Theoben Rapid 7

Hi all,new to this site and I need some help.
I bought my s/hand theoben rapid on saturday just gone,and it does not seem to be holding a charge.I got it charged about 2 hous ago and when I went to take it out there was no air left whatsoever.O'ring seems o.k.,,,valve on bottle does not seem to be leaking.HELP!!

few places to check,remove silencer and smear a blob of oil over muzzle,see if it bubbles of,if so its your valve body or stem or both,is it mk1 or 2.

blanking plug under the action is a prime suspect on newer blocks.

if it is were mark says it will be the dowty seal,you dont always have to buy a new one,just put it in a pan of boiling water,not the gun just the dowty

Hi KevG,,it's a mark11!!

also check the regulator(if it as one fitted)the small hole in the reg body near were it joins the action,put some spit on there to see if it bubbles

after all that it tunrned out to be the O ring on the bddy bottle ,anyway all sorted now,just need to get out and zero in.any ideas on what range would be best?

This is a thread I put on another forum. You may find it helpful

Checking for leaks is easy and the solution usually a new O ring or tightening up of something. You do NOT need to take the rifle to a gunsmith in the first instance.
1. Take rifle action out of stock and place in gun cradle if you have one or on wooden blocks if you don't.
2. Using a light machine oil (3 in 1) put a drop everywhere air could escape. These are: underneath blanking plug, regulator join to block,small hole on side of regulator body, bottle join to regulator and finally the bottle valve join to bottle itself.
3. If there is a leak in any of these places bubbles will be visible almost immediately.
4. Finally, the balloon test which is very easy. With bolt in forward position but with rifle unloaded and uncocked, fit a small balloon over the end (muzzle end) of the barrel.
Draw back bolt to 'mid' position-i.e it can move easily-and squeeze balloon to void it of air. Move bolt to forward position then latch it but don't c**k the rifle. Leave overnight if necessary but normally the presence of air in the balloon will indicate even a very slow leak fairly quickly. You are testing to see if air is escaping through the barrel and if it is, means that the exhaust valve needs attention.
Good luck-leaks are just SO annoying.
