PSL-54C help

[LouisCipher777]

does anyone know where I can find info on removing the barrel of a PSL-54C?

or, if anyone knows the weapon well can you answer these questions...

A) how do i get this off the weapon? (or can I at all without taking the front sight and gas port off)

B) I assume this pin holds this piece on, but once I take the pin out, how do I get it off the barrel?

C) Are these rivets or are they pins? Do I have to grind or cut them off to get the barrel off of the receiver?

The 3 on the receiver are rivets. Not meaning to seem snarky, but I don't recommend attacking this one if you need our help to identify pins vs. rivets.

Why do you want to remove the barrel, anyway?

 

[LouisCipher777]

I figured they were rivets, but at the same time they are flat and look like they can be knocked out from the other side.

I want to have the barrel cryo treated, but right now I'm trying to decide if I can even take the barrel off and put it back on without ruining the weapon.

To be totally honest with you, cryo treating a PSL is most likely not going to be worth the time, trouble, and cost. I have no reason to believe that the rifle itself is mechanically capable of accuracy sufficient to justify a cryo treatment.

If you want an accurate 7.62x54r, check out the Finnish competition Mosins (I don't recall the designation).

Exactly.

The accuracy benefits of cryogenic treatment are fairly minimal to begin with (assuming the process doesn't adversely affect accuracy, which I've heard of). The PSL is a minute of torso to 600 yards rifle, as it was designed to be. If you wanna win competitions with an autoloader, better move to the AR-10 platform.

One option to look at is a company called Rifle Dynamics. They are here in Vegas and have done some impressive work on the PSL. I have seen the guns firsthand at some of the local shoots. The package is also priced very reasonably.

the point of having it cryo treated isn't so much to increase the overall accuracy, but I have been told by several people that it will stop the barrel warping when it gets hot.

as it stands right now, during rapid fire cadence exercises, it walks up and to the right, and a couple people have told me that cryo treating the barrel will fix that problem.

It may provide a marginal improvement in that regard, but the barrel of the PSL is quite long and pencil thin. Ever seen one fire in slow motion? They whip something awful.

Between that and all the pressure exerted on it at multiple points, I just don't think you'd realize any benefit. But it's your rifle

If your dead set on Cryoing it - Just take the stock off the rear and Cryo the entire barrel and reciever as one peice. You can take the brake off the front to make it a little shorter.

If you take the rivets (C) out that hold the barrel trunion to the reciever you will have to get a new rivet kit and then brad the new rivets in place after you get the barrel assy back from Cryo. Then you will have to re-headspace the bolt. It's not that big of a deal as people do this all the time with AK kit rifles, but you can screw it up.

That is a lot of work and possible screw up for the VERY marginal improvement Cryo offers on even the best rifle platforms. Considering the PSL platform's inherent problems (already noted by MachIVshooter) and accuracy potential, I don't think it worth it.

upon further inspection, and driver's advice, I'm going to have the receiver treated too. I use this rifle all the time, and it is my go-to MBR, and cryo treating at a shop here in town is only $60, so if I can see any improvement at all it's worth the money.

The problem of barrel whip on a PSL is reduced significantly by using the bayonet. It works as a buffer, and improves the barrel harmonics enough to shoot quarter sized stickers at 100y.

And I can't figure out any valid way to take off parts A or B, so I guess I'll just take off the stock and pull the trigger group and treat it all.

Thanks for the advice y'all.

Psl problems

I had gone shooting the other day with a buddy, and i had notice that everytime i fire a round, it would reload but wouldn't fire again until i cocked it halfway back. or i would have to squeeze the trigger a few times until I heard a click. is this trigger slap? I would appreciate some pointers. Thanks.

I wish I had a psl. That is if they are as accurate as wiki claims. 1300 meters scoped.
