PRE-ORDER Guidance

As you are probably aware, recent updates to ATF's eForm approval process has resulted in drastically improved turnaround times. While this is certainly a positive change, it has also had a predictable impact on suppressor inventory across the industry.

 

With that in mind, if you know you want a particular suppressor (or three) and it isn't in stock, your best bet is to place a "PRE-ORDER" so that we can purchase your desired suppressor the moment it becomes available from our distributors.  If you wait until it shows in-stock on the website, you might miss your opportunity.  PRE-ORDER helps us seek out and purchase what you are looking for.  This is true whether you buy from us or someone else.

Thank you for considering Longbow Arms, we hope to earn your business.

*NOTE*

1/2x28: Indexes off the barrel shoulder. For use on standard, sub compact, compact, and full-size tilt-barrel firearms that have a normal profile of barrel (G19, G17, P320, S&W M&P 2.0).

1/2x28 Special: Indexes off the face of the muzzle. For use on micro compact tilt barrel firearms with little to no barrel shoulder due to the thinner profile of the barrel (G43, G43x, G48, P365, P365XL, Hellcat).

If you are concerned about fitment, the 1/2x28 special will work on a normal profile barrel as well. It will operate the same, but if you have a longer threaded surface on your barrel, you may see uncovered threads rearward of the muzzle device when using this option.

1/2x28 SMG/PCC: Made specifically for SMG’s and PCC’s (Sub Machine Guns and Pistol Caliber Carbines) that have the industry standard length of threads commonly found on carbines: 0.625.”

Glock Gen 4 or Gen 5 users: It is reported the barrel adapter may touch your guide rod when the slide reciprocates. We have not been able to replicate in house using CAM-LOK®/EZ-LOK™ barrel adapters with Glock Gen 4/5 recoil spring assemblies. However, the items below allow your Glock® Gen 4/5 to work with a Glock® Gen 3 recoil spring assembly that does not have this reported issue.

Installation & Use Notes : Suppressor should be tightly assembled when using this product to avoid inadvertent disassembly of the suppressor when removing it from barrel adapter. Barrel adapters should be installed to their host firearms with a minimum torque rating of 22 ft/lbs using a 3/4 socket and needle type torque wrench. Use of a box end wrench will not have optimal contact with the wrench flat geometry on the adapter and may damage the adapter.

CAM-LOK® requires suppressor attachment with minimum 22inch lbs of force. EZ-LOK™ requires suppressor attachment with minimum 13.75inch lbs of force. With both systems, a slight squish should be felt during tightening and indicates tapers are engaged (locked), and required installation torque has been met.

For the fastest system, choose CAM-LOK®. For the the most simple system, choose EZ-LOK™.
