PSL54 Sub MOA Rifle in hands of teenager… Accurizing it in 3 easy steps!

20/05/07 at 7.10am   /   by Rob Ski   /   20 Comments

My PSL54 (2018 model – recent import) is sub MOA rifle. I even brought teenager to prove it!
As you may remember, my PSL54 was shooting around 1.65 MOA at the beginning (first video on it). So what could be done to squeeze out any last drop of accuracy from it? Actually it is very simple and all upgrades are user level operations!

  1. Rob,
    great shooting by your daughter. I’m working on following your lead accurizing my 2019 PSL and have picked up the KNS piston from the AKOU store. Which trigger group did you get from the Fime group for your PSL? I know you said you did some polishing on it but did it require any modification to fit your gun?
    Also can you recommend a scope to me for my PSL. I’ve got the exact same scope you have on your PSL but with my crappy vision I have to wear reading glasses for the reticle to not be blurry. I need something with a diopter adjustment.

    Thank you for all you do for our shooting sport.

  3. Hey Rob, in looking in doing the same thing myself I was wondering if you had considered the RSA adjustable PSL trigger & if so what made you decide on the FIME group trigger instead?

  4. Robski, I bought a KNS piston for my PSL and couldn’t be happier. Sorry I did not get from you, I didn’t see it on your page till after I ordered. I just ordered the Fime FCG 7.62x54r trigger – 6lbs. pull. I take it that is the on you got. Anyway with just the piston and Tapco trigger I am now hitting at .50 -.75 moa with the S&B 174 gr OTM at 100 yards. I am not using a suppressor and I am using one setting for both machine gun ammo and OTMs. Inspected my rifle closely after use and not a hint of anything bad happening back in the trunion area. Thanks again !!

  6. Rob,
    Following your lead here, bought a PSL, piston, and trigger. I am wondering how much of a difference you saw when you replaced the original muzzle brake. I am thinking of doing it as well but it is a little more involved than the other two. Did you measure the effects it had on your groups? Also, does the suppressor have an effect on group size, or just the threaded, high quality brake?
    Thank you!

    • Daniel, i would keep for now your original muzzle brake and just see how it does with better ammo when you have KNS piston and trigger installed. Just from this you should see some difference – work out ammo it likes first. Mine really prefers that 174gr SB ammo man.

  7. I had read much on the PSL before I purchased one myself, I knew it was over gassed so I immediately purchased the KNS piston. (I would like an adjustable gas block like definitive arms DAG-13 but I do not think it fits PSL) I was hesitant to replace the FCG so I polished and installed Carolina Shooters Supply mainspring, which for around $7, lightens the trigger pull significantly. I may try FIMEgroup’s 54r trigger after watching this video.

    Now, I am wondering if there is any more possible upgrades? Have you done anything to your rifle since? Is there anything we can do to address the poor barrel harmonics or heat dissipation?

    Thank you

    • Michael, no, I’m just shooting it like it is because it works so great, I’m not “touching it”. I’m happy with were it stands.
      @haet – you just have to watch your rate of fire, which today’s ammo prices, shouldn’t be a problem…lol

  8. Do you have any problems with case denting on fired rounds with the KNS piston? About 3 out of 4 rounds have a dent halfway down the case, and this is with military surplus, Tula and S&B ball ammo.

    • PSL will dent cases with or without piston. If you want to prevent this from happening, you can add piece of the thick tape at the edge of the dust cover where case is hitting it upon ejection.

  9. You said you had friends at Cuigr. Can you ask them about the PSL in 7.62NATO? I have one, and can’t find any information on it.
