Steyr should offer a “HP” conversion kit to those who already have a LP10/evo10. They would sell like hot cakes.


Wonder what would be involved? Steyr's exploded view with parts list for the LP50 is for the "standard" model so no way to check differences. Assume a regulator and hammer spring change would be necessary. Hopefully they will ad the RF and HP drawings.

Anyone ever messed with the velocity adjustments to check possibilities?


I also assume a modified regulator and hammer spring. I think the standard model with the velocity screw cranked up, will only deliver around 550-600 fps with light weight pellets.



My testing confirms your thoughts Kevin.

Did some velocity testing with my "Standard" LP50 Compact by turning the adjusting screw CW 1/2 turn at a time using RWS Basic 7.0g pellets. Made the adjustment and fired 5 shots, no test shots to settle the reg.
Baseline from the factory at test time was 485fps (5 joules).
1/2 turn yielded 495 fps
1 turn was 515.6 fps
1-1/2 turn was 523 fps
2 turns was 529 fps
2-1/2 turns netted 544 fps
3 turns was 551 fps (6.4 joules)
Stopped at 3 turns even though it felt there was more left. Backed it off to 1 turn cause I liked the "feel" of the shot and left it there for now. More testing showed very consistent speed and accuracy at this setting, as it was at the factory setting. Shot count went from approx 90 at factory settings to approx 70 now.

For comparison:
Factory settings for the new RF model (both full size and compact) is 551 fps (7.48 joule)
The HP full size model will come shooting at 722 fps (12.35 joule) and the compact at 673 fps (10.74 joule).
Factory settings made with 7.87 grain pellets for the HP and 8.18 grain for the RF.

So what is the difference between a standard LP50 and a RF model?

That's a good question. The obvious answer is that the RF comes set up to shoot at 7.5 joules whereas the standard is set at 5. I have no idea if the internals are the same. Hopefully Steyr will put out an exploded view with parts list of the new models so we can take a look.

Do the folks at Pilk's have any input on the new models??
