Ruger Piston Driven Uppers for SR-556 AR Platform
Ruger Piston Driven Uppers for SR-556 AR Platform
Ruger Piston Driven Uppers for SR-556 AR Platform
Sturm, Ruger & Company, Inc. announces the availability of three, AR-style upper receiver assemblies featuring the innovative two-stage, piston driven performance of the SR-556® family. These rugged and reliable SR-556 piston driven uppers run cleaner, cooler, and are easier to maintain than traditional gas driven systems, offering significantly improved reliability. SR-556 upper assemblies will be available through firearms retailers and ShopRuger.com.
Now all AR owners can enjoy the features of the SR-556 platform, including the patent pending two-stage piston driven operating system that provides a smooth power delivery stroke to the action and vents combustion residue out of the bottom of the gas block. The four-position adjustable gas regulator allows the operator to tune the rifle to specific ammunition and rifle conditions, minimizing recoil and maximizing reliability and long-term endurance. Reliability is further enhanced by a one-piece bolt carrier with an integral transfer key. Designed for long-lasting accuracy, the chrome lined barrels are cold hammer-forged from Mil-Spec 41V45 Chrome-Moly-Vanadium steel.
The standard SR-556 upper chambered in 5.56 mm NATO/.223 features a heavy contour, 16.1″ barrel with a 1:9 twist rate, and is capped with a Mini-14/SR-556 flash suppressor mounted on 1/2-28 threads. A one-piece, ten-inch quad rail handguard provides ample room for mounting sights, optics and accessories. Made exclusively for Ruger, this SR-556-specific handguard is pinned to the upper receiver, creating a near-monolithic upper receiver assembly and providing a rugged mounting system for the piston driven transfer rod.
A carbine-length version of the popular SR-556 two-stage, piston driven AR-style upper is also available. The carbine upper features a heavy contour, fluted barrel that is 1-3/4″ shorter and a half-pound lighter than the barrel on the standard SR-556. The 1:9 twist rate, 16.1″ barrel on the carbine features an integrally machined flash suppressor, which minimizes the overall length of the barrel while complying with ATF regulations for civilian and commercial sales. This carbine version maintains the mid-length gas system and heavy (.850″) barrel contour under the handguard, but the barrel is fluted for weight reduction and to promote barrel cooling.
Those seeking to equip their modern rifle with ample power for hunting medium-sized game or greater muzzle and downrange energy capability for defensive or tactical roles can select an upper chambered in the capable 6.8 SPC caliber. The SR-556/6.8 features upper features a heavy contour, 1:10 twist barrel with a standard SAAMI 6.8 SPC chambering. The chrome-lined, cold hammer-forged barrel is 16.12″ long, is threaded 5/8-24, and is capped with the effective and distinctive Mini-14/SR-556 flash suppressor.
All three uppers are equipped with folding, back-up iron sights. These rugged, high-quality sights co-witness with Mil-Spec optics, and are easily removed or replaced. The sights can be folded down with the push of a button, or quickly flipped up with your thumbs. The windage adjustable rear sight includes an instantly converted short and long-range aperture, and the protected front sight is elevation adjustable.
Durability and performance of the SR-556 is enhanced with the use of high-performance finishes: The barrel and gas block are chrome lined, while the piston, bolt, bolt carrier, and extractor are chrome plated. The piston driven transfer rod is electroless nickel/Teflon coated. The flash hider and the exterior of the barrel, gas block, and regulator are manganese phosphate coated. All aluminum parts are Mil-Spec hard coat anodized.
The SR-556 rifle and carbine uppers chambered in 5.56mm NATO are shipped with three, thirty-round Magpul PMAG™ magazines. These lightweight magazines feature a storage/dust cover, a stainless steel spring, and a self-lubricating, anti-tilt follower. The 6.8 SPC chambered upper is shipped with one five-round magazine and two twenty-five round magazines. Three rail covers, provided with each upper, provide a comfortable ergonomic hold when carrying or shooting. All Uppers are shipped in a padded carry case that features the Ruger logo, hook-and-loop fasteners to stabilize the rifle within the case, and internal magazine pockets.

