Thread: Air rifle tune up

  1. #1

    Air rifle tune up

    just got my hands on a bsa goldstar air rifle. its pretty much unused and hasnt got a mark on it. It reminds me of my hw77 in terms of weight and balance and build quality.
    When ive shot it it kicks like a mule and makes a real twang accuracy is so so.

    I doubt the spring and washer has done much work so i'm torn between taking it apart and giving it a good lube and polish or fitting one of those venom kits. Ive read the kits reduce recoil and smooth everything out but you dont read many negative reviews in the gun press.

    Anyone fitted one of these? Worth the bucks ?

    I had access to a Weihrauch (not sure of the model) which had one of these Venom kits fitted.

    I have got to say that it made a tremendous difference. I do not know how much was laid out but he did the work himself and it was like a new rifle. It was very smooth with absolutely no twang from it. It was incredibly accurate also but that was after experimenting to get the right pellet which would apply to any airgun.

    It is worthy of note though that the circumstances were similar to your own and the previous owner had "stripped and lubed" which was detrimental as this causes "dieseling" which I was told is like the spring "shuddering" when it goes forward

    I have just re-powered my HW77K.

    It had an ox spring fitted and the associated twang.

    I stripped it down with the intention of fitting a V Mach kit. This was 73 plus delivery. I opted for the OEM Weihrauch parts. Spring, piston seal and breach seal came to 24 from my local gun shop.

    The thing that made the biggest difference was changing from Eley Wasp pellets to H&M FTT. It now shoots very tight groups at 35m. I accept that the V Mach kit may be a slight improvement but I now have a gun that out shoots me with no twang.

    I must admit to be dubious about OX springs. Had my feinwerk Sport Model 127 re-sprung some years back as despite askign for a OEM spring the idiot at the gunshop fitted an OX one. Noise went up accuracy went to hell in a hand basket. Later had it re-done by another shop and it's back to like it was when new.

    I had the full Venom Lazaglide tuning carried out on my .20 hw80 and boy was it worth it.
    Lovely to shoot and the rfd that i deal with was surprised at how quiet it was even to the point of taking two squirrels with consequetive shots.

    So I'd say yes it's worth it

    Stick a tin of pellets through it before you decide, it might just be ok after having the cobwebs blown out of it! I got a barnfind webley omega and the more it gets used, the better it gets

    That said, I would like a full Venom 80, walnut stock etc.

    I fitted a maximizer kit to my HW77K, transformed it. ROBB'S do lots of air rifle tuning kits. Best thing is to use the correct lubricants, moly grease the spring and sleeve it cuts down all the twang. Ox springs not the best choice, stick to the standard bits which are readily available from J Knibbs.
