My featureless solution MAS 49/56

[Bainter1212]

OK so Calguns won't let me update my old thread, so here goes....

I finally managed to snag a rare type 2 muzzle brake for my MAS 49/56, which eliminates the "flash hider" problem.

The only thing left was to neuter the grenade launcher function.

I did that by sandwiching a heavy steel spring washer between the locking ring and the lock washer. There is still some wave to the washer, although I tightened the locking ring TIGHT with a hammer and brass punch. This sucker ain't going anywhere anytime soon.

Now a grenade cannot fit over the device enough to be useable.

A friend of mine suggested this method, please let me know if you guys think it is enough.

I know it is not easy to just find a type 2 muzzle brake.....I haunt the Gunboards Trader like a parasitic remora, and just happened to be there when somebody listed this one for $50. However, it does prove that they are out there, you just need to be vigilant.

BTW.....if any enterprising machinist wants to borrow the muzzle brake and make a run of exact copies....I am sure some folks on here would buy. Especially if it was slightly larger in diameter to avoid the whole washer thing.

Wont deter a bad cop from removing it if he really wants a conviction.

Well done.

The hoops we have to go through...........

True...althougb I now have it documented, and it ain't gonna come off easy at all.

I know. I hate this state. My wife and I are looking at property in Montana. The first thing I will do once I move is to buy a gun in a parking lot.

Why even buy the gun then? If you don't get one, a bad cop won't get a conviction.

[OniKoroshi]

I hate you! I've been looking for one for a long time! Lol

[pitfighter]

It is a good thing you did that, as the 22mm NATO standard rifle spec grenades are so easy to come by.

Great idea though - I would probably drop a single tack-weld (or braze) onto the space between brake and washer, too -

Stop with the anti LEO bias...A "conviction" or an arrest would not be possible...

Your post is silly. No LEO is going to remove his washer...

Here is the muzzle end of my Mas49/56 this one is re chambered in .308 and has shot 100 rounds flawlessly!!! And let me tell you Bainter its funny seeing you posting because you were 2nd in line on my Mas49/56 I just bought and sorry to say you missed a good one but you have got many before me in this market place. So far so good nice seeing you got one. Nice to know there are other collectors around. For me I love semi auto C&R's I am 20 years old and cannot get enough! I need an SVT40, and Remington 81 now.

Nicely done Bainter, it looks good with the muzzle brake. I'm glad you were able to find an original one.

Only catch is that the grenade launcher is a banned destructive device in CA; it's not a banned "feature" - meaning possession is a problem. The large washer does not rectify the problem, and you would be best to do away with the lock-ring entirely, in lieu of the washer.

With that said, I'm also a realist; the likelihood that most any DOJ rep, LEO, or even a prolific gun owner of more common guns (i.e., not C&R) would even know what in the hell they are looking at to then also know what it is, let alone to know the laws banning grenade launchers exist to cognate it's an evil, inanimate object would be rare.

Many people remove the sights too, but as I've stated elsewhere, I don't see the sights as part of the device itself; to me, the lock ring is solely the device; otherwise, one could say the barrel is part of the device because it has the notches. I've taken to leaving the GL sights on.

And the Fench MAS 49/56 just looks weird without the GL sights. Sans lock ring, not as weird.

Don't forget the Winchester 1907 -

At the risk of offending the purists, it's easy as heck to rethread the MAS 49/56 muzzle to 5/8X24 TPI and then attach any AR 10 type brake you prefer. With hand die and pilot it took me about 15 minutes. Since the 7.5 bore is just a tad under .308 the most time consuming part is dressing down the pilot to drop into the bore. I use an Armalite 2 chamber brake that looks "period correct" on the MAS 49/56 and will not allow a grenade to slip over.

I think on a technical review the gas shut off and flash suppressor diameter are bigger problems than the range ring for the GL issue. I went with making the diameter of the FH too large to fit a NATO grenade. With the DOJ mindset, if they could launch a dummy grenade from even a reduced diameter device to any distance they would probably consider the rifle equipped with a GL. But, they would be the determination of that.

Hahaha......that is perfect.
