    FX FX King berserk Fps

    That's why cages have to be rattled. Just spoken to one of the more established "technicians" at SGC, and he knew what the problem was straight away. Exactly as somebody commented earlier.....bent valve pin. I'll keep you updated. Thanks once again everyone.

    FX FX King berserk Fps

    That's where it is now. I understand your comments. I have known them since they started down in Paignton and have always had a good rapport with them......BUT cages have to be rattled to get results.

    FX FX King berserk Fps

    That sounds like good advice/explanation. I'll pass you comments on to my RFD. Thanks very much everyone.

    FX FX King berserk Fps

    I was surprised, but there was no noticeable difference in the POI. A big difference in the rifle's report, and air consumption,

    FX FX King berserk Fps

    I wish I knew. No doubt all will be revealed in the next 24 hours. If not, this maybe a time for a rest from FX. Because of the King's weird high/low/high/low FPS behaviour, with nothing in between, it seems to point to a straight forward mechanical issue . FX's QC needs a serious overhaul...

    FX FX King berserk Fps

    It's not the chrony.....the RFD was getting similar sets of readings. I am not convinced that their technicians are up to speed (excuse the pun) with a lot of the FX problems. My POI was unaffected at my zero range of 43m. I'm sure that at longer ranges it would be affected. The rifle is back...

    FX FX King berserk Fps

    Absolutely....even opened a new box. It's strange, the FPS doesn't go up or down erratically but jumps to the exact programmed lower FPS, then jumps back up to the higher level it seems to have set itself, and is super consistent when there. There are no in between stops. Seems to me that a...

    FX FX King berserk Fps

    I've had the King for a month or more and it was superb from the word go. What is strange is how it reverts back to it's original FPS for a few shots and then jumps back up by 80 FPS. The "gunsmith" here in the UK replaced the regulator saying that was the problem. Wrong!! It was still the...

    FX FX King berserk Fps

    I have recently been singing the praises of my Fac King's consistency and accuracy. Have been using Zan 25.5 slugs at 920 fps with an extreme spread of just 7 FPS. Yesterday it jumped up to 1000 fps for several very consistent shots, then dropped back down to it's tuned 920 fps for a few again...

    Fx m4 vs fx king discussion!

    I have had 3 Impacts and been generally pleased until the MK4 started to give erratic first few FPS shots. Switched over to the King FAC. Extremely consistent and accurate at ranges out to 150m. The only downside is that it's a bit of a lump to carry around all day. The King is a superb long...

    FX FX King 600 vs FX Impact M4 Sniper in 0.25cal

    Unfortunately I can't make the decision for you. All I can say is that the King gives me total confidence, and that counts for a lot. Believe me I am an ultra fussy sod. I understand from the UK importer that they are nearly there with the MK4 's warm up problem! This should never have been the...

    FX FX King 600 vs FX Impact M4 Sniper in 0.25cal

    I can understand your reservations, but that can apply to any of the FX range, but thankrfully most problems are solvable. I am in the UK, and very close to the main importer. I have been back to them several times with Impacts, but never with the King.

    FX FX King 600 vs FX Impact M4 Sniper in 0.25cal

    I have had a few Impacts. No real problems until the MK4 variable FPS reared it's head. Switched over to a 600mm King. Super accurate and super consistent. Zan 25.5's at about 920 FPS all I need out to 100m. Don't see too many gripes about the King on the forums. BTW.....easy to tune. Start on...

    Why can't FX do this? Crap QC......again.

    FX fx impact m4 first 10 shots are slow

    I think the problem is as stated, the valve rod needs polishing. Getting mine done next week by the UK importer (who happens to be a friend of mine). If that does not resolve the problem, then with a certain degree of reluctance, I am switching over to an FAC Huntsman!!!!

    FX fx impact m4 first 10 shots are slow

    Put nearly a 1000 pellets through my Fac Mk4 and still the same problem. It has been back to the dealer / UK importer 3 times and even they are at a loss. The one thing I would say is that the accuracy is still brilliant. FX need to understand what QC stands for. Hope they read this..... highly...

    FX Crown first shot hot

    Had a similar problem with my new Fac Mk4 Impact. The first shot is always 20 to 25 FPS slower than the rest of the string. Throws all of the performance figures out of the window! Take it out and the standard deviation is always 5 to 8 FPS, which is excellent. AND that first shot drop in FPS...