AR-15 Gas Blocks
AR-15 Gas Blocks:
Gas Blocks
Update: November 28 2010. It’s getting hard to keep up with ever changing links from manufacturers and stores. To simplify the process rather than directing visitors to the exact product link I am changing the landing pages to be brand specific rather than part number specific.
The gas block is one of the major components that make up the gas system on which the rifle operates. Without a gas block the AR15 will not cycle. There was a time one there was only one gas block option, that option was the front sight gas block (FSGB). Today its a different world. There’s adjustable gas blocks, low profile gas blocks, railed gas blocks and folding front site gas blocks. The gas blocks are manufactured from aluminum or steel. Steel is preferred for AR15 rifles that will see high round counts.
Note: If you are removing a standard A2 style front sight gas block the pins that fasten it to the barrel must be removed and replaced in a specific direction. Brownells makes a special tool to make this easy and to prevent you from damaging the front site gas block. This tool is called AR-15 Front Sight Bench Block
. See the tool below and click the image to see more information at Brownells.
Noveske Switchblock Adjustable Gas Block
Adjustable gas block reduces gas flow to ensure reliable function during single-shot operation or when using sound suppression devices. Helps reduce felt recoil and minimize carbon buildup on the bolt carrier and inside the receiver for less frequent cleaning without compromising reliability. Three-position selector drum locks into position and is easily adjusted with the included wrench. Suppressed position reduces excess back pressure to safe levels when using noise limiting devices. Unsuppressed position allows normal weapon operation. Off position enables single-shot operation, preventing spent cartridge ejection while providing a reduced weapon sound signature. Replaces factory gas block, and clamps securely around the barrel with two steel Allen head screws. Gunsmith installation recommended.

VLTOR has some nicely profiled gas blocks available in various bores. With the various rail systems currently being offered for the AR15/M16/M4 weapon system, the Vltor Low-Profile Gas Block is small enough to fit inside most rail systems. These gas blocks are an excellent replacement for the archaic fixed sight tower gas block, which has been the standard since the early 1960’s.
The Vltor Low-Profile Gas Block covers one-inch of the barrel’s surface and is made to the tightest tolerance. These gas blocks are offered in two materials, 4140 carbon steel and 17-4PH stainless steel. The 4140 gas blocks are manganese phosphate (black finish) to match barrels with similar finish. The stainless steel gas blocks are blasted to give a matte gray finish.
All current models are made to fit barrels that feature a .750 or 3/4-inch gas block mounting surface. In 2007, Vltor will offer a gas block that will mount to a .625 or .5/8-inch diameter barrel.
AR-15 Bolt Catch Pin Punch
AR-15 Bolt Catch Pin Punch
AR-15 Bolt Catch Pin Punch
Removing the AR-15 Bolt Catch Pin is easily one of the most frustrating tasks for those work on AR-15 rifles. The difficulty lies in that the pin is very close to the lower receiver. If the closeness to the receiver wasn’t enough of a challenge there is also a protrusion in an AR-15 lower receiver that blocks a straight on approach to the AR-15 Bolt Catch Pin.
Brownells has made the task of working with the AR-15 Bolt Catch Pin much easier with a modified roll pin punch.
The punch is modified to have it’s center line close the the receiver while straddling the hump in the lower receiver.
You can see how the Bolt Catch Pin gets close to the receiver with only minor interference from the hump.

DUECK DEFENSE – Rapid Transition Sight
DUECK DEFENSE – Rapid Transition Sight
Check it out at Brownells
Top 3-Gun shooter and IPSC Grand Master: Barry Dueck, has designed the RTS sight system which provides the competitive or tactical shooter with the quickest transition possible from optical to iron sights, greatly increasing efficiencies when dealing with near and far targets.
“I realized that when shooting close targets on the move I was more effective with standard M4/M16 iron sights than when using anything else. Being that I still performed better at longer ranges with an optical sight, I came up with a sight design that allowed for both. It also solved the problem of trying to co-witness sights because you now have two independent sighting systems that are always ready.”
~ Barry Dueck
Mounts At 45° Offset From Primary Optic For Instant Transition To Backup Sights
Rugged machined aluminum backup sights mount a on Picatinny-railed rifle at a 45° offset angle to enable instant transition from primary optic simply by tilting the rifle. Ambidextrous design can be mounted to on the left or right side of the receiver. Eliminates the need to co-witness backup sights through your optic.

Mount rear sight to receiver rail and front sight to handguard top rail.

Carlson Adjustable Muzzle Brake
Carlson Adjustable Muzzle Brake
Two-piece machined steel muzzle brake employs an adjustable, push-down, spring-tensioned, rotating cover design with three port hole sizes to choose from to direct combustion gases upward to virtually eliminate muzzle rise and felt recoil. Enables fast, accurate follow-up shots in semi-auto mode and superb control in full auto. Designed by Greg Carlson especially for reloading enthusiasts who enjoy experimenting with different powder weights, bullet grains, and loads for increased velocities and shooting performance. Cover is selectable for either a large, medium or small gas vent port by depressing the knurled selector cylinder and aligning port and cover hole; release cover to activate locking pin mechanism. Gas escapes upward to counteract upward force on the muzzle without directing concussion and noise back at the shooter. Solid bottom prevents kicking up dust signature when shooting prone.
