I have a Wildcat Predator mod on my 308 and want to use it on my new 300 Blackout so a replacement bridge section and a set of compact rear tubes would do the job, if I could strip the thing!.
I can easily remove the front section, baffles & blast shield etc. but the rear cover (with the Delrin bushing in) and existing bridge section are solid, even putting a wrench on the rear nut won't budge it! (took the paint off though!), tried soaking it in hot water as they suggest but can't get either off. Both were given a coat of copperslip grease when they were fitted and have been removed a while ago.
