help on walther lp 300

Post by 97nick »

Hi guys I just bought today a second hand Walther LP300, that looks new :)
really pleased with it and its shooting great.
one thing though is when I unscrewed the cylinder, filled it, then screwed it back on, I noted the barrel was not straight! on looking at it I saw a thin foam pad under the muzzle break touching the cylinder. when the cylinder was screwed back in, the friction was pushing the barrel over, and the pad pushed over to the left as well. is this a common problem? when I unscrewed the cylinder it pushed the barrel to the opposite side till the cylinder was lose enough to come away from the pad.

what should I do?! I don't fancy pushing the barrel over each time I change the tank, then having to re-zero :(

please help! (by the way, this means my Tau 7 match is now up for sale...)

Just bend it once. You can gawp at this, but the factories all have barrel benders (straighteners) on staff. It will not affect accuracy at all.

I have straightened a air rifle barrel just by smacking it once on a carpeted cement floor.

Yeah, I know...kludge craftsmanship.

Just remove the foam patch...

It was probably put there by the previous owner so that the cylinder didn't touch the barrel when he screwed it in.

There should be a very small gap between the barrel and the cylinder.

Hope this helps

The foam pad is factory fitted, Part 111.
If the barrel is moving then the barrel locating screws are loose, the barrel should be firm in the frame. The foam should only just touch the tank and act as a damper only.

Sorry... I was replying from memory... At it isn't what it used to be!

David's answer is right on the money.
