BSA Mercury

[SRV1]

could someone in the know with mercury's answer this for me not trying to hijack the thread im in the process of servicing my mk2 mercury should the section that's fitted to the under side of the cylinder has a single screw with split washer part no BK003 in the mercury diagram. my question is should this part be a tight fit to the cylinder or a loose fit as the one on my rifle is loose like others have said in this thread i doubt mine rifle has ever been serviced.its a mk11 in 177. thanks in advance.

Hi, with the stock and action separated, tighten the screw such that the bracket can be moved with a a little pressure. Put action in stock with just the long rear screw nipped up, have a look through the stock screw holes to check alignment. If not, use a pin punch or similar to move the bracket into alignment through the stock hole. Remove action, fully tighten bracket screw and reassemble. If the screw is not tight, through recoil, it will probably drop out, or if loose, the accuracy will suffer as the action will be jumping round with each shot.

All the best

Gents.
I've finally got to the point of assembly and spring replacement. I've got a couple of Titan 2 springs...which I believe are the ones to use...although longer than the originals....I'm not surprised due to the use they have had...do you believe these need cutting and then trial and error by checking over my Skan...or do Mercury's never make 12 fpe due to their design?🤣
Many thanks in advance. 👍

Hi,i have had a fair few,they make just a tad more than the airsporter.i think that it will get to 11 ish but wont be very happy,10 is sweet and does the job
I have the t robb head in mine(keeper) and it is a real cracker to shoot,a far better and simpler gun than the hw35.
