i'm in the middle of a dolling up an sks d [reworking an ati druganov stock ,bedding the receiver nice and tight ,tightening up trigger group lock and scope mount] ordered a red dot to mount on this.the end result i hope will be a handy quick target acquesition carbine particulary usefull from 75 yards in . i am now looking for a muzzle break to help with rapid shots. i see there are a few clip on mb's out there and am looking for some advice with these.what do you use and what is effective in controling muzzle jump? if some of you are using a thread on mb ,what is it and how does it work for you? this rifle is a norc d model, so i would need to thread barrel.controling the muzzle i would say is more important to me than any noticed accuacy improvement.give me your thoughts please.

I did not have a muzzle brake on my SKS and so far what I heard from some other guys who have one installed(non thread) said it might get loosen very easily. I guess if you are able to thread the barrel and find a suitable thread muzzle brake, it should be perfect.
 
I had one that was held by a set screw. It came off and ended up some where down range...never did find it.

Actually, I find you don't need one with a good sling hold.

It ain't a 308 :)
 
For the Loctite to work, that muzzle brake will have to be machined very tight.
IF you really intend to modify that SKS beyond recognition, you could regain some barrel length up front by setting the front sight back a bit.
You'll have to drive out the two pins that hold the bayonet/sight sleeve then get that sleeve out by placing a wooden block behind the rear sight boss and tapping it out.102. A prolonged soaking session in a jar of penetrating oil such as Kroil will do wonders.
Now, you'll have all the necessary space for a real flashhider and/or compensator to be threaded in place.
If you still want to retain a front sight (sometimes it comes in handy), then you'll have to shorten the rear part of that bayonet/sight sleeve and reinsert that sight assembly on the barrel.
Now, it is possible that the pin keyway won't be at the same place so you'll have to file a new one once you mark the sight's final position. Be careful to set a true vertical position for the front post.
Have fun!

None of the aftermarket muzzle brakes I've seen available for SKS's are designed properly, I'm 100% certain that even if they do work, they'll only work a fraction as good as a properly designed muzzle brake. The volume and velocity of gas coming out of the muzzle is more than enough to snap those little pins or straighten the little locking arms on the removable style brakes. Check SKSboards.com, some guy just sent his bolt-on muzzle brake downrange not too long ago (he posted pics, too).

If you want a muzzle brake that looks cool AND works, there are none available, your only option is to 1) make one yourself or 2) get one made at a machine shop. There's a guy in the US (www.ricksmuzzlebrakesandgunstuff.com) who makes muzzle brakes for M59's to replace the grenade launcher, but you should be able to get it done at any machine shop, and to whatever specs you want. Muzzle brakes also make more noise and more flash, not less, so be prepared for that as well :D
 
There is enough material on the end of the barrel on the SKS to thread for a muzzlebrake without setting back the front sight. This is a brake I made and it is threaded on and has not moved in over 400 shots, I have also made three more that have seen over 1000 rounds without moving/coming off.

Here is a pin on brake with 2000+ rounds through it. It was VERY tight to put on; the machining and finish are excellent. It makes a huge difference to recoil and muzzle jump, the down side is the increased noise to the shooter and anyone directly beside you!



Edit for bad spelling

Nice work, she looks great. :)
 
They look cool, but I don't notice much recoil or muzzle jump with mine. Are these things really necessary? Or are you all just little girly-men?... :rolleyes: :p

edit: And those Dragunov stocks look great, too but are very uncomfortable for me, especially the cheekpiece. Ugh! I prefer the original spec stock.

mudpuppy:nice work,you must have access to a lathe.what threads did you use and did you have to turn the barrel down a few thou for threading? holleyman: i thought the pins ons would be much better than the set screw types,which one is that by the way? girly men?no,the sks doesn't jump that much,i know.i'm looking for quick target acquesition under rapid fire,and hey ,lets not forget the ###Y FACTOR.

When...I get my SKS I don't think I'm going to put a brake on mine...they sound too loud IMHO (even with earplugs on), and seem too problematic.

Glad I passed on buying an SKS muzzle break at the local Gunshow last weekend...$38.00 bucks better spent elsewhere. :)

It is the pin on type, got it from P&D in Edmonton. It was very tight going over the muzzle. I put Loctite 609 on the muzzle and the brake to keep the metal from galling and also to aid in retaining the brake plus the longer pin through the sight. I don't think I could get it off if I wanted to! You'll like it when you get one.
 
Muzzle brakes, when they work, will dramatically reduce muzzle flip. If yours doesn't, it means there's something wrong with the design. What does it look like? Holleyman's muzzle brake is one of the AK-74 design copies (which is, incidentally, actually a flash hider), the example that I saw & handled had some design inconsistencies that would have reduced its effectiveness. Mudpuppy's brake is awesome, not only does it look wicked but the massive horizontal vent holes will stabilize the muzzle a helluva lot more than the pin-on AK-74 design. Kinda like this brake (widely acknowledged as the most effective brake on the market);

This next brake is ideal (although ugly as sin). It looks like a typical tank cannon style brake, and you know those things gotta work otherwise they wouldn't have 'em on a bloody tank, right?

This brake would also work fairly well;

And this one would not, looks like another flash hider to me that's been mistakenly billed as a brake;

Basically, I forgot the point that I was trying to make, so I'll shut up now :D

Yeah the OD of the barrel has to be turned down a hair and then I threaded it 7/16-20.

This a project gun to see what I can do with an SKS. My M-14's are already modded and I can't take the FN's out so I figgured why not play with the SKS. I am going to remove material from the brake in small increments until I find the "sweet spot" for the barrel, somewhat like tuning with the BOSS system. It will already hold under 1.5" at 100 yards for 5 shots with the Norinco silverbox and I will start on handloads soon.
 
sks

I never thought of putting a muzzle brake on an sks, but I would never own one so its not an issue.:p A .458 with a muzzle brake makes sense but on a 7.62x39.????
What next, a muzzle brake on a pellet gun ???:eek:

Actually, you meathead, a .458 with a muzzle brake makes absolutely no sense at all. Big boomers with low gas pressure at the muzzle like .458's, .444's, .450 Marlin, 45-70's and shotguns benefit the least from muzzle brakes. Ever seen a brake on a 45-70? Didn't think so. Smaller calibers with lots of powder behind them (and resulting high muzzle pressure) will benefit the most, like .220 Swift, .22-250, 25-06, etc.

Has to do with F=Pa (Force=Pressure x Area), the whole point of a muzzle brake being to re-vector Forces on the muzzle to cancel out movement, including recoil. The more force there is, the more effective the brake, therefore smaller calibers (small bore/muzzle Area) with lots of powder (lots of Pressure) will benefit the most.
