Adjustable Gas System

The POF adjustable gas system consists of three major components, the gas plug, gas piston and operating rod. Residual gasses behind the bullet are routed into the gas block which drives both the piston and the op rod rearward in turn cycling the firearm. Suppressors add back pressure to a firearms operating system and thus increase bolt speed. This causes premature wear on the firearm and can even result in the bolt catching the discharged casing also known as “stove piping”. The POF gas system allows the user to restrict, and even shut off, this extra back pressure by simply rotating the gas plug. The Watson Chambers Edition allows the user to tailor the rifle to virtually any 300 blackout bullet and suppressor combination. 

Bolt Carrier Group & Roller Cam Pin

Bolt Carrier Group

POF's one piece high phosphate nickel coated bolt carrier is manufactured with the mechanical key built into the body and positioned behind the cam pin. This patented design helps reduce carrier tilt. Our bolt carrier group features a chrome plated bolt, extractor, and firing pin. The finishes are both corrosion resistant and introduce lubricious characteristics to the action.

Roller Cam Pin

POF's patented roller cam pin is just one more example of how we strive to reduce friction and drag in the action. Standard AR cam pins feature a square steel head that literally grinds and carves away at the inside of the receiver. POF’s NP3 coated roller head actually rolls inside the channel of the upper thus eliminating friction and prolonging the life of the upper.


Tripple Port Muzzle Brake

Designed to precisely compliment the POF platform the nitride heat-treated muzzle brake controls gas dispersion and reduces muzzle rise. It is effective in allowing the shooter to have faster follow up shots and has unbelievably soft felt recoil. It features blunt strike prongs and includes our nitride heat-treated collar jam nut.


Modular Railed Receiver

The patented Modular Railed Receiver (M.R.R) is POF’s crown jewel for precision and extreme rigidity. This is a two piece upper assembly with a free-floating monolithic handguard that slides on and interfaces directly to the upper assembly thanks to our upper’s reinforced backbone. This backbone is five-times thicker than standard flattop platforms.

The suspended handguard keeps your grip and accessories from weighing on the barrel and reduces stress and flex in the barrel extension area. This ensures both extreme rigidity and accuracy by directing stress risers toward the upper assembly’s strongest, most reinforced materials.


Maxim CQB PDW Telescoping Brace

The Maxim Brace maintains pistol compliance and allows for full adjustability to fit any user. Now fully legal to shoulder, the brace provides comfort in a variety of different uses. Inside is the JP Enterprises Silent Capture Spring System. 

By eliminating the friction found in standard buffer setups, the JP Silent Captured Spring also allows for smoother action resulting in less sound as the bolt cycles.
