Zero’d at 16yards shooting very smooth then target at 35 yards 6 shots 10 mm crs with jsb 10.3 shown in photo.
Haven’t got a crono but pellet drop suggests 12.1 ft/lb sorry got that wrong about 11.2 I expect that this might increase slightly as gun settles in. Pleased with the mods done a much nicer feel. Edited by Stuart - 21 Jul 2023 at 3:21pm |

Offcut of 30dia x 150mm Nylatron from LEP Plastics Chch $10
O’rings Pacific seals Wellington total of 6 for piston and breech 2 sets of each for spares total $7 Nylatron specs The closest to Oilon Nylon is Nylatron GSM which is specifically formulated with a molybdenum disulfide (MoS2) additive. This additive provides enhanced strength, rigidity, and self-lubricating properties to the material. The presence of MoS2 particles helps to reduce friction and wear, making Nylatron GSM well-suited for applications involving sliding or rotating parts. Guy in Uk been using his setup for about 3 years with no trouble at all with extension and theViton o’ring So I will have to get out and do some shooting and see how mine goes.

There ya go.
I'll be interesting to see how the O ring setup goes for you. Good work! Would a quick blast of heat get rid of the stringy bits? Where did you buy that material from?

I had a look and can't see any restrictions on your profile.
Maybe Nunga will check, he knows heaps more about it. I can see you have a couple of images uploaded, but can't see them or when you uploaded them. |

Just got finished and Prosport is much better no spring twang as with the old loose spring guide
Turned a nice tight one up in Nylatron as are the piston extension and top hat, a slight radius was required on Seal undercut to allow fitting of the extension also needed 4 slots to allow expanding to fit a good tap with My tapometer so this is a nice tight fit. A bit stringy to turn but pleased with results and new seals now a lot cheaper and easy to change. New breech o’rings aswell. The spring isn’t standard so would like to get one as this one seems a bit strong but Will see how it goes 31coils. Hello I will get some photos on. Shimmed side play in trigger now much better Piston extension 17.5mm Copied what a UK guy did but used existing undercut and didn’t need to use securing screws. https://nbroadsman.me.uk/index.php/air-rifles/air-arms-tx200-hc-tuning Edited by Stuart - 13 Jul 2023 at 8:49pm |
