    FX Impact Block Barrel Stop Pin

    On the FX Impact blocks for example the power block, how is the barrel location stop pin removed? Is it simply pulled out with some pliers, to replace ?

    FX STX Superior Heavy Liner Vs FX STX Superior Liner

    Reviving this old thread, has anyone experienced drift using 34gr and 36gr slugs when using the superior standard liners specifically the .25 calibre. Reason being with a 50 yd zero, the 34gr/36gr slugs seem to be drifting 1" or slightly more at 100yds in zero wind conditions, the gun has a...

    Spurious Speed Deviation - FX Impact M3

    Issue resolved, through some fault finding. Problem was my own fault, I fitted a Kraford and Lypt probe carrier, which are excellent, but I didn't check probe seating depth, the probe was only half way across the transfer port, doh !!!! Adjusted and much better...

    Spurious Speed Deviation - FX Impact M3

    I also tested at 50yds and I get a great group and then get a random shot drop 2" and slightly left. Testing on chrono shows a spurious 300fps speed drop intermittently ... Really annoying o_O

    Spurious Speed Deviation - FX Impact M3

    Why do you have to have that number, how would it explain a spurious 300fps drop on occasion ? The 2nd reg is set at 140barg, if it was set at 110barg, 130barg or 160 barg, it should not do that, the hammer is in no way maxed out, and it's not going over the curve and dropping back off in power...

    Spurious Speed Deviation - FX Impact M3

    Anyone had issues with there Impact M3 randomly dropping speed, not a small amount, the fun is tuned to 960fps - 292 m/s for shooting slugs but every now and then the gun will drop to around 640fps - 195 m/s are around that mark, then back to 960fps - 292m/s for 5-10-15 shots. I've removed the...

    FX Impact M3 Sniper .25 700mm Erratic fps

    Alright Kev, you could of just wound the valve stop out further to allow more travel.. just a quicker way than adjusting the hammer seat... Good to have a few breech seals handy too, has your FPS spread resolved itself now.. ?

    FX Impact M3 Sniper .25 700mm Erratic fps

    Hes already stated he has re-installed the original hammer weight and is still having issues... I also have an M3 and I can relate to the inconsistency and spurious wild spread on a random shot...which led me to delete the 1st stage regulator, although I'm still having issues... my Mk2 are...

    FX IMPACT M3 .25cal

    I found the standard 700mm superior liner vastly better than the superior heavy liner... Put the superior standard back in and re test... it shoots H&N .25 slugs great..

    M3 vs M2 Valve Adjuster

    I own an Impact Mk2 and also the Mk3. Using the Mk2 the valve stop has much more adjustment before it affects velocity, I leave it on line 4 and sometimes do not see any velocity drop until I get to line 2. Whilst the M3 I have to leave the valve stop out way past line 4, maybe like line 5 if...

    Kraford & Lypt Delete the Reg

    The M3 is doing strange things, also I noticed groups opening up the closer it gets to the 2nd reg pressure, Mk2 impacts did not have this issue. I was checking a zero at 40 yds the other night and it was slug on slug, then a shot threw 4" high on two occasions, all be it I was shooting faster...

    Kraford & Lypt Delete the Reg

    Has anyone removed the 1st stage regulator from there M3, I have no confidence in it, I'm sure it just does what it likes and causes problems with consistency at certain pressures, the Mk2 models were fine with a single regulator...

    FX Impact Probe Alignment

    Yes I have a Mk2 and Mk3 impact and on the Mk2 the probe carrier has always appeared to sag slightly lower than the Mk3 . This causes the probe to slight catch the bottom of the transfer port before being guided in... I was thinking of maybe adding a small piece of brass shim on top of the block...

    FX Impact Probe Alignment

    Has anyone had issues with the Impact probe sitting too low and not going into the transfer port cleanly, if the fun is tipped upside down it aligns correctly wheck cocking and cycling the probe, but in the normal position it catches the bottom of the transfer port and is guided in. Did you have...

    .25 slugs

    Try some H&N 36gr slugs in .249 or .250 with a 700mm superior standard liner at around 930fps (56 shots per fill) and 960fps (30 Shots per fill) and you will be VERY impressed.

    Power Plenum on .25 cal., 600mm slug liner and 33.5gr NS slug

    They are master salesmen, they have multiple youtubers all pushing there products and now scopes... whilst the FX rifles are excellent, they overhype stuff massively . Take for example there new scopes, go buy a Sightron S-Tac and save yourself a heap..

    Uragan windage out at range

    So how would you prevent or reduce spin drift ? Also it seems the uragans and vulcans are prone to this, whilst the impacts I have tried with 45yd zero and then shooting at 100yd distances and with the same pellets are not.

    For those with the fx power plenum

    Use the original hammer spring.
