Bought a 1956 .177 from a gent on here a few years back. Lovely little gun. Had a couple initial issues with the breech lock up going solid & the sights (think the latter had a bump at some stage).

Anyway. took it out of the cupboard today for the first plink for a few years. Noticed the end cap (ECP019 End cap. Diana) seems to spin freely/not grip onto the thread.

Haven't taken it out of the stock yet to check - but wondered if I just used some PTFE plumbers tape/thread sealant it would stop the spinning/keep crap out.

Any Thorts?
