Hi Springrrrr, Thanks for the reply. I just finished making my guide tonight. I'll post a pic and dimensions in case it's of use to anyone. Have to install it tomorrow and check I can still cock the gun since I made it as long as possible.
Hi Héctor,I had time to test my new guide briefly. It was my first attempt at making one. I think I may have made it a bit too tight. More line 0.02" than 0.002" It was quite tight to get the spring on for assembly. I was thinking I can always make it smaller, but I'm not sure if I will be able to get the guide back out from the spring in one piece.This is the change different in fps before and after.RWS Super Field 15.9 grFactory guide = 825 fps (24.0 fpe)Custom guide = 770 fps (20.9 fpe)Is there any problem using it like this (other than the loss of power)? I wondered if the spring might be putting too much pulling force on the guide and break it.The up side is the twang is gone, it must be quieter now as I can here the pellet flying through the air now , where as before that was mostly masked by the twang.I haven't had time to test for fps spread and accuracy yet.CheersBruce
