Free-Float Picatinny Quad-Rail Handguard w/Hand Tightened Jam Nut

In stock

This is a standard free-floated quad-rail for the AR-15/M16 platform. It is a free-float design, but a cap (sold separately) may be installed to close the front if your mission requires this.These are beefy robust feeling things. 

  • Monolithic (1-piece) style
  • Includes a barrel nut - this replaces your current barrel nut, if you have one.

You get:

  1. Quad-rail
  2. Barrel nut
  3. Thumb nut
  4. 4mm hex key

Compatible with:

  • All AR-15/M16 upper variants that use a standard barrel nut 
  • All weaver and picatinny accessories 
  • End caps for 0.750" and 0.936" diameter barrels

Installation Difficulty:

Tools required: armourer's wrench, barrel nut greaseupper vice block, and torque wrench strongly recommended

Installation Notes: Some fitting might be required due to variance between uppers. Also, it is recommended to tighten the barrel nut between 30-80 foot-pounds of torque.

One customer reported that the alignment pins inside the nut were just a little long and this caused the rail to wiggle; filing these pins just a few hairs shorter made the fit perfect.
