The Zastava PAP M77 PS has classic AK styling and is chambered .308 caliber! The M77 features an adjustable gas system for flawless functioning with many types of ammunition, acold-forged barrel technology that offers excellent accuracy and performance. Key internal components are all machined from solid steel.
I am heavily researching this rifle with the intent to purchase. So far I have found few issues that will keep me from purchasing it. I am workign through ways to mitigate those lingering issues.
This thread is a place to discuss, ask questions, and share about the Zastava M77.
Issue number 1. Additional magazines. Since the rifle only comes with 2 10 rounders I need a source for reliable, and hopefully affordable, magazines for the weapon system. Thank you to gunluvver over at The AK Forum for providing a solution. This is another huge selling point for the Zastava PAP M77 over the Vepr or Saiga is the capability to use modified M14 mags without having to modify the rifle. I would much rather mess up a $15-$25 magazine then a $600 rifle.
A notch needs to be cut in the front face of the mag to act as a mag catch. M-14’s use a hole in the front of the mag to lock, the notch has to be through the lower half.
The mag has two layers of metal here. Grind or file just through the first layer. On the first mags I did, I used a rotary file in my die grinder to cut the groove, and I cut through both layers. I found you don’t have to go that deep, and the notch area will be stronger.
Here’s the M14 mag installed.
Complete summary of modification is here.
Issue number 2 (UNSOLVED). Muzzle brake / Flash Suppressor. I don’t like the slant one that is on there. I am cheap, I want something different.
From research I know the below:
1) there is a tack weld holding on the stock muzzle device.
2) The barrel is threaded 14mmx1left hand.
3) There is no detent pin and spring on the end of the barrel but it is drilled for one.
Now I need to find an affordable muzzle device that I like.
I am not sure I am going to buy this piece but it is cool to adapt the slant cut receiver on the Zastava PA M77 to the traditional AK style.
Here is another accessory I can use if I decide to use optics.

Not sure if I want this but if you use the slant cut stock adapter below you can use standard M70 furniture like the below.
I will use this post as a running cost of the build I want fro the Zastava M77 Rifle. I will update it as I find new pieces until I either purchase or decide to take another route for a .308 rifle.
Cost of build:
Zastava PAP M77 .308 Rifle – $564.94
AIMR Flash Hider from cncwarrior.com – $24.99
Barrel Detent Pin – $10
ACE Zastava Slant Cut Receiver Block Adapter – $59.99
INTRAFUSE® M70 Adaptor and Stock Set – $54.99
AK Pistol grip – $20
TOTAL = $680
Found this today. It looks like a newer version of the Zastava M77 PAP. Looks like a shorter barrel and it has the picatiny rail on the top. They are asking $885 though. A bit overpriced.
I found a link to the manual for the Zastava M77. Will look over it this evening.
All this research on this rifle and now I am not sure I want to go with a rifle that shoots the 7.62 x 51 round.
This is an awesome setup. This guy did some custom work though.
I bought a Zastava M77 (.308) rifle when J&G had them for $499 a while back. Repaired rear receiver with M70 trunnion from Apex. Converted it for original stock with a little less cant to stock so it would be more inline with the bore, made an adapter, mounted Magpul PRS w/adjustable LOP and cheek piece.
Got a ZRAK mount that centers over bore, removed rings and threaded/mounted a length of picatinny stock to mount, moving scope more forward to cure eye relief problem with scope rail position. Mounted IOR Valdada 4×24 M2 scope w/illuminated reticle /range estimator / BDC with V-TAC quick release rings.. Converted surplus Acog Killflash ARD with laser filter. Installed RPK windage adjustable rear sight.
Ground off muzzle nut, installed muzzle brake w/detent pin assembly. Usual trigger polish etc.. installed Wilson buffer.
Converted some Galil 20 and 15 round magazines.
Kept original upper and lower hand guards on it because they match Magpul PRS and Tapco SAW pistol grip.
Sighted it in Saturday shooting across my pond at objects around the edge since the water is low. At 100 yards I shot 4 holes thru my swinging 6×6 inch steel target that were all touching. Target lases at 103 meters from my porch. It was one jagged hole. I want to get it on paper at 100 and the 300 yard plates. Was shooting some surplus LC XM80CS 149 gr FMJ.
Worked the night shift so it was cool and could work slowly and uninterrupted.
I want to repair the cleaning rod mount and mount my bipod on it. Going to mount a short piece of picatinny on the lower forward part of receiver and mount Atlas BT-LW17 Quick release bipod similar to the Dragunov, SVD etc…….
Was so impressed with it Saturday I ordered another one. Will see what accessories become available.
Good video on conversion of the M77 from stock setup to more traditional AK setup.
Here is a video on the optic I would get if / when I get this rifle.

Read a previous post regarding the Zastava M77 .308. I have one on order. Two basic questions to those in the know: do they all come with a welded on barrel nut? If so, how does one remove the nut (to install a muzzle device) without damaging the threads? Locate a gunsmith to machine it off? Is there a trick to breaking the weld without destroying the threads?
There have been few reports I have read that some come with the barrel nut not welded on. I have seen nothing to substantiate these claims and I doubt I will. That means most likely the barrel nut will be welded on. I have the Zastava M92 AK Pistol and the barrel nut on it was welded on. It was easy to remove with a dremmel. The muzzle nut will go past he end of the threads and there will be a gap where the barrel nut and the barrel. It will be easier if you have a vice. I did not have one. I just re-blued the area affect by the cut after I had smoothed it.
Thanks very much to all who welcomed me and particularly for the informative M77 fix. This news is good; I was afraid the weld would be a big issue which could ruin the threads. Thankfully, I now know otherwise. Great info, very much appreciated! I consider you all my friends and although I’ve had a lot of experience (unfortunately) with M-14’s & 16’s in less than friendly situations, the Zastava M77 is a new application for me.
