.223 Wylde

.223 Wylde

Our .223 Wylde is an actual Law Enforcement patrol-rifle. For that reason, we decided that the quality and reliability of Rock River Arms would be optimal. A departmental policy dictating that Patrolmen's AR-15's be chambered in .223 Remington, required a small side-step from our original direction; which was to build a 5.56 NATO rifle. The solution then was a relatively obscure caliber, known as ".223 Wylde" ...

The .223 Wylde is a modern improvement upon the standard .223 chamber design, in that it's been adapted to accept 5.56 ammunition; it also shoots more accurately than a standard 5.56. It's truly the best of both worlds. That said, our weapon was compliant and used to qualify with the Police Department. In addition to the Rock River Arms upper and lower receivers, we utilized their 2-Stage National-Match trigger. This particular trigger is lighter at approx. 4.5lbs, versus a standard mil-spec trigger weighing-in at 6.5lbs. It has virtually no creep; meaning it pulls much more smoothly than a mil-spec trigger and has a clean, crisp, break. This offers the shooter finer tactility, sharpening their overall trigger-control.

In the rear, we opted for a Magpul SL-K stock. This was due to it's compact design and rolled-toe, which reduces overall weight and fascilitates shouldering while wearing a vest. We also added a QD-cup, to enable the Officer to attach and detach a sling in a simpler fashion. Being a multi-purpose rifle, for both professional and personal use, durability became a big concern as well; therefore it's equipped with a parkerized and chrome-lined bolt-carrier group from Bravo Company Manufacturing (BCM). This bolt-carrier group is full-auto rated, and will easily withstand regular use while continuing to operate smoothly.

To maximize manueverability in and out of a patrol-vehicle, as well as meeting departmental policies, the rifle needed to be shorter without entering the realm of pistol-length or short-barrel rifles (SBR's). So we chose a standard 16" barrel with a 1:8 twist-ratio, but have recently made some upgrades to the original setup for the sake of weight-savings. Originally, we had opted to install a heavy-barrel (HBAR) by AR Stoner, with a carbine gas system, and spiral fluting along it's length. This feature fascilitates cooling by establishing a channel through which airflow is directed, juxtaposed with the larger barrel diameter that serves as a heatsink. Higher rates of fire cause the barrel to get hotter sooner, and these events affect what's known as "barrel harmonics"; that's the vibration in the barrel (unobservable to the naked-eye) which occurs as the round travels through it. That movement, occuring with every shot, produces changes in your point-of-impact (POA). Therefore, having a more massive barrel means it's stiffer, mitigating such movement. Also, it will disipate heat more evenly throughout it's length; ultimately helping you stay on target in a hostile situation, or during a weekend of running-and-gunning at annual-qualifications and other training events.

However, the heavy-barrel while proving accurate and reliable, did become an impediment during speed-related exercises such as "box-drills", where the shooter is expected to place six well-placed rounds into two seperate silhoette targets; two in each chest, and one in each head, as quickly as possible. Therefore, we improved upon the rifle with a brand new barrel from Faxon Firearms, containing their "Gunner" profile. This barrel type maintains a larger diameter in the rear-end of the barrel closest to the chamber, before tapering down to a pencil-profile at the muzzle. Therefore, the shooter retains the benefits of it's stiffer section, while gaining a weight-savings by the reduction of material in the front. The twist-ratio remains the same at 1:8.

Additionally, the gas system was improved as well, by changing it from a carbine-length, to a mid-length with the Faxon Firearms barrel. Now, the weapon's dwell-time (DT) has been reduced from 9" to 7"; meaning the amount of time in which the barrel is pressurized has been shortened. The result is a softer recoil, keeping hammered-pairs (double-taps) in tight proximity. While we had it disassembled, we further improved upon the gas system by upgrading the gas-block itself. We switched from a standard mil-spec block, to a Spike's Tactical edition, adustable gas-block, by Superlative Arms. With this, the amount of gas-flow is now customizable according to the sort of ammo being used. It limits over-gassing, which fascilitates reliable cycling of the action, while further reducing recoil. In the end, these changes have proven effective, and the overall weight of the rifle has been significantly reduced without sacrificing either range, or accuracy.

At the muzzle is a compenstator with integrated saw-tooth design. This is used to break through barriers such as windows, or to thrust upon impeding personnel as you enter a room. To fascilitate transitions between the shooters strong-side and support-side while using cover, we attached a Magpul MOE verticle fore-grip as well. Optics are by Sig Sauer, and work in conjuction with one another. They're a Romeo 5x red-dot sight and a Juliet 4 (4x24mm) magnifier. We chose the Romeo 5x because Police Officers need to respond when they hear the call, and in some cases without warning. So in addition to the auto-off feature, Sig Sauer's Romeo 5x comes equipped with a motion-sensor that activates your red-dot the moment it detects movement.
