AE – AEM4 FDE Package (Can + Brake + C8 Collar + Shim Pack)
Complete Allen Engineering package — everything you need to run the AEM4 on your rifle:
- Allen Engineering AEM4 suppressor — FDE, 5.56mm, B-Mount (2.05″ mounting length)
- OPS/AE Brake — 1/2-28 Short (5.56)
- OPS INC C8 Short Collar
- AE Shim Pack — 1/2″
The AEM4 (Ops Inc 16th Model) shares the AEM5’s baffle section in a B-Mount can: 8.4″ overall, adds 6.2″ past the muzzle, and weighs 19.4 oz. Mounts on barrels as short as 11.5″ with a front sight base or low-profile gas block.
Compatibility: 11.5″ is the minimum barrel length for this B-Mount setup — it is not compatible with 10.3″ barrels.
Front sight post (FSP/FSB) uppers: fitting the C8 collar requires modification of the bayonet lug.
NFA item — the suppressor transfers to your FFL/SOT dealer on ATF Form 3. Price does not include shipping.
