View Full Version : WSAR-2 FSB?? COMPLETED!! AND Range tested..

September 30, 2007, 00:18
SO what front sight bases will fit on the wsar 2 so I can use an AK-74 brake? I know the romanian one from K-Var will, but it is 22mm threads, not the standard 24 mm threads. Or, better yet, where can I get a 22 mm AK74 brake?

You can find the U.S. Made 22mm front compensators here in the link,But they are not Cheap at $75.00 or at least they were a few years back as I have one on my Romanian Sar-2 http://www.ak-103.com/parts.html http://www.ak-103.com/home.html

how about which frontsight block with 24mm threads will fit? that may be better....

I got the FSB from Kvar, and the USA brake from AK-USA... will post pics when it all gets here and is put together... some more furniture comming too....

The romanian 22mm FSB.... well, it doesn't fit. too small inner Diameter to go on to barrel. SOOO.... I need to bore it out. The Navy and Marine Machine shop are nice to me so its no biggie, but damn that sucks....

The Romanian FSB for the 22mm muzzle brake will just press on a SAR-2. I'm guessing that it should just press on a WASR-2 also (but I certainly could be wrong).

What do you mean by "too small inner diameter?" Obviously, the FSB should be a tight press-on fit on it's barrel seat...

Inquiring minds want to know...

I guess the WSAR is different. Its wierd. It is FAR from being a press fit. The WSAR barrel is even stepped so the old FSB would slide on, then require force for a press fit, and it is a completely different style FSB as well. n a minute to show you. even the retaining pins are in different locations..... The only info I have found on the web has been for a SAR, not a WSAR. the SAR seems to have the 22mm threaded FSB with mods to nueter it, where as the WSAR does not.....

Looking at the inside diameters of the two different FSB's It doesnt look like there is enough material to bore out the inside diameter for a press fit to the barrel,if it was me I would have the barrel diameter reduced on a lathe so that you could press fit the Romanian FSB on to your barrel,you will probably have to remove the barrel retaining pin and press out your barrel to have the diameter reduced for the FSB.

October 15, 2007, 10:14
See, I was thinking that as a good/easy option as we have a lathe at work..... but... boring the FSB out to match the old one, will be much easier, and will draw less attention to itself. There is plenty of material on the FSB to bore. it just needs a few hundreths to be good. maybe not even that much.

BTW the US brakes are still $75. Thats the total he charged shipped.

you do know that the Romanian FSB is supposed to go all the way on to the barrel untill the end of the barrel is Flush with the front edge of the FSB where the threads are for the muzzle compensator dont you ? ,from what you are saying about boreing out the inside diameter only needing a few hundreths to be good it sounds like you were just going to mount it on the smaller diameter of the front of your barrel which would be incorrect,I guess I could have misunderstood what your were saying though....

October 15, 2007, 10:41
I know. I just need it bored out enough to go onto that stepped portion. if I bottom it out there, it ends up flush with the muzzle. if it free floats a hair on that last 1/2 inch thats fine, as the pins will be where it is in full contact of the barrel.

October 15, 2007, 10:41
Well, there certainly is a difference, isn't there...?

I'll take your word on enough metal being there on the new FSB to open it up for the barrel. From the photo, and to my eye, it looks like there isn't enough there (as Mosin Guy says...)

Personally, I'd probably pull the barrel (again, as Mosin Guy suggests) and turn down the FSB seat on the barrel. Pulling the barrel is no big job, especially if you already have a hydraulic press and whatall...

Good luck...

And, by the way, nice photos...

Thanks, but have to give crsdit to the Nikkon with the Macro turned on. Just a cool pix L3. After the old Nikkon survived desert 'nam, I figured I had an obligation to be loyal.

Pulling the barrel will be a bit of a chalenge for me, see, getting the gun into work, avoiding all the prying eyes and pressing it out, turning it and then repressing it will be a challenge. People are very gun friendly there, as I have built some guns there and what not, the big man is back from his deployment and seems to want to be overinvolved to re establish himself.There is plenty of meat left to bore, the OD is is a hair larger on the new FSB. And there is the whole " least expensive part" rule. ;)

Wish I had recorded the measurements I took. Guess I need to do that. Should have everything done tuesday.Hopefully the brake will be here soon as well.

