JP Enterprises just released their new 9mm Silent Captured Spring which is a complete buffer and spring system for 9mm AR-15 carbines and pistols. The concept of the JP Silent Captured Spring is to eliminate the spring noise in the buffer tube than many find irritating and make the smoothest possible feel to the action. The standard AR15 variant of the Silent Captured Spring has been extremely popular and has consistently been a top product with our customers. But the 9mm model is brand new for July 2014. We have had them on order with JP for months and finally got the first batch of them in. They have 4 weights instead of 3 on the .223 model and the weights are tungsten instead of steel to provide more weight for the 9mm blowback operation. One thing to note is that all JP Silent Captured Springs, this one included, require the guide rod to be able to extend into the rear portion of the bolt/bolt carrier as the action cycles. On most 9mm bolts there is a steel weight secured into the rear of the bolt with a roll pin to add weight. In order to use the JP Silent Captured Spring system, this weight must be removed. The buffer system adds enough mass to for it to still function properly with the weight removed from the bolt. This is a simple operation just requiring a punch to drive out the roll pin and slide the weight out the rear of the bolt. So for those looking for a smooth buffer system for their 9mm AR15 carbines, pistols or SBRs, here’s a great new option for you.

Sprinco has been making recoil management guide rods for semi auto pistols for decades. They started out back in the early days of IPSC and USPSA practical shooting competitions making recoil guide rods for 1911s. Over the years they have upgraded the design and manufacturing methods to make it a very refined system and expanded the product line to include a wide array of pistol models. Sprinco is also an industry leader in spring technology for handgun recoil springs, AR-15 buffer springs, extractor springs and even magazine springs.
The advantage to a Sprinco recoil guide rod is reducing recoil and muzzle flip by reducing the slide to frame impact. At the end of the recoil cycle of a semi auto handgun, the slide impacts the frame to stop it’s rearward travel and then the recoil spring pushes it back into battery loading the next round on the way. The Sprinco guide rod has a secondary spring that is engaged during the last quarter inch or so of rearward travel. The primary recoil spring slows the slide to some degree and the secondary spring slows it even further prior to impacting the frame. This happens after extraction and ejection has already happened and when things need to slow down. Normally the slide impacts the frame pretty hard resulting in part of the recoil and muzzle flip felt by the shooter. Having this secondary spring decelerate the slide faster just prior to impact makes things feel smoother and results in less muzzle flip and faster follow up shots.
Some shooters have concerns that this will interrupt normal cycling and manipulation of the pistol. But unlike synthetic buffer inserts that actually shorten the overall travel of the slide, the Sprinco recoil guide rods allow the slide to travel it’s full distance which is definitely the superior approach. The last quarter inch of travel does have more spring tension, so when manually cycling the action it will take slightly more effort to lock open the action, but you get used to it very quickly and it then feels normal to you. Furthermore, when you are cycling the action to load and unload without locking the slide open you won’t notice any increase in spring tension at all since it doesn’t need to travel the full distance to do those functions. The strength of the secondary spring on a standard guide rod model is based on standard power practice and self defense loads for each gun and caliber but will work fine with +P loads as well. If you plan on shooting a steady diet of +P or heavy recoiling loads in your pistol, then you may want to select what they call their COR-BON models which have a heavier secondary spring. But if you want it to cycle properly with standard loads, then you’ll need to stick with a standard model. Some of their models include primary recoil springs with the guide rod such as with Beretta and Glock pistol models. While others use the factory recoil spring with the Sprinco guide rod such as with Sigs.
In Sig P220, P226 and P229 pistols, the factory braded wire recoil spring is used with the Sprinco Recoil Guide Rod. The guide rod comes with a stainless steel bushing for the front of the side to actuate the secondary spring. One thing you notice as you first open the package is the highly polished finish of the guide rod. It looks like a chrome finish, but is actually hand polished stainless steel. Installation is simple and obvious and only takes seconds. Once you reassemble the pistol and cycle it you feel the increased spring tension in the last quarter inch of slide travel. Once you cycle it a few times you get start getting used to the feel of it and it seems to break in pretty quickly. When shooting it, you do experience less muzzle flip which is especially helpful on a Sig with their high bore axis. Accuracy and reliability remains excellent characteristic of Sig pistols. What I like most is knowing that the aluminum frame is not taking near the impact it used to take, thus increasing service life. All in all, an excellent product.
CQB, or close quarters battle, is all about precision, speed, and aggressiveness. The shock of attacking operators swiftly penetrating OPFOR’s sanctum is essential to any successful mission. Yet, without the proper equipment, it is nearly impossible to maintain a high level of operating efficiency. Long barreled rifles would get caught on obstacles, unnecessarily heavy weapons would exhaust the shooters, and compensators would redirect the muzzle blast to the sides, often times right into the face of a team member. The vital aggressiveness can soon become bogged down to a slow grind. Recognizing this, weapons have evolved to adapt to the new situation. The extremely confined nature of the urban environment necessitates the use of small, compact weaponry to allow operators to easily maneuver around obstacles while keeping the all important momentum in their favor. These shorter weapons come with their own disadvantages that need to be mitigated.
Though many of us will never be placed in an urban jungle, playing a deadly game of cat and mouse with enemy a skilled enemy, Primary Weapons System’s CQB 30 is nevertheless shockingly practical for the consumer. The military application is not far from a common civilian necessity: home defense. Already designed for a severely restricted environment, the CQB 30 is perfect for home defense for the very same reasons it excels clearing rooms. Few realize the absolutely defining noise firearms make inside closed areas, especially with short barreled rifles (SBRs). Combine the noise with the blinding three foot flames exploding out of your rifle, and you will be lucky to see or hear anything after the first few rounds. These troubles are especially evident with smaller weapons like AR15 pistols or SBRs. The CQB 30 Compensator eliminates both of these problems by redirecting the muzzle blast forward, away from your ear drums, and suppressing the flash. It also slightly delays the gas expulsion, which results in less recoil. In essence, the PWS CQB allows the shooter to maintain his focus on the target, without being distracted or disoriented by excessively loud concussive blasts or bright muzzle flashes, giving you the control of the situation and preventing unnecessary harm to a family member who would have otherwise been hit by the blast. This directly translates to greater personal preparedness and a massive advantage for the gun owner in a home defense situation.
Adapted from the PWS CQB 556, which serves the smaller .223 caliber, the CQB 30 was tailored to 7.62mm bullets, which can support 7.62x51mm (.308), 7.62×39 and .300 Blackout as long as they have 5/8×24 threads on the barrel. Weighing in at a solid 7.2 oz, the CQB is made from high quality materials which are covered by a lifetime warranty. This added weight gives the operator increased control, mitigating the difficulty many experience controlling SBRs, on top of the obvious benefits of redirecting the concussive blast and suppressing the flash. Furthermore, the PWS CQB 30 is only two and a half inches long, perfect for shorter barrel lengths for which it was designed. For these reasons, the Primary Weapons System CQB 30 is rapidly becoming one of the most popular compensators on the market today. Perfect for AR pistols and SBRs but also providing significant advantages to longer barreled carbines as well. Overall, the Primary Weapons System CQB 30 is an amazing piece of hardware with invaluable benefits to both the firearms enthusiast and home defense minded shooter and is highly recommended.
