Simmons Air Rifle Tuning

11/07/2026

An original Airmasters HW77 .177 that came in for some work. This rifle still retains its original Airmasters setback trigger and alloy phantom moderator along with an Airmasters brass pistol grip cap fitted to a genuine factory Tyrolean stock. A mint Kassnar AO scope sits on it, quite possibly also supplied by Airmasters , this is an Absolute gem of a rifle and now shooting better than ever 😎

A pair of Whiscombe JW50 rifles now ready to reunite with their owner. It’s nice working on something different than the everyday tunes. One of these had been shot with a dead piston seal that resulted in catastrophic failure of both piston heads as they collide with each other without any cushion of air between them. A complicated rifle with zero availability of spares. I machined new piston heads up from scratch then followed with a full service on both rifles. They now shoot as good as the day they left John whiscombe who originally made them.

And another one saved. This lucky customer picked this up from a boot sale, usual dead ram, disintegrated piston seal, ram seals as hard as nails and a cracked cocking shoe.
Now all sorted with a full rebuild along with one of my machined cocking shoe and a britseal up front it’s now performing exactly as it should be 😉

Another Theoben saved, this one an SLR98 in awesome condition. However this rifle had suffered the dreaded piston seal failure and to top it off there were 10 pellets stuck in the barrel 🤦🏻‍♂️ the superb Britseal piston seal fitted along with full ram service, cocking shoe and schrader valve replacement, it’s now ready for another lease of life 😎

Something a little rare now complete after a full strip and rebuild, new pump head machined from scratch along with a blow off valve, bent pump rod sorted along with a full seal kit and this Venom innova is back doing what it should 😎

A new out the box 97 action (sitting in my old test stock) gets a full tune along with a Rowan trigger blade and one if my Titanium oversized safety buttons 😎

Another webley Longbow finished and ready to return to its owner. These tune really well and are a dream to shoot when done 😉

Another Theoben now up and running. Full ram service along with a new cocking shoe machined and fitted. This countryman turned out a really nice rifle 😎

A lovely Olympus project I’ve just finished for a customer. This has been a slow build due to a few issues encountered along the way and fitting it between my everyday tunes and services. This came in with a barrel like a banana, and that’s where the problems started 😂 anyway the barrel is now arrow straight, a new cocking shoe made, safety catch sorted out, trigger fettled and a set of optilock 30mm mounts I milled to suit the Theoben raised scope rail. Then the action was blacked by Shaun Hill at ISP and it’s come back like a mirror. Turned out a really pretty rifle and it shoots as good as it looks 😉😎
