Ok - Loctite seems like the obvious way to go, but it will most likely get on the buffer. Also, this rifle gets pretty dirty, so I will need to break it down for cleaning from time to time. Is there any reason not to use loctite? Should I just crank it on very tight? The bolt in question is part #30 in the exploded view. You can view it at this web address.
Look at the SL-7 under rifles.
Thanks for your help.
