Building a tactical rifle takes a lot of time and planning, but skipping over the necessary steps can be a fatal mistake. Among those steps, it is important that you decide on the right rail system for your weapon. A good rail will make the difference not only in how many accessories you can attach, but it will also affect your grip on the weapon in the field. When you want the absolute best available, you should check out the PWS 15″ KeyMod Rail For AR-15 / M4.
Using the KeyMod interface system developed by PWS, this improved design provides for a rail that comes without any picatinny surrounding the entire rail. Instead, it includes a full-length section on top and two 2” side sections to use with the system for additional attachments. It offers a truly free-floating design, which removes additional weight and makes for a more ergonomic grip in the field. To provide for more versatility, it includes QD sling swivel points at both the front and rear of the rail.
If you are looking for a great accessory rail to add to your longer barrel rifle, this will help give you the room you need to get everything attached.
