The buffer spring has 27 coils and is this make and model found on Midway USA Jp Enterprises tuned & polished buffer spring 308 The receiver extension is 10 in long and was purchased from Luth-ar.com Still working on photos having trouble loading them unfortunately.

The receiver extension is a DPMS Rifle Length Tube- will measure this evening I took a few images of the extension mounted to the lower and there were some scrape marks on the bottom side of the tube. Would reference picture but unable to post currently. No scrapes or marks on Under side of BCG. Will post measurements tomorrow. Thank you for all your ideas and help so far.

Currently making my way through my first 308 build and have run into an issue of the BCG becoming stuck when charging the rifle. The build is not complete yet as I am still lacking handguard, barrel, and optic but do not want to proceed if I have an incompatible parts combo currently. The BCG will move freely if the rear take down pin is inserted halfway or fully removed, but will not let the BCG charge and return to home without some coxing.
