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.

Details

The Allen Engineering AEM5 is the direct fit replacement for your MK12 SPR. The AEM5 attaches to the weapon via a mount (not included) and a collar that goes over the barrel for alignment. The suppressor mounts via threads on the outside of the mount centering on the adapter fitting. A 20 degree taper on the adapter locks the silencer onto the barrel and seals gasses inside the suppressor along with preventing the suppressor from coming loose under use.

While the AEM5 is quite long at 8.8″, it only adds 4.5″ past the end of the muzzle device.

As of October of 2022, The AEM5 has been made here in house by Trajectory Arms under license and close guidance from Allen Engineering. The AEM5 remains UNCHANGED from its original design in order to carry on the legacy of the Ops Inc 12th Model/Allen Engineering AEM5.

When mounting your AEM5, it should turn onto the mount between 7-10 turns. As with all suppressors, we strongly suggest checking alignment of your suppressor with an alignment rod before use, regardless of which mount you choose to use.

Due to the nature of the over-the-barrel design, the AEM5 needs a minimum of 2.5″ from the end of the barrel to the start of the taper collar. Generally, you will need a minimum of a 12.5″ Carbine gas or 14.5″ Mid gas barrel in order to have enough room for the suppressor to mount up.
