Default SAR 3 questions

So I got my first AK! Its a Romy SAR3 in 5.56 and its on its way to my FFL, but due to lack of youtube videos I am without a few answers to some questions.

1. The barrel does not seem to be threaded, is it possible to thread it and mount an AK74 muzzle break on it?

2. From what i have heard the bolt is proprietary, is there any way to modify extractors or even replace the bolt to something more durable?

3. I paid 850 shipped for the thing, did I get bent over?

Thanks guys!

As an easier path, you'd want to install an AK74 front sight block (these are threaded for the AK74 muzzle brake)

Look for a Romanian threaded FSB. They are 22mm, not 24mm like the Russian and Bulgarian FSBs.

Yes, and 22mm muzzle devices are made of unobtanium, hence my suggestion.

The SAR3 was an interesting platform for sure. Not the most reliable of the SAR series. Back when new the most popular mod was a Red Star Arms hammer. They are very mag picky usually the German Wieger mags and Romanian copy were the best bet for reliability. There used to be Robinson Arm. followers for East German bakelite 5.45 mags that worked but those seem to disappear 10 years ago. As far as price you have already purchased it so that is over with time to move on. I paid $300 for mine used in 2004 so it is hard for me to see $800 Romanian guns period. Just like guys from the 80's hate seeing $2k pre-ban Chinese guns. I had issues with brass 5.56 in a lot of my past 5.56 AK's. The only one I did not was my SA M5's but Arsenal's....

Bulgy AK74 bolts and carriers can be modified to fit.

Left locking lug of the AK74 bolt will need to be shortened about 1/4 inch on the front.

The ejector relief on the bolt will need to be lengthened about 1/2 inch toward the rear.

Test fire and see if the rounds are ejected. If they are not ejected then the extractor may need to be modified by a little filing on part that connects the extractor blade to the body of the bolt. This will allow the extractor to sit deeper in the bolt face to better grip the .223 case rim.

The bottom of the carrier may need to be polished to fit properly.

I think the barrel OD is too small for a bulgarian FSB.

It is easy enough to shim it out.

I have a couple of them. Someone made a run of them a few years back. I forget which manufacturer. They are not for sale, however.

Another option is to simply thread the barrel and use a thread adapter allowing the use of 22 or 24mm muzzle devices, granted not authentic but visually serves its purpose

Well, so long as you thread it x28 (ain't a lot of barrel there)


(not too many x28 to 24mm adapters out there, either)

So from the looks of things theres about an inch of unthreaded barrel. If i go the whole Bulgy FSB and shim the barrel route, what would be the best way of removing that extra inch?

Also, the next step after getting the 74 muzzle break is, thats right you guessed it, a side folding stock. Is there a thread that explains how to do that? To my knowledge the process is a bit complicated and high risk.

You dont cut the barrel, the FSB sits flush with the end of the barrel

A side folding Romanian or Polish wire stock should fit without modifications. A properly installed triangle folder is requires rear trunnion and receiver work. Once you change the stock, do you plan to sell the wood stock? If so, I'm interested. I need a whole SAR furniture set for a SAR 3 project I'm working on.

Remove rear stock screw

Remove stock

Insert new stock

Install rear stock screw

Slight thread highjack but how would you guys value a gently used Sar-3 with original hardwood furniture, still in unthreaded config? Is $700 fair in today’s market?

"Slight"?

Not a "total change of topic"?

Threading the barrel is a three part issue.
The diameter should either be .500" +/- to thread 1/28 RH or .550" +/- to thread,14mmx1 LH.

The second issue is the current FSB is a neutered former 22mm integral thread part.

Third., the 22mm threaded part was cut away.
This left a longer than normal setback on the remainder of the FSB.
Because of this., some mu,zle devices will not fit as that space is too long.

Also a standard plunger will not work in that FSB.

Buy a few Weiger mags and shoot it.
Leave as is unless you want to dump more $$ into mods

no, but Jmac made a adapter as stated above, also and you will like get PMs Trying to sell you Aftermarket 74 style brakes with usable thread pitches.

2. From what i have heard the bolt is proprietary, is there any way to modify extractors or even replace the bolt to something more durable?

As long as your hammer hits the firing pin square you wont ever wear a bolt out. I bought a red star arms trigger and it is my best AK trigger. The century standard AKM hammer in mine was half ass reprofiled by them (922 part) to match up to the short tailed bolt. Wasnt perfect... buy a Redstar.

3. I paid 850 shipped for the thing, did I get bent over?

I have more than that in mine but I have the the FSB/MB conversion MDL97 clone. These were imported with modified 5.45 mags so they got a bad initial reputation. Correct Weiger or Romanian mags will have it running perfect like mine.

Thanks so much guys! I really appreciate the information.
I do however have two last questions.

Can I swap the gas block to one with a bayonet lug?

Also I heard FB Radom Mags work well in this rifle with some slight modification. Is that true?

alright, I lied. I have a few more questions.

is the barrel diameter thinner than 5.45 barrels? I have a bulgy 74 flash hider and all id need is a bulgy FSP, but i dont want to spend more money if it wont work.

I revisited the SAR 3 that I bought years ago & you guys bring up some issues I had forgotten about.
#1 is the FCG which is a double hook G3 Tapco, unmodified. The hammer hits the bolt @ a weird angle that will deform the tailstock if fired enough. Memory fails me if I changed it out years ago, but it looks unused & is something I would do(the double hook, I used everywhere years ago). It needs changing & free up the FCG for another build.

#2 is (Nails says not an issue ever) the gas piston has been welded into the carrier & not pinned as Ak's are originally designed. If my poor memory serves me right, this weld will break @ some time cause more problems down the line. This needs a bit of correcting before range time.

#3 is the no muzzle brake issue, even though I bought a Bulgy FSB & a '74 brake that has been gone over here that it won't fit without a shimming job.

#4 is a fixed problem of the rear stock being converted to an original Romy sidefolder which works great, better than the fake folder that came with it from the original owner.

These reminder fixes need to be done before I take it to range time to eliminate problems down the line. Since I have less that $300.00 in the rifle, it shouldn't break the bank.

This is nothingburger.

There are hundreds of thousands of WASRs (all types) with welded gas pistons and you only really hear about "could break" and "not what Santa Kalashnikov intended".

Alright Nails, I will scrub that one issue from my list about the SAR 3 faults that need to be fixed. The FCG is still first on the list as it has to be done now before damage happens to the bolt tail. The brake issue is just a personal peave that I want to get taken care of. Thanks for noticing my old guy bad information & saving me some work that does not need doing.

Okay, since it is raining for the last two days, I located the original FCG that the factory put in the rifle & replaced the Tapco G3 FCG that I put in there years ago. Now the hammer face touches the face of the bolt tail flush instead of on the top only. Another problem fixed and only one more to go, but that one is not gong to be as easy as the last two. Another upside is I have a G3 FCG to put into another build when the time comes. Didn't really want to spend $100.00 plus shipping on a RSF FCG just for this rifle.
