M14 muzzle devices.

Decisions on what muzzle device to install on an M14 can be more than confusing. Each time I nail a new rifle together, the question of what to put on the barrel to protect the crown arises. There all sorts of rave reviews, for many devices and how they enhance accuracy to the point of being overwhelming. Most do a fine job of protecting the most important muzzle crown, but I personally have yet to see one that will do much to improve accuracy. Some do a better job than others as far as reducing recoil, but that's about it.
What I am looking for is input from shooters that have actually documented results using flash suppressors and muzzle brakes other than the cool factor that seems to be the most appealing to the majority.

These are a few that I have used.









The of coarse there is the no cost option that I still think provides the best accuracy without the crown protection.


Thanks from unkola and JEFFJP_N_JJ

Thanks Art I will be watching this thread.
I just got me a VG6 Epsilon 762 to try on one of my rifles but need to decide which adapter to buy for it and was thinking which would be more accurate:
The straight one or the one held on by the castle nut?

The VG6 Epsilon 762 in my top photo is attached with an SEI adapter.
Really Jeff, thanks for the interest. That's the reason for the thread. We all have questions and the marketing hype is so confusing. I know there are a few like RAMMAC that have tested more of these critters.

What I have learned over the years...

The front end of the M14 was designed to be easily taken apart for cleaning and replacement. Accuracy doesn't appear to have been a consideration.

Ball powder makes use of a flash hider, stick powder really doesn't need one, especially from a 22" barrel.

The bottom of the device needs to be solid. It keeps the muzzle down and reduces dust when prone.

Howitzer like side ports aren't needed for 7.62x52 gas gun. They divert the sound and gas back to the shooter and those next to him.

Top ports, like the M1A Socomc, keep the muzzle down for follow up shots.

If a brake is desired, the linear style work great, especially in close quarters. All the gas and noise is directed towards the target.

My idea of an ideal M14 muzzle device would be the SEI National Match, with just the top ports. No side openings.

I've used both the SEI compliant sight base and the NM brake. Both were accurate.

I am wanting to decide between the SEI muzzle adaptor or the one with the castle nut and front sight mount I do not need with a Bula XM-21 reciever?

Cannot remember what the rifle I bought from Johnb2488 has on it... If I can find some time hope to pick it up tomorrow

Here is a photo of Grizzly Gun Works model 7.62. Upper photo is the top view and lower is bottom. Both brakes are the same size. Photo creates an illusion.

I don’t have any photos of the various devices I’ve tried but I would say the best I’ve got is the SEI coast guard. It really keeps the flip in check and allows for quick follow ups shooting offhand.

The Good Iron (LRB??) worked great but was so loud I got rid of it. It scared fellow shooters at the range. Looked pretty tough though.

SAI’s Socom brake worked well enough but the fat front sight sucked eggs so I switched over to SEI adapter and their vortex flash hider. Love it.

SAI’s longer brake they put on Scouts is comparable to SEI and I suppose a little less expensive.

All things considered I still like the look of a good old fashioned lugged flash suppressor the best. Plus, I can “put a knife on it!” (Quoting Boy at age 9).

I don't recall any one saying that a Brake , Compensator or Flash Suppressor will help in accuracy , except on quick follow up shots or reducing recoil for keeping scope sight picture. At least I don't recall any saying or printing that in a brochure .

The proven best accuracy from a Barrel is with some sort of match Muzzle Crown with out any Muzzle device . Not saying a Barrel with a Muzzle device cant be accurate , but I think it can hinder a Barrels performance .

As I has said before , if you're at a gun range , you should be using ear protection , so a Brake shouldn't be an issue next to you .

Would that shorter SEI flash hider(top left of first post)work with the GLFS on a Scout like the one on the right or is that for the Socom? I bought a vortex off a forum member and will be installing with the hooded gas lock, but if I could find a shorter one I'd like to try that as well.

Also, if anyone is interested; I have a gas forwarding or Linear comp on a short .30 cal bolt gun and I can definitely attest to its efficacy in redirecting the noise away from the shooter. It really seems to do something. I'd like to try one on my Scout. Anyone know one that will direct thread on a SA barrel?

Thanks.

I have very little to contribute as far as controlled testing. Whatever I put on a rifle tends to just live there, and if I change stuff, I haven't documented differences.

I can say that while I have noticed differences between a linear compensator and a brake, in terms of both noise and muzzle rise, I really haven't noticed anything, as a shooter, the way I tend to shoot, that is outside my range of acceptable. I've also never experienced anything that actually removes muzzle movement. I expect that this might have something to do with the variability of factors that contribute to muzzle movement, the geometry of the stock, how it's mounted, weight distribution, whatever. I know there are devices that are tuneable, which make sense if you want to dial it in, but I'm not that motivated to explore.

I'm definitely interested in results, in that it's cool to explore, learn, and tinker, but for me, selecting a muzzle device is as much a matter of trying something to fill out a concept and aesthetics, with some degree of functionality, at least theoretically as it fits that concept, but in what I've tried, USCG, Witt Machine Brake/Linear compensator, SAI brake, SEI 'Good Iron' pseudo 'Vortex' brake, JP enterprises Recoil Eliminator, JP large brake, I cannot say that any of them actually jumped out at me at overwhelmingly better or worse than any others. I am sure that if you did direct comparisons on the same rifles, and measurements, there would be differences. I have seen some very cool objective tests done on a wide variety of brakes, most of which aren't any I've owned, which characterized recoil reduction as well as sound changes to the side and behind the rifle. If given the information, I'd sure consider it.

However, in practice, I haven't noticed anything in what I have that for a casual user like me, who doesn't do controlled testing, or for that matter have a priority on coming back to shoot the same target repeatedly, quickly, with a much of any precision, let alone well enough to look awesome on a tactical youtube channel, when mixed in with other variables, that stands out as clearly better than another. Slight differences, sure. Characteristics that may be preferred for an application? Sure. Night and Day? Not at all.

If a muzzle device did in fact make a rifle more accurate, and I suppose it is possible, in individual cases, I would guess that it probably because it happened to fall favorably, and by luck, into the 'Voodoo' variable pot as far as tuning the barrel whip to work out with a particular load, and that you could get the same benefit by changing the load, or tweaking the draw pressure of the stock, or whatever, but I know nothing certain or factual in this regard.

Thanks from vanvock

I have used the national match flash hider, the older Vg6 epsilon and the newer version of the precision epsilon 7.62. The precision exhibited a little tighter groups among the three. The biggest difference was reduced muzzle flip and recoil mitigation. I have targets of the three different FH’s I will have to dig them out.

No, the shorter one works with an adapter. The longer one, the direct connect, is required to cover the muzzle splines.
