Beware on that RTI. I bought one before they raised the price to current, just so I could get an example of a long lee. If you haven't received it yet, you are in for a greasy mess. Mine was mostly complete. BSA speed. No provision for clearing rod. My bolt has the notches for the dust cover, but it was not included. You should make sure yours is safe. Mine was not in Good/Very good condition, close to poor/parts. Bore is bad, no blue. Mine is downright unsafe. It was used for drills so much that the locking lugs on the bolt and receiver is ground uneven. I can send a picture if you want.
IMO not worth getting the dust cover for.
