  • i just bought one of these to put on a polymer lower I milled from 80% a while back (I used it for testing and while it functions perfectly, I don't trust polymer to hold up with recoil) Looking at the reviews and videos it looks very promising. One competition shooter claims a bit over 1" groups at 450 yards. It uses a delayed blowback similar to HKs design with roller bearings riding on a trundle which keeps the bolt locked until the bullet leaves the barrel giving it bolt gun like accuracy. Should be a fun shooter

    If you get those kinds of results Ill have to have one. .17 HMR is one of my favorite calibers by my Savage cant do that at half the range on a sled.
     
    Range report? Curious if it lives up to your expectation

    Been busier than 1 armed wallpaper hanger. Haven't had time for the range and on the few days I could have made it mother nature has blessed us with more liquid sunshine. .I "might" get to go after the 17th. I will definitely post a report when I shoot her..I have that one and a few others I need to shoot as well as chrono some handloads..I'm going to make a day out of it at DELMARVA then head to Harborside for a crab imperial topped new York strip and a couple orange crushes..
