Vietnam-style AR-15

I have a reproduction waffle mag from NDS(shell only) you need to provide your spring/plate/follower. Runs 100%.....If you want to go that extra step on your retro

Kimberkid....nice

Nice. We used to call that flash hider the "twig snatcher." Walk through the woods with one at the ready and see what happens.

 

[ifit]

Ah yes.....the evolution of the muzzle breaks on the ar, but I don't plan on walking through the woods at the ready with mine, I have much better firearms this time and age for that purpose

 

[moxie]

Well, that 3 prong device is a flash hider, not a muzzle brake. It was effective, but did tend to hang up on twigs and such. Hence the switch to the A2-style "birdcage" flash hider, that does double duty as a compensator. But still no muzzle brakes, evolved or otherwise. AR15 muzzle brakes are specialty aftermarket items.

Good to know...,thanks for the correction

Isn't a muzzle brake's sole function to reduce recoil by using a bunch of holes to port the gas out with the tradeoff being added noise?

Two questions...
1. Why would you need this on a 5.56?
2. Since the rifle is gas operated, wouldn't the remaining gasses at the brake be minimal at that point anyways?

So why would you want a muzzle brake on an AR-15 again?

I get the flash-hider... that makes sense in combat conditions.

Yes, a muzzle brake reduces recoil.

You do not need a muzzle brake on a 5.56 AR type rifle. Rifles like the AR15 only have a flash hider.

There are a number of designs for gas operated rifles. The original AR design uses a DI (Direct Impingement) design. There are also a few Piston designs out there.

Keep in mind only a small portion of the gas is used to operate or cycle the rifle. Also, yes, where the gas is bled off in an AR design the pressure is relatively low as compared to for example directly forward of the chamber.

So as mentioned, on an AR the device at the end of the barrel is a "Flash Hider" be it pronged or bird cage type design, it's a flash hider. See Moxie's post #29.

Right and I was referencing/questioning the viability of aftermarket muzzle brakes for AR15s at the end of that quote (#29).

Thanks for the clarifications though on my assumptions.

Does anyone have pics of them with their M-16s in Vietnam?

 

[kimberkid]

I've got a few pictures a friend shared with me ... I have a few of him with his M16 but not on this computer, plus I'd want to get his permission since he's in them ... I'm sure these would be ok though;

I've built several retros .. no dak spud... good stuff.
retro black rifle will help alot.

The only thing I changed out on my vintage AR-15 was the triangular handguards. Could never get comfortable with them and swapped them out with a round pair as soon as they hit the market.

 

[Reloadron]

I guess if I wanted a rifle along the lines of the Vietnam era I would just go find a Colt SP1 and let it go at that. As to the handguards, I wouldn't change them as the rifles I have memories of had the triangular handguards.
