Customized, Modified Rifles & Repairs
This page: Crosman 38T revolver pistol. Marlin Papoose .22lr Bipod. FX Revo PCP .22 Norica Titan .17
I have an engineering background (18 years) and I've customized and repaired many rifles and pistols over the years, rim-fires, air-rifles CO2 and pump-action- modifying and making parts such as suppressors, threading, sear springs, torches and lasers. I thought it might be useful to begin photographing and listing the new items, mods and repairs - just in case it helps someone else.
I've decided to mod my Norica Titan .17
air-rifle.
Work done so far - 3-9x32 optics. Two piece mounts. Polished trigger mechanism. Remington folding bipod.
Threaded to standard 1/2"UNF for 25mm - allowing secure fitting of a suppressor from which you can cock the rifle.
Next on the list - I will make a full over-barrel suppressor with inbuilt muzzle-brake.
Check back for more photos.
Instructions for attaching folding bipods to a springer.
Work out where the center of balance is on your rifle, as you don't want your rifle falling forward all the time!
Make
sure this point is back far enough to allow your rifle to be cocked.
Purchase a Sling Swivel Stud - and drill a 3.5mm hole to screw it into.
Screw the Sling Stud into place, take it out again and cut about half the thread off (stops the cocking arm hitting it)
Attach your folding bipod to the stud.
Email me if you are still unsure, or better still - come and see me.
You should be able to purchase a Remington Folding Bipod for $99
Do NOT use those cheap plastic bipods that fit onto your barrel - they ruin accuracy!
Now for the BIG question - do bipods ANYWHERE on your springer ruin accuracy???
Well - my expertise is not springers, but I have done some field testing with the bipod, and without.
Although hard to see in the photo (left) - allow me to give you the results.
15 meter accuracy test FREEHAND in prone position.
10 shots - grouping of 46mm
15 meter accuracy test WITH BIPODS extended - prone position
10 shots - grouping 23mm.
Again, I am not used to shooting springers, and I would like an expert/experienced shooter to replicate this test, but as far as I can tell, at least my shooting (novice springer) is enhanced with a bipod.
Here she is - finished!
Full over-barrel suppressor with inbuilt muzzle-brake.
True, the suppressor is mainly for aesthetics (show) - but let's be honest, it looks darn nice!

Dave's FX Revo .22 Mods
Custom Bipod and Suppressor
Dave contacted me - wanting me to make a custom suppressor for his FX Revo .22 PCP - partly because it needed to have a recessed rear to accommodate the adapter, and he couldn't buy an over-the-counter silencer to match the same diameter as the adapter.
We are both pretty happy with the results - especially the gloss black finish. Although it might not give him much better suppression than his previous silencer, it sure looks a lot better!

Dave's pretty skilled himself, and made this custom adapter for his bipods.
Nice work Dave - and that's one beautiful rifle!
Cheers, and hope to see you around. Roger.

Crosman 38T CO2 6 shot revolver
GETTING PIMPED!!!!!
May 2008
I had one of these as a teenager - but in .22. It wasn't powerful enough so I sold it. I have been looking for a .177 version for quite a while.
This revolver was bought new by Dave Martin (yes - his real name) around 23 years ago, mainly to dispatch the occasional possum on his farm. Dave had the wooden hand-grips custom made by a professional wood-worker around 15 years ago. Since moving to the city several years ago, this baby has sat in the cupboard - waiting for me to buy it. I bought it for $160 - April 2008.
What's even better than the beautiful condition and the wooden hand-grips - is the awesome holster.

Now the fun begins!
Thing is, that I charged my revolver with a new CO2 canister, and while everything worked well - there is a leak in the system, requiring a full overhaul.
So - while I'm at it, I might as well have some fun!
My goal :- Fully strip, polish shine and recondition my revolver - and at the same time modifying it to reach a velocity of around 1000fps - or whatever maximum velocity can be obtained from a CO2 cylinder - even if I only get 6 shots from it!
(At the moment I would estimate it shoots around 450 fps).
Once finished, it really should be a fast shooting possum busting pistol!!!
I can't wait to make this happen.

Stage
1 (right) - strip the unit and lay-out carefully to aid in reassembly.
The first thing I noticed, apart from the quality of material and craftsmanship, is that the main brass CO2 feed tube connecting the CO2 canister and the firing chamber has almost worn through and needs replacing. Apart from that, everything is in excellent working condition with minimal wear. This baby will be as good as new once I've finished with it. Actually, it will be BETTER than new!!!
Stage 2 (left) - using a paint stripper - carefully strip and wash the main parts of the pistol.
This is a beautifully made and engineered pistol. They really don't make them like this anymore. That being said, there's always room for improvement and modification. I intend polishing all the firing and trigger mechanisms while it is stripped.

Step 3 (right) - Carefully polish the alloy body parts with a polishing mop and soap.
I think you'll agree - it's already looking pretty nice :-)
I can't wait to get into the custom modifying of the CO2 firing chamber and springs!!!!
Here's the finished beast!
I think she is beautiful.
I'm just waiting for my new chronograph to arrive - to test FPS

Marlin Papoose - Bipod Modification

The challenge with a Marlin Papoose is that it is a take-down rifle, and you can't put a bipod on the sling swivel like other rifles.
This can be overcome by using a Weaver Mount Bipod mounted to the underneath of the stock, fastened with the trigger guard screw (Approx 5/32 or 4/1.25mm thread) and by filing a rectangular groove into the plastic stock, as in the photos below.
Why put bipods on a take-down rifle!
First: To increase stability for longer range shots.
Second: To protect the optics from damage.
Third: It just looks cool!
1: Strip rifle, unscrewing the two holding screws. 2: This is the Bipod to be attached.
3: Position Bipod and draw around with marker pen. 4: Saw two lines to a depth of around 3mm and use file to make channel.
This is my cat - who thinks she is a dog and follows me everywhere!
5: Tidy channel and ensure tight fit with bipod base. 6. Using the same screw, fasten bipod into position, using a locking washer

7: Make sure the bipods fold away from the barrel- to enable short takedown length.

Nice job, well balanced and practical.
The only difficulty is that the bipods must be activated in order to clear the trigger and fire the rifle.
A small sacrifice for a greater gain!
