FWB 800 Junior

[davyboy30]

I have an FWB 800 Junior 10m rifle, and due to problems with cataracts I’m finding it difficult to use the diopter sights. Does anyone know if the power can be increased to sub 12 ft/lbs?

The rifles in standard Match format are already sub 12ftlbs and running at around half of that power. I presume that you want it to be closer to the 12ftlb mark (which I believe is difficult to achieve). On that basis here's a copy of my contact with FWB regarding similar.

Q : can the Muzzle velocity of the Rifle be increased at all, even if by a small amount. If so, is this something that the owner can carry out, or are the services of your UK representative required.

A : the muzzle velocity can slightly be increased. For doing this the action will have to be taken off the stock. If the rifle is in shooting direction you will find in the rear section of the trigger housing the firing pin screw beneath the absorber tube (see attachment). By means of this screw "B" the muzzle velocity can be adapted a little. Screw "A" secures against independent twisting of the firing pin screw. Loosen screw "A". Set the velocity - turning the firing pin screw clockwise will increase the muzzle velocity - turning it counterclockwise will decrease the muzzle velocity. Please note: if the firing pin screw is screwed in too much the firing pin will open the valve and the compressed air cylinder will deflate air. As soon as the muzzle velocity is set tighten screw "A" again.

As far as I am aware there are a couple of specialists out there who can modify the 800 series for 12ftlbs but TBMK they need to change a few parts to do so. I believe that FWB themselves had problems doing it on their own rifles in the factory (for an extended period of time as far as I am aware).

HTH, Vic Thompson.

Thank you Vic, you’ve been extremely helpful. My original question wasn’t very well worded, but yes, I wanted to see if I could get it nearer the 12 ft/lb mark, but it looks very much like it would be better left as it is. Many thanks again for taking the trouble to enlighten me on the work involved.

davyboy30,

There is much on such types of conversions here, in very good detail - it looks quite involved !! :

The rifle is a P70, but the principles remain the same.

Have fun & a good Easter

Best regards

I had an 800x that I had converted to sub 12ft lbs by Jon Harris , I wanted it for BR but it never quite got there .
If I had my time over again ,I wouldn't spend a small fortune on conversion of a 6ft lb to 12 ft lb air rifle .
That's just my experiance and opinion and there will be people who have had conversions done and are extremely happy with the gun .

Why? its a superb 10 mt match rifle , designed for the purpose, there are loads of FT rifle about if you want one, use it or sell it as a 10 mt match rifle.

PS, Incidentally some years back when the NSRA were considering allowing match air rifles to be used for 25 yd prone (shame it never happened!) my wife shot a standard Walther LG300 6 ft lb match rifle at 25 yd prone as an experiment to see how it compared at 25 yd with her .22rf, and shot similar scores to the .22 including a 99 ex 100. So why mess up the accuracy?

Have Fun
