• Batch 1 & 2 - Shipped (One can from Batch 2 is in Batch 3)

A 1:1 external replica of the most widely issued Vietnam-era suppressor, blueprinted from one of the few surviving originals. The HEL-E4A® combines historically accurate Parkerized carbon-steel construction with proprietary modern internals and provides approximately 30 decibels of sound reduction compared with an unsuppressed M16.

REVISION 3.0

Retains the Rev. 2 welded construction while introducing a stronger, original-style fixed rear cap that indexes on the front sight base to prevent loosening. Five indexing positions—compared with two on the original—provide finer alignment and generally eliminate the need for shimming, though timing shims are included for minor final adjustment.

BARREL COMPATIBILITY

Designed specifically for 20-inch and 14.5-inch, .625-inch “skinny” USGI-profile M16 barrels.

• Original USGI and current-production H&R 20-inch barrels fit correctly - Not compatible with Fulton Armory barrels or modified/nonstandard USGI-style barrels as far as we know
• Fits the 14.5-inch Colt carbine barrels included with recent Bowman kits without shims as originally thought.
• Other 14.5-inch, .625-inch pencil barrels may require fitting or timing shims. We currently recommend installation only by mechanically experienced users.
• Brownells 20-inch barrels are functional, but their threaded shoulder is approximately 1/8 inch longer than USGI specifications. This may affect rear-cap indexing on the bayonet lug. A competent gunsmith can turn the shoulder to the proper USGI dimensions if desired.
• An optional Brownells-specific rear cap will be offered separately to accommodate the extended shoulder.

INSTALLATION

1. Remove the flash hider and split washer.
2. Remove the Allen-head cap screws and washers from the suppressor.
3. Carefully slide the rear cap over the barrel and index it on the front sight base and bayonet lug.
4. Hold the rear cap in position with the back of your hand while carefully sliding the suppressor over the barrel and threading it onto the muzzle. Ensure the suppressor remains properly aligned.
5. Continue tightening until the threaded mounting holes align with the corresponding holes in the rear cap. A small amount of additional tightening may be used to achieve alignment, but do not over force it.
6. If the holes cannot be aligned, remove the suppressor, install one timing shim and repeat the installation. Add only the number of shims necessary to achieve proper alignment.
7. Reinstall the Allen-head cap screws and washers. The screw threads are designed to tighten progressively and resist backing out.
