Info on Adding Muzzle-Brake to SAR-1

Bullzeye

I'm looking to add a muzzle brake to my SAR-1.

The two types I've seen are the AK-74 type, and the cut-top type. Based on what people have told me, the cut-type brakes are far more suitable for the higher muzzle climb encountered in rapid fire with the 7.62x39, as opposed to the smaller climb in the 5.54.

So, my questions are:

If I get a pin-on type, what's the process for drilling to hole to put the blind pin in? I dont want to destroy the barrel.

If I get a threaded type, what's the process for drilling out the threads so I can attach it to a non-threaded barrel like on my SAR-1?

My ultimate goal is not to destroy the gun!

Bullz,

I put an AK-74 type brake on my SAR-1 (it was supposed to "pin-on", but did not fit right--I had to use a number of set screws).

I've fired it side-by-side with an SAR-1 without the brake; my conclusion: It's not worth the effort; any reduction in recoil and muzzle climb is really not noticable.

What I did do which is really nice and well worth the work, is to add a few inches to the butt-stock along with a rubber recoil pad. The standard stock is made for the "average world man"--who is quite a few inches shorter than the "average American man". Arm length is proportional to height; two to three inches on the stock adds comfort if you have the height.

What you'll find is that the majority of the add-on muzzle brakes have been designed to fit on the Norinco MAK90 or the Egyptian Maadi rifles. The front sight assembly on the SAR-1 is different, hence the pin is in a different place and would not attach the way it was designed. This has been a common problem. Many of the accessories available on the market were designed for the guns available at the time. If the current imports are in any way different, problems result. The same holds true with SKS accessories. Many of the accessories for the SKS were originally made for the Chinese SKS. The Russians and Romanians had similar tolerances, so there were little or no problems with interchangeability. The currently available Yugoslav SKS's have several differences from their counter-parts, hence there are a number of these currently available accessories that will not fit the Yugoslav SKS's. Stocks for example will not interchange without modification.

The kick doesnt bother me at all. It's the muzzle flip which makes it nigh-near impossible to aim properly at anything remotely approaching rapid fire.

Hmmmmmmmmm. I have "bump fired" my Chinese MAK 90 at 10 rounds per second with a AK 74 pin on muzzle brake and it seems to help reduce the jump although the firearm is still very inaccurate at that rate of fire.
I like my pin on AK 74 muzzle brake, it looks nice if nothing else.
At a standard semi-auto rate of , say, one round fired every 1 or 2 seconds I notice no muzzle jump with the AK 74 brakes installed.

I would find a quality muzzle break, I know they do make them, but they usually have to be professionally installed by a gunsmith, usually sivler soldered or something.

But my advice is, that if it doesn't have to be fitted or done by a gunsmith, then it probably won't work for crap. Thats why I'm always weary of anything that say "Drop-In" that wasn't made by the manufacturer.

If I'm wrong please correct me, I won't be offended.
