C.A.M.
While other manufacturer's products result in the separation of upper and lower receivers in an effort to improve receiver fitment, the MSRx Corrective Adjustment Mechanism (CAM) rear takedown pins actually bring uppers and lowers together, as meant to be. Whether your upper/lower fitment is sloppy loose, or so tight you need a hammer to seat the takedown pin, there is a CAM for you.
Tite-Fix RTP
While most AR receiver sets suffer from a loose fitment, there are some combinations that are so tight that it requires significant force to seat the takedown pin. The Tite-Fix rear takedown pin eliminates the need for the hammer, and is a bit more affordable than the CAM pins.
Dead Blow
Bolt bounce is a legitimate concern in blowback PCC's, for which deadblow buffers have proven effective. Utilizing either lead or tungsten shot, we offer buffers in all typical configurations as well as MSRx originals.
Hard Cast
If you need to add buffer weight, but the cost of tungsten has you scratching your head, there is an alternative. Our hard cast (90/6/4) alloy is 50% heavier than steel, but at less than a 10th of the cost of tungsten. With a 20+ bhn brinell rating it is certainly up to the task. We also offer PCC bolt weights, sized to accommodate FRS and SS devices.
B.Y.O.B.
The MSRx online store maintains an inventory of various buffer weights; hard cast, tungsten, steel; so you can mix and match to achieve your desired "sliding" buffer weight, as well as pre-measured quantities of both lead and tungsten shot for building loose fill dead blow buffers.
Parts and Tools
The MSRx online store contains many small parts and tools that are germain to our mission.
Bag Bumpers
We love the discrete tactical AR soft cases, such as the those by Bulldog and MidwayUSA, but there is a drawback. If you like to pack two uppers in the same compartment, or additonal gear in the same space as the upper receiver, there is little to nothing to protect your stuff from contact. Enter the MSRx Bag Bumpers.
