Expanding on that a little further, mount a small lightweight videocam with an audio pickup to the eyepiece of that scope (the scope being mounted in such a way that it doesn't block the *real* sights but adjusted to the same POA), and dryfire away to your heart's content. Playing that video back in...

LGR seals

Four seals if you include the piston seal - if it's not holding air, the issue is either valve seal or piston seal. Open the breech, place a finger over the hole that leads back into the cylinder area and cycle the piston; if you feel air forcing out past your finger as you swing the lever forward i...

Thanks everybody! I just wound up machining (and properly hardening) a special bit to use with an impact screwdriver to remove the old screws - one slot is left a little chewed up, but I'll just make a replacement set to take a hex key so I don't have this issue next time. I was hoping to avoid the ...

Walther LGR "coin slot" screws?

Finally got around to ordering a replacement piston seal, but... Those 2 flat head screws with the radius-bottom slot that hold the piston lever assembly in the rear of the receiver - is there a special driver available somewhere for those things? Also, are replacement screws available for those of ...
