Heckler & Koch MR556A1 Upper Receiver Kit

Heckler & Koch

Las Vegas, NV --(Ammoland.com)- The MR556A1 Upper Receiver Kit allows high quality AR-style rifles to be retrofitted to HK’s famous pusher rod operating system.

An MR556A1 Upper Receiver Kit includes a complete barrel assembly, HK Free Floating Rail System handguard, complete bolt carrier assembly, HK buffer, and HK buffer spring.

The same operating system is used in the combat-proven 5.56 mm HK416 as well as the G36, XM8, HK417, and a variety of other Heckler & Koch arms. The Upper Receiver Kit is designed to be fully interchangeable with all high quality AR-style firearms that use retractable buttstocks and MIL-SPEC buffer tubes. Installation is accomplished by inserting the HK buffer and buffer spring and attaching the HK upper to an AR lower receiver using the standard takedown pins.

The Upper Receiver Kit is the core of the HK 5.56 mm proprietary gas piston operating system. It employs a piston and a solid operating “pusher” rod in place of the gas tube normally found in AR15/M16/M4-style firearms. The HK piston driven operating system virtually eliminates malfunctions that are common to the direct gas impingement system since hot carbon fouling and waste gases do not enter the receiver area. This is the same key feature critical to the success of the HK416 rifles used by leading military and law enforcement customers.

Like the MR556A1 rifle, the Upper Receiver Kit is made in the USA using German and American made components. The MR556A1 Upper Receiver Kit is classified as a part and can be purchased without a Federal Firearms License ( FFL). Suggested Retail Price is $2,195.

Brownells & Glockworx Slides For Glocks

Brownells.com

Des Moines, Iowa – -(Ammoland.com)- Through an exclusive partnership with Glockworx, Brownells is now offering a selection of slides pre-cut for popular optics to fit the Glock 17, in-stock and ready-to-ship.

Made for the Glock 17, the top rear of each Optic Cut Slide features a large precision-relieved slot allowing close-to-the-bore mounting of optics to minimize sight offset problems on short range targets. Also, the slide top near the front sight is ported to reduce overall slide weight, reduce recoil impulse and improve control of the pistol.

“The design teams at Glockworx and Brownells have worked together to develop four Glock slides to fit the Model 17 with pre-cut slots at the precise depth, width and angle to fit the most popular optics on the market.,” said Pete Brownell, President of Brownells Inc. “The custom work has been done already, just swap your Glock 17 factory slide for a Glockwork slide, install your optics or iron sights, and you’re ready to shoot.”

The Optic Cut Slides accommodate Dr Optic, Burris FastFire, JPoint, and RMR Optics. The cut on each slide model varies to fit the specialized base shape and mounting-screw pattern of those optics. There’s also an iron-sight-ready model. Because the optics sit down into the Glockworx cuts, they present a reduced profile and have very little offset between the sight and barrel – a critical advantage for those really close shots.

Six ports cut into the top of the slides reduce slide weight for faster target transitions and reduced recoil impulse.

Each replacement Glockworx slide is CNC-machined from aircraft-grade heat-treated stainless steel for long life. The sight cuts, ports, lowered ejection port, firing pin hole, breech face, and front and rear cocking serrations are precision-machined to ensure a precise fit and flawless function. The surfaces are finished with Zev Technology’s black DLC coating to resist corrosion and damage. All are currently available here.
