Didn't post that I got it out for a spin a few weeks back and it ran without a flaw. Put a few hundred down range and ran a few drills with it. With the A5H3 and Green spring with the Mini Surefire, it's smooth as can be.

Range report from last weekend. Got a chance to stretch it out to 300 and 500 on steel plate. Mk262s flew nicely. Even with my ears all the way turned up, you couldn't really hear the plate at 500. It was freshly pinted black with a full dirt berm behind it, so I was able to see hits better through a spotting scope. They have big tire straps holding the 1/2 inch plate and the 77gr round doesn't do much to it. No wind which was very nice. At least I know that it has the legs to be a performer at 500. Very happy with this rig, as I thought I would be.
