DOWNLOAD BROCHURE AND INSTRUCTIONS Installation & Tuning CWS™ installation is simple, but please view all the instructions carefully, as there are special compensations necessary for assembly-disassembly and adjustment of the CWS™-equipped rifle. The CWS™ is designed to be a "slip fit" into the rear of an AR15-type bolt carrier. As such, installation into the carrier itself is simple: just drop it in. The CWS™ is trapped by the buffer spring and cannot shift or loosen. c 1. Separate receivers and drop in CWS Normally, accessing the bolt carrier in an AR15-type rifle requires only sliding the rear receiver takedown pin outward and lifting the rear of the upper receiver. To install CWS™ you must also slide the front takedown pin clear so that the entire upper receiver assembly can be separated from the lower receiver assembly. [On a Colt®, or other rifle equipped with front pin screws, the screws must be removed.]   2. Position upper receiver forward of pin holes The CWS™ flange creates the only complication in assembly since it is normally not possible to close the receivers without separating the front and rear pins. The flange on the CWS™ requires sliding the upper receiver straight back into alignment with the takedown pin holes. . After installing the CWS™ in the bolt carrier, reassemble the rifle by situating the upper assembly so that the corresponding takedown pin hole in the upper receiver is approximately one quarter inch forward of the rear takedown pin. x 3. Slide upper receiver straight back to align holes Engage the CWS™ with the buffer assembly and slide the upper assembly straight to the rear until the takedown pin holes align (4). The CWS™ will meet resistance from the buffer spring. x 4. Engage front pin Insert or reinstall the front takedown pin to trap the receiver in place. x 5. Engage rear pin Close the rear takedown pin and check for function by cycling the carrier a few times and dry firing. x 6. Check overrun Locate the bolt stop and retract the bolt carrier fully. (This is easiest done with an empty magazine in place.) Fully retracted, there should be a gap of approximately 1/16 inch (the thickness of a dime) between the bolt face and the bolt stop. If the gap is much less than that, the bolt stop may not have time to fully extend prior to the bolt contacting it on the forward return of the carrier. . If this gap space is inadequate, disassemble the buffer and spring assembly and remove material from the rearwardmost polymer surface of the buffer. A belt sander is recommended for this job. x Installation trouble Notice the burr on the inside edge. This is on a new Colt carrier and did not interfere with installation of CWS. CWS™ has been carefully engineered to work with a wide variety of bolt carriers. However, there may be an occasional bolt carrier that, due to its machining, may need to have additional metal removed from its surfaces. This has nothing to do with the CWS™. All that is normally required is a careful examination of where the interference occurs and then relieving the obstruction. Normally, this interference comes from the inside edges of the open area on the bottom of the bolt carrier. We recommend (careful) use of a rotary grinding tool or a flat file. Do not remove metal from the CWS™! x FUNCTION PROBLEMS CWS™ was tested and intended to operate in conjunction with the SpeedLock™ CS AR15 Buffer Spring. This is the only spring engineered specifically to handle the increased demands of High Power Rifle competition. It is constructed from Chrome Silicon alloy, a radically superior material to the common music wire construction found in all others. Due to the superior nature of its material, our CS spring has the same power as a conventionally constructed "extra power" spring, yet provide that extra energy using a lighter spring weight. Correct timing and resistance on the recoil stroke and a controlled rebound ensures reliable feeding with consistent forward thrust. The CS Spring enhances the effect of the CWS™-equipped rifle in two ways. Resistance to unlocking is increased, thereby further influencing this aspect of CWS™. And the opportunity to realize reliable function with the CWS™ at maximum weight is also enhanced. This combination makes a big difference! We have found that the addition of the SpeedLock CS AR15 Buffer Spring eliminates a majority of malfunctions in rifles used for High Power competition, whether CWS is installed or not. x TUNING CWS There are two accessory weight inserts packaged with your CWS™. One is stainless steel, one is carbide. The CWS™ itself, with no additional weight inserts, weighs 1.54 ounces. The CWS™ with the stainless insert weighs 2.79 ounces (1.25 insert weight) and the CWS™ with the carbide insert weighs 4.05 ounces (2.51 insert weight). Due to shooter preference, ammunition, and original carrier configuration, it may or may not be possible to use the maximum weight combination. Some carriers are designed utilizing more metal in their structure. We have never had a rifle, regardless of carrier brand, that wouldn't function with the CWS™ alone. For the competitive shooter, we recommend starting at the top. Install the carbide insert and test fire the rifle. Make sure to check its function with the lightest load you will fire through the rifle, magazine fed, and also check its function firing rounds from the standing position. The carbide insert provides the maximum benefit to the pressure sensitive heavy bullet loads common in High Power competition. Otherwise, experiment with weight variables to your satisfaction. Some shooters may prefer a quicker cycling action or find that the carbide insert doesn't always function 100-percent with some lighter loads they may use.
