIGHTERAlthough designed for target shooting, the Geissele Hi-Speed trigger was found by the U.S. Military to have applications in semi-automatic sniper weapons. In 2005 Geissele Automatics received a request from the Department of Defense: "Can you build us a select-fire trigger that is as good as your Hi-Speed?" In response, Bill designed the Geissele Super Select-Fire trigger (SSF). After rigorous testing the SSF was adopted by entities in the U.S. Special Operations community and has become their trigger of choice for M4 carbine based weapons.FOR THE PROTECTORA derivative of the SSF trigger was developed to meet the needs of law enforcement and civilians who do not need select-fire capability. This trigger, the Super Semi-Automatic (SSA,) combines stellar performance with the safety, reliability and forgiveness for which 2 stage triggers are known.

"The DDC Geissele mk4 rail is amazing just as expected. I can thank Geissele for that and I thank Evike for shipping it out fast (ordered Sunday and it shipped out on Monday). The only gripe I have with Evike is that in the listing ad, it stated “a geissele super gas block will be included” (being that I am installing on a real ar platform and not an air soft) I would have appreciated the block. I read that the barrel nut wrench would not be included but not the gas block). Other than that, again I couldn’t thank Evike more. I’ll possibly order more things sooner and later.
