Default Zastava M76 build

It has been awhile since I built a Zastava M76 rifle. I still have a couple of these kits to build. This one has an original Serbian barrel.

I riveted the bullet guide and the front of the trigger guard. Headspaced it and checked the feed and lock up.

Need to finish riveting the trigger guard and set the RSB and barrel pin.
The build is pretty simple like a milled AK. The optics rail takes a bit of rigging to set the rivets but not bad.
I plan to spray it with the new Dura Coat matte blue black finish I purchased at Knob Creek last week. We shall see.





UPDATE 4/19

Worked a few more hours on the M76.

Set the barrel pin and RSB pin.

Function checked the action, mag & feed & BHO..
Test fit the furniture.

Finished the trigger guard rivets and the optics rail rivets.

Cut the bevel and fit the front receiver cover plate

Plan to use an ALG trigger and finish in Duracoat two part matte blue/black finish for a first time use of that product.
Probably after test fire and scope zero.

looks good, nice to see the older kits.

Is that an arsenal repair or just the grain of the LHG?

Just the grain. The stocks are still semi-cosmoline covered. I clean it up after I finish putting it together.

What are you doing for a lower cover on that receiver? Does AWO make one?

It is in the picture just below the RSB. I have to form the dovetail in it for fitment to the receiver. It is really just a piece of sheet stock that you form to fit the bullet guide rivet access area.
That one came with the kit from ORF back in early 2010 when I had some dealings with Todd Grove before he passed away.

Can you show your process for installing the rivets on the scope rail?

I'll try to get a few pics of the rivet install for the optics rail.
I use the bolt cutter rivet squishers and swell neck rivets that seat in the v neck opening in the rail. Pre flatten the bead so the protrusion is minimal but adequate on the rail side. I use a small flat bucking plate in the channel to crush the heads flat to the channel in the rail.

Never had any mag well issues. The right side upper area on the front of the receiver at the barrel pin pillar needed radiuses for bolt carrier clearance. A simple file or moto tool fix. It created tilting and binding in the carrier to bolt contact and often bound the bolt in the locking lugs. Once fixed., good to go.

The left side bolt head lug channel in the receiver was cut/milled short on a few and had to be clearance for the left lug to travel freely into the bullet guide turning ramp etc.
Otherwise except for a slightly low magazine lock up that could create bolt ride over on the cartridge the receivers are good to go. Thin or delete the trigger guard plate.

Some of the fixes though not complex were not as easy to find or discover without a good bit of head and butt scratching. I did a lot of that 5 years ago or so.
But the price was right.

Never experienced that issue. I used TAPCO double hook triggers.

I have an ALG FCG unit for this build that I'm going to try for the first time..

Actually that is a good thing. the mag wells on most every one were a tad too wide and ma have contributed to the follower nosedive. Though that problem seems to be primarily a magazine design flaw by Zastava.

Ever seen integrated rails from ORF? I got a couple years back that were made for M76 and they are very nice receivers.

I wish that AWO/ORF/WLA would stop drilling the goddamned barrel pin hole.

Is that bottom receiver marked as ORF?. I have seen a very few ORF receivers with that lightening cut but never really inspected the optics rail attachment.
The Wiselite/Patterson and the more dished pattern like in the second pic.

You joined that other board in 69! Know where to go when I need a story about sugar costing 1/2 a shilling in the old world.

She's a bute.
Any issues pop up & do you use a collar to press or just a penny with these longer ones?

Generally I use brass pipe sections or a shaft collars and pipes for barrel install. This one was a pretty light interference fit so I just pressed it with a brass puck on the barrel. Maybe only .0005" interference. They varied a good bit in the M76"s I have built. Milspec vs Green Mountain as well.
Barrel pin was nice & tight after reaming. I had a expert welder friend lay a very fine weld line at the rear of the pin channel as it was probably 4-5 thousands too deep when headspaced.
This fellow was a team leader in the welding department at a GE jet engine assembly facility. Welds up a lot of reworks like 1919's, MG42, M60's etc. Got the right stuff and the right feel.

I installed the ALG fire control group but not all that impressed.

Sorry for delay,

yes its a ORF, Todd did really good on these and the cuts are spot on. I found one without the integrated rail I bought awhile back as well. Everything is same except no rail on that one.
