Romanian PSL SUPPRESSED!

Published on January 13, 2016
Duration: 13:19

This video details a DIY modification to safely suppress a Romanian PSL rifle, addressing the common issue of over-gassing. By drilling and tapping the gas block to install a vented set screw, gas flow is regulated, preventing damage to the rifle's rear trunnion. While the modification allows for significantly reduced recoil and a more pleasant shooting experience with the 7.62x54R caliber, careful tuning is required, and it may impact the rifle's long-term durability.

Quick Summary

Safely suppressing a Romanian PSL involves a DIY gas block modification. Drill the gas port to 5/32" and tap for a 10-32 vented set screw to regulate gas flow, preventing rear trunnion damage. This allows for reduced recoil, but requires careful tuning and avoids corrosive ammo.

Frequently Asked Questions

How can a Romanian PSL be safely suppressed?

Safely suppressing a Romanian PSL requires modifying the gas block. This typically involves drilling the gas port to a smaller size (e.g., 5/32") and tapping it to install a 10-32 vented set screw. This screw regulates gas flow, preventing over-gassing and potential damage to the rifle's rear trunnion.

What are the risks of suppressing a stock Romanian PSL?

Suppressing a stock Romanian PSL without modification is dangerous due to over-gassing. This excessive gas pressure can damage the rifle's rear trunnion, especially when firing heavy ammunition or using a suppressor, potentially leading to catastrophic failure.

What suppressor is used on the modified PSL in the video?

The video features a Griffin Armament Recce 7 .30 caliber suppressor. It is attached to the PSL using a Griffin muzzle device specifically designed for the rifle's 14x1 left-hand thread pitch.

Why should corrosive ammo be avoided with suppressed PSLs?

Corrosive ammunition leaves residue that can damage firearm components over time. When shooting suppressed, this residue can be trapped within the suppressor and the rifle's gas system, potentially causing accelerated corrosion and damage to both the suppressor and the firearm itself.
