cocker--mkII, gas thru, full force bolt, rat 3:12
bm2k, mega reg, gas thru, eclipse venturi
Honestly, I haven't figure it out yet
light weight, good looks, reasonable price, extremely efficient--shot count will go way up.
Not accurate, loud, appears to be too tight and must have internal flaws
I think I must have gotten a bad one. It'll shoot very accurately at 210 fps, but turn it up to 275 or higher and it shoots like the barrel is wet. Both my cocker and my bm are very lo pressure, or I'm sure it would break balls like crazy. I have run nothing but fresh All star and Marbs through it, and neither seem to fit. In the last year I've played with it maybe a half dozen times, and every time I end up pulling it off, throwing my carbon fiber on, having a better time and swearing the Lapco is going to storage. This is it. I've had it with the thing. I give it a 5 because the price was right and it is very efficient. I get 1200 plus with my cocker and a 68 3K tank. But if you want to shoot faster than 210 fps, forget about it. I can't recommend it. All the barrels listed above are more accurate.