I think you will be very happy with the New Compensator when it arrives as it is a exact copy with two chambers and chrome lined just as the original was.......

October 18, 2007, 18:16
I have finaly installed the new FSB. Looks great. it was .040 smaller than the old one, so boring was no issue. It went on tight at .574 ID and I mean TIGHT. But I got it aligned ( which makes the Gas block cant even more obvious now... thats next to fix...) And all I need are new pins and the Comp to get here. The old pins are bent and mangled, so unuseable. I do have the 2 pin holes drilled as well. So just a few more days... I will post pics when its complete.

October 21, 2007, 19:13
After reading that the gas block is .575, .574 being tight makes sense. I couldn't wait for new pins and my holes were smaller anyway, I used some true perhaps unheard of WEGSOG methods to produce my own... I chucked them up in a cordless drill, and spun them against a sanding wheel, to turn them down.... here are the results! the pins are tight. Notice although the holes look offset/offcenter from the casting area for the holes, I did follow the factory pilot holes and it did go straight through to about the same place on the other side, again done with the craftsman 18 volt 1/2 cordless in an apartment.... barefoot the whole time....



It is flush to the end of the bore... even though it doesn't look like it, just not flush to the edge... and the aluminum bar I used was hardened so some marks from beating it on transferred, oh well, no biggie.


AND OF COURSE..... The whole rifle, I have Concrete...check.... Magazine.... check.... Bare feet showing toes..... check.... Unrelated "tactical" knife..... check... Was I missing anything?? I think I covered cammo in the other pics... maybe I need ammo cans, other AK's or a ton of mags. ammo?? ;) Anyone have a handgaurd set that will match that bulgarian hardwood blonde stock?

Hey nice job and be sure to post pics once you have the compensator on it........

October 22, 2007, 09:28
Hopefully that comes in today...if it does.... I will... If it wasn't raining here I would have a ton of empties for it to have scattered about for the photo. At a minimum i might have to drag out the crate, and some mags...

October 22, 2007, 22:11
FINALLY!! It arrived today. I did not have time to get l the stuff together, but I got it on and here it is.... NOW it looks like it is supposed to.



The detail on these AK USA brakes are outstanding. it was internally chromed, even the threads, so it should wear quite well.


October 22, 2007, 22:23
Special thanks to Mosin Guy... I never would have found the 22mm brake, never. Worth every penny, they didn't even charge shipping.

Hey panzer, I told you you would like it and it looks good you did a great job on the sight block install and glad I could help you out,Now go enjoy it buy doing some shooting with it........

October 23, 2007, 21:49
Good Job ... :beer:

October 25, 2007, 04:01
You know, after looking around alot, I think that might be a 5.45 Krinkov fsb.
Then again it could just be a w.a.g........

October 27, 2007, 10:04
Now you need the romy side folder and a forward grip front handguard.

October 29, 2007, 20:36
The Krinkov FSB is also the gas block... It is on my Bulgarian one.

I am not sure I like the donkey dong lower HG.....

Either way, shot about 200 rds through it today, the brake makes a difference. Its just as loud with it or without it, except to bystanders. Its definately louder. The front sight block was not canted and was only a few inces left at 100 yds, elevation was set, so I need to remember to bring the thing to the range to adjust it L/R. If you have never shot a 5.45, you need to! its recoil is less than an AR, and no "sproing" sound. It actually only recoiled a few inches backward when I held it extremely lightly to let it travel. My .45 FAL kicks and jumps more than this thing. I am very happy. Next mod it to fix the inside of the reciever so it holds mags better, fill in the huge voids where the single stack mag supports were. The only firing issues were all related to this loose mag situation, if yuou held on to the mag, it ran great. Russian ammo is dirty and stinky nasty stuff.... No accuracy test, I wouldn't even try it. I mean why bother? it hit man sized all day and thats all it was ever intended to do. I need to get new furniture though, soon. Ironwood designs is making an AK74 specific lower soon, so a whole new stock set will be going on it when those come out.... the front HG's are nasty, no other word for it.

damn, my feet look like yours. Not often you see the big toe being the longest.

Anyway, nice job. I just might have to do it on my SAR3.

October 30, 2007, 21:29
Helps me climb ;) yeah you don't see many like that.... I only see two.
