Bsa ultra jsr

Recommended Posts

I have bought my daughter a bsa jsr for Christmas. I was wondering if there is any way to ease the cocking of it. She is struggling at the moment. Thanks. It’s the 16 joules version.

You could lighten the hammer spring tension to minimum but it wont make a huge difference. To the effort .it will drop the power a bit though to id guess around 9 fpe  

An easier option might be to fit a bigger rear bolt to the action it gives more to grab onto  

I suppose a lighter hammer spring fitted would also help ,though this may throw off the efficiency of the valve and consequently shotcount  .

hello, i would not tamper with internals , maybe a longer loading bolt handle or even a straight bar handle so more leverage as long as it loads and rests in same position, would not take much to make one suitable but you might need to cut off the original handle unless it screws in , if not cut off handle drill a tap hole of appropriate size bar and refit, i had a look on google for any BSA straight bar loading bolt handle , i am sure there are made some where,

I had the same issue with my son years ago. A metal work engineer friend of mine create an over size extra long bolt for my scorpion. It’s looks a bit different but does the job due to leverage. If you want it, you can have if you can cover the postage.

To be honest the best solution is what u have found .dont mess with the gun ,just persevere and grow to manage it  

You should see my son pumping up my 1377 pistol carbine .he has found his own technique  and  can pump it to about 5 pumps .which is plenty and gives him the  independence to shoot by himself  .

(With some supervision ofcourse)

Type in Bsa bolt handle on ebay theres plenty on there. My ultra se was tunned by Darrin Xtx Air and tgat made all the difference the the bolt pull weight. However fitting a big bolt ball bolt off ebay or Xtx Air or Rat works will help alot.

You do realise a left handed bolt .wont make it work left  handed ? 

The bolt  always has to be rotated anti clockwise before it  can be pulled backwards .and the weight of the bolt knob (in its right had configuration) helps combat bolt jump on firing .

So if you  had it on the left the weight of the knob would drift the bolt downwards and potentially the whole bolt would blast backwards on firing . (Not good )
