Brownells XM16E1 3 Prong Flash Hider, .22 Cal, 1/2-28, Steel Black

Description

The Brownells XM16E1 3 Prong Flash Hider is a faithful reproduction of the Improved three prong muzzle device that replaced the early duckbill flash hider on Vietnam-era rifles. The original duckbill design had thin prongs that tended to bend and break in the field, so the military moved to this reinforced version. Brownells modeled this part directly off the original, making it the correct choice for Model 602 and 603 rifles as well as XM16E1 reproduction builds.

Machined from steel with a black phosphate finish, this flash hider threads onto standard 1/2-28 muzzle threads and is sized for .22 caliber bores (.223/.224), so it works on most 5.56 NATO and .223 Remington AR-15 barrels. Beyond retro clone builds, it looks right at home on any AR-15 where you want a distinctive period-correct profile that stands apart from the common A2 birdcage.

True to the original design, this muzzle device does not have wrench flats. Plan on using a strap wrench or a 3 prong armorer's wrench for proper installation. A crush washer is not included, so pick one up separately if your build calls for timing or indexing the device.

This flash hider is a natural fit for retro rifle enthusiasts recreating an XM16E1, Colt Model 602, or Model 603, as well as historical collectors and AR builders who appreciate Vietnam-era styling. Owner feedback on this part has been strongly positive, with buyers praising its accurate dimensions and authentic look on clone builds.

Before ordering, check your state and local regulations regarding muzzle devices, as some jurisdictions restrict flash hiders. With its reinforced prongs, durable steel construction, and dimensions taken straight from the original military part, the Brownells XM16E1 3 Prong Flash Hider delivers the authentic details that make a retro build complete.

Frequently Asked Questions

Does this flash hider come with a crush washer?

No, a crush washer is not included with this flash hider. If your installation requires timing or indexing the device, you will need to purchase a crush washer separately. Many builders going for period-correct looks install it without one, matching the original configuration.

How do I install it if there are no wrench flats?

Like the original military part, this flash hider has no wrench flats. Brownells recommends using a strap wrench or a 3 prong armorer's wrench for proper installation. Avoid using pliers or pipe wrenches directly on the prongs, as that can mar the finish or damage the device.

Will this fit my AR-15 barrel?

Yes, as long as your barrel has standard 1/2-28 muzzle threads, which are typical on 5.56 NATO and .223 Remington AR-15 barrels. The bore is sized for .22 caliber projectiles (.223/.224). It is not intended for .30 caliber or 9mm barrels.

What is the difference between this and the early duckbill 3 prong flash hider?

The early duckbill 3 prong flash hider had thin prongs that tended to bend and break, which led the military to discontinue it. This Improved version features reinforced prongs for better durability while keeping the classic three prong silhouette. It is the correct style for the XM16E1 and Colt Model 602 and 603 rifles.

Is this an authentic reproduction for retro clone builds?

Yes, Brownells modeled this flash hider directly off the original part used on rifles issued to the US military during the Vietnam War. It is the proper muzzle device for XM16E1, Model 602, and Model 603 reproduction builds. It also looks great on any modern AR-15 where you want a retro touch.
