Zustava m92 PAP : How to replace Handguard?

[ShooterGuy]

So I ordered the appropriate handguard rail from MidWest for my m92, except after looking at it I'm not sure how to get the original handguard off? :banghead:


I've done this for multiple other AK variants but this one seems a bit different. Does anyone know how I can get the original wood hand guards off this thing without damage?

So in this stock image, 1. looks like a retention pin to slide out the top but I havent been able to get it to budge. 2. Is a little lever looking thing sticking out the front, but I haven't figured out its purpose? 3. Is where I cut the spot weld to remove the shroud, but it pertains to a different question about whether I could just touch up with engine paint to cover the cut marks?



Any insight appreciated, thanks!

Would also like to know for my new M85.

Anybody hopefully have some insight to share?

push the upper retention pin to the rear of the gun from the front (rear cover must be up) and the upper hand guard should come off if the piston is out then flip the little lever thing fully to the rear of the gun (this will be nearly impossible to start) then force the lower hand guard to the front (also nearly impossible) and that should be that..

edit:yes three is where you need to cut to remove the thread protector (also nearly impossible to remove took me and a buddy with a pair of vice grips)

good luck and don't be afraid of a little force (within reason, obviously)

Hmm, I couldn't get that retention pin to budge, guess I'll just have to go cowboy on it a little. Guess I'll climb the mountain of the lower guard when I get to it. I already cut the shroud weld with a dremel, took about 15 minutes to cut and polish down the knubs but wasn't too difficult.

I presume you're having difficulty with the lower handguard. The little lever on the bottom that needs to be rotated 180 degrees is VERY tight. I carefully pried mine with a screwdriver to get it started and then tapped it with a punch to get it fully rotated. You need to use a lot of tape to prevent scratches. With the lever rotated I then had to tap the handguard forward with another punch. It too is very tight. With the thread protector on the muzzle removed, the handguard should come off without interference.

After I took mine off I could not completely re-seat the lower handguard against the receiver when I tried to reassemble; it's that tight. I'm going to file it just a bit to make it fit better. There's no reason it should be this tight.

I'm trying to find the Midwest Industries quad rail in stock somewhere. I haven't checked the supply in a few weeks, so I'll have to try again. I have all the other pieces for my SBR project. The MI part seems the most difficult to obtain right now.

How did you get the wood off of the gas tube without damaging it? I'd like to keep it intact if I can but looking at it I'm a bit dumbfounded on how to do that so any experience insight would be excellent!

Put a nylon punch, or other similar object, against it and give a few good whacks. It will move, if you're talking about what i think you're talking about.

Nah I've got dis-assembly down, and once I got it all off once it comes apart pretty easily now that things are lubed up and moving. It was a pain getting it all off the first time though as they were pretty stuck.

What I'm referring to now, is the wood upper piece that goes over the gas tube held in place by the shrouds on either end. I'll need to get that piece off of there to place the quad rail. I see how to get the wood off the lower piece, but that upper piece of wood seems to be fit perfectly snug in there.

Put the squared end in a vice or put a wrench on it to prevent the metal tube from turning. Then, grab the wood and rotate it. Spin it 180 degrees around the tube and slide it out of the slots.

See that's what I expected to do, except the tube has these retention tabs stopping you from just twisting off, I'm curious if there isn't away around these tabs without damaging the wood or cutting the tabs? Unless the tabs are actually attached to the wood and will turn with it? Am a bit hesitant to figure it out first before I go wrenching something lol

Those tabs don't prevent it from being able to be rotated. It just takes a good bit of force.
