Anyone use the £100 BEST Fittings Quick Fill Upgrade Kit - on a Theoben Rapid MK2?

Has anyone used this kit and if so, would they recommend it for a Mk2 Rapid?

I guess the Mike Tawn Rapid Quick Fill System - Regulated "V" type, which replaces my Mk 2's regulator would be a more 'complete' solution but I'm not keen on drilling the stock and as the rifle will only ever be used on a 25 yd home range, then the bottle going forward by 55mm is no big deal. However, I will be using a sling on the buddy bottle bipod ring thingy so there will be some sideways/vertical force on the bottle's attachment but not too much for this adaptor I'd think.

Any comments welcome.

The bottle on a Rapid makes it pretty front heavy anyway, shoving it 2" further out towards the muzzle is going to seriously unbalance it.
I'd give it a try with your bottle taped to the barrel allowing the gap to see just how bad it feels.

got one on one of my MK1s, fitted in 5 mins no leaks and cannot notice any imbalance with it, got a 280cc bottle on it which probably helps,got fed up unscrewing the bottle, a good bit of kit.

I've got one on a mk1 with a 400cc bottle and had to nibble about 3mm out the stock for the fit.

Not the best of pics and the cut outs look worse in the pics than to the eye.

I had one fitted to a mk2 and it worked just fine. Did have a problem after a few months and best fittings sent out replacement parts at no cost to myself. Would recommend to anyone.

Thanks for that. Surprised though that you had to do this as I thought they were suggesting that no modifications were necessary to the stock...
