    Tuning FX Impact Mk2/M3 - slower first shot - no reg creep - quasi-scientific analysis

    Too much to re-type what has already been said many times in this forum, hours and hours to read, no shortcut for anybody. To recap - the hammer is not over riding the Valve at cold shot. There are many things to troubleshoot in step by steps, either you diy learning curve or pay the bill, and...

    EDgun Edgun Leshiy 2

    I had to go back to my PC to check the old pictures, I got my L2 in Aug.2021. Back in time that was a version before REPR, because when the L2 arrived to my hands next week I paid again an extra to get it "up to dated". Here I must say you never "read the manual" ??? It says there in the booklet...

    EDgun Edgun Leshiy 2

    I don't know what is that "Apex" thingy but if gives you trouble easy to swap back to REPR or EAR or whatever was the original Reg (this how I call it). Looks like you spent some larger chunk of cash on that your project but have an issue with tuning it? Try elimination troubleshooting step by...

    Sightron S6 field target

    I have a Falcon X50T (X504LR - long range target) and seriously considering getting the T50i next. But again the Sightrons are more a US market thingy.

    EDgun Edgun Leshiy 2

    First and most important thing is - the speed kills the accuracy no matter what caliber or barrel length. I can't speak about tunes for .177 with a dog bone and definitely raising eyebrow when you saying "consistency is a laugh. At 130bar, 1.0 x 1.2 jets". I am shooting rings only with my L2...

    EDgun Leshiy 2 Repr air leak after fill probe oring burst

    That plastic ball is ABS can crack or break but cannot disintegrate or grind down to a powder. You better inspect the airpath holes and corners if you can recover any plastic chunks. I tried the metal "pearl" balls and didn't like it. The plastic ball have a molded counter-bored pocket for the...

    Looking for diy ideas - adjustable rear rest

    I asked UPS to email me the receipt, visited my customs office at the cargo airport 45 minutes away, paid the tax and emailed the stamped Invoice back to UPS. Got this PQP rest delivered today, all look good and I saved myself $94 from UPS brokerage fee. And from now on, nomore purchasing...

    EDgun Leshiy 2 Repr air leak after fill probe oring burst

    A full set of oring kit in the drawer I would recommend to everyone. If you remove any part that has orings, replace all and lube well before putting it back.

    FX Impact M3... loss of power

    If the Impact was sitting for a while, there could be any of these common scenarios: - a Reg creep, the hammer cannot over ride the raised pressure in the plenum, it needs 5+ blank shots to balance the valve; - check the C1, can possibly get loose. Check the Hammer set 6mm; - check if air blows...

    FX FX Match Grade Trigger?

    Nothing wrong with the Impact MK2 trigger for shooting target. I polished to mirror finish all sliding surfaces and lubed with moly grease. When I am pulling the blade if I pay attention I can feel the springs rubbing against the adjustment screws. Butter smooth.

    FX Impact M3 ... POI change journey.

    I am shooting my Impact 100 meters rings BR, and that distance is a benchmark for myself. I never had an accidental PO shift in four year and over 20K shots. Liners floating on orings, barrel floating on orings, yes I replaced those to NBR 90 all of them. I toke it apart milion times doing some...

    FX Fx impact compact .25

    I am shooting .25x700 variation of liners 100 meters BR rings. Tried for more then a year any slug over 10 K shots in between 37-41-44-46 gn and me back to 34 gn JSB MK1's. This up to 100 mM rings, again... Also my view about replacing or upgrading the gun CF bottle - for the money I chose...

    It doesn't work that way ;) just to give you a credit for your comment... I am speaking 5-6 (especially after couple beers in a company) and literate in 4 languages from mid East EU and Balkans, google translate is somewhat friendly with these but mostly loosing the context. Imagine now a non...

    FX FX DRS with low velocity first shot! What should I check?

    Several months ago I started with 2-3 small drops of PTFE oil in the air line, after several refills or topups this shall be good enough to lube the internals especially the Valve Rod and orings. Last time I polished the MK2 Reg pistons - according to my pictures taken - somewhere back in 2021...

    FX M3 Consistency After a time stored .. From an FX Hater ( Not )

    The Impact was sitting in a locker over six months winter time without recirculating the pressure. Polishing the mating surface between two piston parts - especially around orifice - will do. With 3M polishing cloth, I bought and used last time back in 2021. Every oring I remove from its...
