Are there any Rapid 7 enthusiasts out there who could give me some answers to the following queries. I have a Rapid 7, 22, well it is now !,(serial number 008838) the previous owner having converted it from a 20 calibre, which has never bothered me, and for 10 years gave me good unbroken service, then just before Covid hit, the rifle seemed to start losing air, no trouble I thought just strip it down and replace all seals. This I did , also I replaced the Metal valve with a Acetal valve and matching new exhaust valve of T.R Robb, doing away with fitting the white nylon seal, which goes with servicing the Metal valve. The result of all this ?, still it lost air, and in disgust I have put it away ever since, until now , there is no point having something that does not work !, so I will try again, but a few questions !. 1, Is it possible to narrow down , where the leak is ?, It,s not the bottle as this holds air without any problems when not screwed onto the rifle, also I have read that if you cycle the pellet probe forward with the bottle screwed on, fitting a tight fitting bag over the muzzle will show if air is leaking that way, this also draws a blank. 2, I have many seals I purchased with the rifle, are these still valid to use ?, or would it be better to use new ones and if so, of whom do you recommend ?,as we know Theoben Ltd is not sadly a option ! 3 , Although the Acetal valve and exhaust valve have done no work, should I use new ones again as the rifle is stripped down ?, and again who would you recommend ?. 4 ,Now you can get quick fill adapters that make unscrewing the bottle to fill with air a thing of the past, this quite appeals to me as getting contamination is always a risk when unscrewing the bottle, plus it does not need you to dry fire the rifle to lesson the air pressure when unscrewing, If anyone has had this modification your opinion ?, did you have any problems if it,s on a older bottle ?, mines stamped 1987 !. Any help would be appreciated, All the best !, Elwyn
