POF-USA P415 Pistol with Dead Air Silencers Sandman K

Patriot Ordnance Factory (POF-USA) now offers pistol versions of all of its rifles. I previously reviewed the 7.62×51 NATO POF-USA Revolution Pistol  for Spotter Up  In this article we’ll take a look at the POF-USA P415 Pistol. 

The P415 was engineered over decade ago ago to be “virtually unstoppable in unfavorable conditions.” It’s a product of POF-USA’s continuous development to the AR platform. The P415 is available in both 5.56x45mm NATO and .300 AAC Blackout (300 BLK). The P415 Pistol provided for evaluation was chambered in 300 BLK. 

The 300 BLK has become a very popular round. It gives options not found in any other factory cartridge for the AR-15/M4 platform. The cartridge was developed to provide improved performance from the AR platform with only a barrel change, using standard bolts and operating systems. The design parameters of the 300 BLK make it an ideal round for shorter barrels and especially for suppressed applications. Supersonic loads provide ballistic performance close to that of the 7.62x39mm, while subsonic loads vastly outperform the 9x19mm for suppressed applications.

The P415 Pistol is built on the POF-USA Gen 4 lower receiver. The Gen 4 lower incorporates a number of features, including an ambidextrous bolt hold open and release with enhanced bolt catch, ambidextrous safety selector, Teflon® receiver tension screws, over-sized mag well flare and over-sized integrated trigger guard with grip relief.

Although the 300 BLK was developed around standard AR-15/M4 magazines, they were designed for the 5.56 NATO thus limiting the performance and compatibility. While some 300 BLK rounds function reliably in 5.56 NATO magazines, others don’t interface correctly with the contact areas of the magazine. Dust and fouling from blow back exacerbate the problem, especially with some of the subsonic and monolithic-bullet rounds, creating side pressure induced friction, slowing stack movement. For these reasons, I recommend a magazine specifically designed for the cartridge (such as the excellent Magpul® PMAG® 30 AR 300 B GEN 3) for optimal performance with all cartridges.

Technical Specs.

Let’s start off with the technical specs of the P415 Pistol. The P415 Pistol has all of the cutting-edge proprietary features that one has come to expect from POF-USA plus some new ones, as well.

The P415 is built on the POF-USA Gen 4 lower receiver. The Gen 4 lower incorporates a number of features, including an ambidextrous bolt hold open and release with enhanced bolt catch, ambidextrous safety selector, Teflon® receiver tension screws, over-sized mag well flare, ambidextrous magazine release, ambidextrous recessed finger rest and over-sized integrated trigger guard with grip relief.

The bolt carrier is of one-piece design with the bolt carrier key built into the body and built into the body. The patented design features that reduces carrier tilt. The bolt carrier is electroless high-phosphate nickel coated. The bolt carrier group features a chrome plated bolt, extractor and firing pin. The finishes provide corrosion resistance and lubricity.

POF-USA’s patented E2 dual-extraction system incorporates four small channels built into the chamber to allow a small amount of gas pressure to push against the neck of the spent case as the extractor is pulling to the rear. This assists in extraction by removing a considerable amount of work that would otherwise need to be performed by the extractor alone.

The P415 Pistol features proprietary POF-USA match-grade single-stage, non-adjustable, drop-in trigger system that boasts a solid 4.5-pound pull weight. It also features custom-fit stainless steel KNS Precision Anti-walk Pins. It’s an outstanding trigger.

The P415, as with all POF-USA firearms, features the company’s proprietary match-grade single-stage, non-adjustable drop-in trigger. The trigger is pre-assembled in a hard-coat anodized aluminum housing with urethane rubber feet. The trigger, disconnect and hammer are A2 tool steel and nitride heat treated to 70 RC for strength and corrosion resistance. It comes with KNS Precision stainless steel non-rotating anti walk pins specifically designed for the company’s ambidextrous lower receivers.  It’s one of the best factory triggers on the market, bar none. The trigger has a 4.5 pound pull with no-slack and an exceptionally crisp, clean break and no over travel It has a tactile reset.

