3 Prong is the only one on sale- Regular Price $22 on sale for $17
The first Model AR15 (Model 601) had what is often called a "Duck Bill" Flash Suppressor. It was the only real Flash Suppressor available in Vietnam from the introduction of the Colt model 601 in 1960, until about 1962/63 when replaced with the reinforced "3 Prong" with which we are all familiar.
The Duck Bill is appropriate for models: 601, early model 602 and 607 variants.
3 Prong was much more widely deployed (1963-1967) and can basically be used on any variant in the Vietnam War since so many were already in country by 1968.
"Banned States" 3 prong has fake slots on the side (cosmetic only) and will pass the "Pinky Test" in states where this is necessary.
Made in the USA. Steel. Both are authentic reproductions of the original.
For washer selection (Here). For these we recommend using the lock washer.
Like it. Gave it 5 freaking stars
Awesome this will be the perfect finish to my build
Great looking flash hider, looks just like the one that was on my M16 in Vietnam.
Fits great. Exactly what I was looking for for my M16 clone. Fast shipping, as well.
This was a very good deal and you can tell as me to have a good American Steel fit the rifle perfectly the only problem is you have to be very careful putting it on and not been the prongs and Marr it up.
