BSA Ultra MMC Strip XTX

This video shows how to strip the older BSA Ultra MMC to get it ready for fitting a regulator. Assembling it is a reverse of the the strip down. Once the action is back together you can fill it with air, make sure it is airtight and then check and set the power via the hammer spring pre-load adjuster. There are other videos on my channel that show how to adjust the power.
If in doubt please seek the advice of a professional if you are at all unsure or not competent, I will not be held responsible if you damage your rifle or yourself by trying to copy what I have shown in this video.