The P415 features POF-USA’s patented 5-position adjustable Regulated Short-Stroke Gas Piston System. It consists of just three major components: the gas plug, gas piston, and operating rod. Instead of gas being directed into the bolt carrier as is the case with a direct impingement (DI) system, in a piston operated AR the gas pushes a piston that acts on an operating rod, that acts on the bolt carrier, cycling the action.

The piston system reduces two problems associated with DI systems: carbon fouling and timing issues (with short barreled rifles and with the use of suppressors). The POF-USA gas system allows the user to restrict and even cut off the added back pressure when suppressors are employed.

Reliable functioning with subsonic ammunition, even with an adjustable gas system, is greatly impacted by both the ammunition and suppressor. POF-USA offers a free suppressor tune-up for all its firearms. They will install and time the suppressor mounts, and tune the gas system to your suppressor and chose of ammunition, including opening up the barrel gas port if necessary, all at no charge. If you will be shooting suppressed, I highly recommend that you take advantage of it.

P415 Pistol features POF-USA’s patented 5-position adjustable Regulated Short-Stroke Gas Piston System that consists of only 3 components.. The gas system is easily adjusted by simply rotating the gas plug.

Although POF-USA originally utilized the SB Tactical SBA3 adjustable Pistol Stabilizing Brace on its pistols, current production pistols feature the Mission First Tactical BATTLELINK Minimalist Pistol Stabilizer™. Both braces utilize a standard mil-spec carbine buffer tube. The P415 Pistol provided for my evaluation was equipped with the SB Tactical SBA3 brace.

The P415 Pistol has a POF-USA 5-position mil-spec 7075 aluminum receiver extension (buffer tube) that features carrier cradle extensions to ensure that the carrier is always supported, even when the bolt carrier is fully forward, to prevent carrier tilt and premature wear of the buffer tube. The buffer tube detent is designed to double as a lock that inhibits the buffer tube from rotating and becoming loose.

The P415 features a Mission First Tactical Engage AR15/M16 Pistol Grip Version 2. It has a 15-degree angle that provides improved comfort and control, compared to the greater angle of a standard A2 grip, as well as texturing to provide a positive grip surface.

The P415 has a 10.5-inch chrome alloy match-grade barrel with either a 1:7 (5.56mm) or 1:8 (300 BLK) twist. It’s nitride heat treated for full corrosion resistance.  The barrell is equipped with a nitride heat-treated triple-port Dead Air Silencers Keymount muzzle brake adapter to control gas dispersion and reduce muzzle rise. The Keymount brake allows for faster follow-up shots and substantially reduces felt recoil. It’s suppressor ready and allows you to quickly attach a Dead Air Sandman-L™, Sandman-S™, or Sandman-K™ suppressor to the pistol. It will also fit the Dead Air Key-Mo™ adapter for the SilencerCo® Omega™ and Saker™, allowing you to use those suppressors, as well.

The P415 features POF-USA’s proprietary oversized aluminum heat sink barrel nut. It’s over three inches long and completely encompasses the chamber and throat area of the barrel, dissipating heat where expanding gas pressures peak. It provides 17 times more heat dissipation than a standard AR barrel nut. The long barrel nut also provides more guiding surface for the operating rod to ensure constant positive contact with the bolt carrier.

The P415 Pistol is equipped with a nitride heat-treated triple-port Dead Air Silencers Keymount muzzle brake adapter that’s suppressor ready. It greatly reduces muzzle climb and perceived recoil with minimal concussion compared to traditional muzzle brakes.

The enhanced backbone receiver also adds substantial increased rigidity to the overall platform. It’s five times thicker than standard flattop platforms. POF-USA’s patented Modular Railed Receiver (M.R.R.) or M-Rail provides additional rigidity and precision. It’s a two-piece upper assembly with a free-floating monolithic handguard that slides onto the upper receiver and interface directly with it. The free-floating POF-USA handguard keeps any accessories from weighing down on the barrel and reduces stress and flex in the barrel extension area, resulting in increased accuracy.

