About the Handguard
The MK14 is the latest entry to the Geissele line up of Super Modular Rails. The new handguard design offers a smaller diameter and overall height to create a slimmer package. Included with the MK14 Super Modular Rail is an updated version of the proven Geissele Barrel Nut design, not only providing ease of installation but superior rigidity. The long surface contact of the 2.25″ barrel nut interfaces with the receiver creating a platform that can be trusted to be straight and true the entire length of the free float rail. The MK14 is 3d precision machined using 6061-T6 Aluminum due to its strong, rigid and lightweight properties.
Utilizing Magpul’s M-LOK technology in the 3, 6, and 9 o’clock positions allow the end user full customization and modularity of their rifle to securely mount lights, bipods and other firearm accessories. The Geissele MK14 Super Modular rail is finished in a durable and long lasting Type 3 Hardcoat Anodized available in either Black or Geissele’s DDC finish.
Barrel Information
This 16″ Government 5.56 NATO Mid-Length barrel was designed around the USASOC specs for an Improved Upper Receiver Group with a little bit of the Rosco touch as well. The longer gas system allows for a smoother gas curve which leads to managed dwell times. This combo creates a great balance of speed and performance..

Nbs premium series 16 inch upper
Just got back from the range shooting 75gr hornady bthp. I judge a upper by my ability to drop down from standing and with a hasty sling keep my shots inside the 10 ring on ar15 target at 200 and three hundred. With 40 rounds down the new upper with a exps2 sight install. So far mission accomplished. I know people are internet heroes and show impressive groups with their fingers. Have not met them on any firing line shoot there same groups in competion. May your life be peaceful.