The P415 features POF-USA’s redesigned Edge rail handguard. The size has been reduced from the original by nearly 20%, making the width only 1.75 inchesThis not only reduces weight but also provides better ergonomics to the shooter. The Edge rail features full M-LOK® compatibility, a front top and bottom section of rail for sights and a bipod or other accessories, and features four QD sling mount slot.

Range Testing

I met up with Josh Locatis of Tap Rack Bang Creative at the Rio Salado Sportsman’s Club in Mesa, Arizona, for some range time with the P415 Edge Pistol. The P415 Pistol provided for evaluation was equipped with a Trijicon® MRO® (Miniature Rifle Optic) 1x25mm reflex sight with 2 MOA red dot. Josh brought along a Dead Air Silencers Sandman-K suppressor for use in our tests. The super-compact Sandman-K is the shortest and lightest of the outstanding Sandman family of suppressors. Designed for CQB, the Sandman-K has an overall length of just 5.4 inches and weighs only 12.8 ounces. It adds just 2.9 inches to the overall length of the host firearm.

Black Hills Ammunition 300 Whisper®/Blackout 125gr OTM ammunition was employed for our range testing. Black Hills makes outstanding ammunition. All of the loads are crafted and hand-inspected to ensure the utmost quality and consistency. The P415 Pistol was tested both with and without the suppressor.

The 5.4-inch Dead Air Silencers Sandman-K QD suppressor adds only 2.9 inches to the length of the firearm. It’s multi-caliber rated up to 300 Win Mag.

We did a mix of offhand shooting and bench work off a bipod and off a rest. The Dead Air brake did an outstanding job of controlling muzzle climb and perceived recoil, although as to be expected with any brake there was a perceived increase in muzzle blast. There were no malfunctions.

The Dead Air Sandman-K performed admirably for such as compact suppressor. There was some POI shift, as is normal when mounting a suppressor, but it was repeatable and minimal. The P415 piston system made suppressed fire a pleasure, without all of the unpleasant gas blowback to the face that one would have with a suppressed DI rifle.

Accuracy testing was conducted without the suppressor. The P415 Pistol produced 5-shot groups of 2 inches or less at 100 yards with the Black Hills 125gr OTM. Groups were shot from a bipod with the MRO 2 MOA red dot sight. POF-USA states that the P415 Pistol is capable of one MOA or better accuracy.

Velocities were measured using a Caldwell Ballistic Precision Chronograph Kit MFG#721122. Temperature was 87 degrees F. Elevation was approximately 1,240 ft. All speeds were measured without a suppressor and in feet-per-second (fps). The Black Hills 125gr OTM had an average velocity of 2,248 fps with a maximum deviation of 23 fps from the 10.5-inch barrel. 

The design, operating system and muzzle break on the P415 Pistol do an outstanding job in mitigating recoil and muzzle climb. The trade-off with a muzzle brake is increased muzzle blast. Where that’s an issue, it’s simple to remedy as the P415 Pistol accepts any muzzle device with a 5/8-24 thread in the case of the 300 BLK or 1/2-28 thread in the case of the 5.56mm.

The compact size and lightweight of the P415 Pistol make it a fast handling gun that, coupled with the controllability, make it a great fighting platform suitable for dynamic urban applications. And it’s surprisingly capable for longer range applications, as well, thanks in part to the SBA3 Pistol Stabilizing Brace.

Final Thoughts

The P415 Edge Pistol is outstanding firearm for anyone looking for a short barrel AR. It gives you POF-USA’s acclaimed quality and performance in a non-NFA platform.  It’s available in in Black and Burnt Bronze. Suggested retail is $2,019.00 or $2,149.00, depending on the finish selected. All POF-USA firearms have a 100% satisfaction guarantee and come with a limited lifetime warranty.
