As crazy as it may sound a know someone looking for a UK / sub-12 version of a M4.

Various reasons.....so far the importer suggested turning down such a rifle to the less than 12 fpe. However, there are several simplifications on the UK version that make it desirable to this individual. EU suppliers deal in FAC versions / or cannot ship the US. Anyone ever try to 'special' order a rifle directly through FX and the importer? If memory serves I think i read of someone getting the last Crown in a walnut stock in such a fashion. Took a while but he got what he wanted.

I appreciate any insight,

Why? All of U.S. customers want large caliber high power rifles and the market for what you want is infinitesmal. I suppose there's no reason why you can't take an Impact and de-tune it to what you want, but there's no guarantee of the results. I suppose the major difference is in the regulator and hammer guts.

Yup , why you have a big selection there / outside the USA but not here.

Nobody even ask or questions this on your 2ed rights more infringement and best part is this is not even considered a firearm too boot ..

God bless America..lol ( whats left of it anyway)

It isn't like FX isn't making this rifle. Just s=trying to secure one in the US.

The belief is that a gun deigned for sub 12 is going to do it's job at that level better than one designed to shoot at max power. Detuning is not the same. The two rifles have different guts.

Bigger is not always better, or more appropriate.
 
I am pretty sure Krale don't sell FXs. UK shops wont ship to the US, so either it is get one there or alternative try getting in touch with FX directly and see if they can slip one in the next container to Utah Air.

Thanks
 
strange - when I go on the US section of their site no FXs guns show up.
probably because they don't ship FXs to the US

see: Krale's FX shipping policies
Ok I see what your getting at . I guess with that lawsuit and all with the USA dealer it's a no go today on one ?

With that funny business fx would be a hold of buy till it's fully settled and a firm dealer / distribution/ importer is in place

I guess this thing

I am the one who is looking for the UK sub 12 Impact.

Why? Because "I" want one.

My current .177 M3 has the 1st reg at 100 bar, the 2nd at 25 bar, the Macro at 1, the Micro at 2.3, the air valve at 3 and with H&N 9.57 grain Baracuda FT I have now shot a 0.191" E to E 5 pellet group at 20 yards indoors. The FPE is 11.8 to 12.2.

I want to go for a possible record of 0.188" for <12 FPE at 25 meters and I would like to do it with an FX Impact.

Welcome to HAM, does your impact have any functional issues running so low? Curious!
 
Got one coming.

Corrected it for you. LOL
Went through some hoops to get there but in the end, once he proved to FX that what he wanted was only possible by going to HQ in Mariestad they acquiesced.

Now you wait….


Thanks for everyone’s input.

Happy Thanksgiving
Glad it turned out this way. Let us know how it is vs the tuned down 'HP' version!

I spent all of October 2023 adjusting this .177 M3 Standard Version to shoot the tightest groups possible.

Here was my process:

1. Purchased from Pyramyd Air one tin each of every weight diabolo wad cutter and round nose pellet available from 7.0 grains to 10.3 grains. If a pellet of different diameters existed for the same pellet and weight, I purchased 1 tin of each size available.

2. Left the first regulator at factory setting and adjusted the 2nd regulator to the mid point of the hi/lo range stated in the manual.

3. Set the Air Valve (AV) to 1, the Macro (MA) to 1, and the Micro (MI) to 1.

4. Shot two 5 round groups for each tin of pellets, indoors at 20 yards using a TargetShooting.com 1000LP rest.

5. Repeated step 4 with AV at 2.5, MA at 8, and MI at 3

6. Repeated step 4 with AV at 4, MA at 16, and MI at 5

7. Preliminary Results: One 7.0 grain wad cutter and one 9.57 grain round nose of a specific size grouped the best of all the pellets in steps 4, 5 and 6. The others produced large groups. There was NO vertical stacking so a harmonic tuner would be of no use for this barrel - pellet combinations.

8. Set the AV to 2.5, MA to 1, and MI to 1.

9. Shot two 10 round groups each for the 7.0 and 9.57 grain pellets. 1MOA at 20 yards is 0.2094", was looking for a tune that produced a 10 round group of < 0.2" edge to edge.

10. increased MI 2 clicks and repeated step 9.

11. Repeated step 10 until group size was < 0.2" (0.199" to 0.195") E to E.

12. Settings for 9.57 grain round nose diabolo: AV = 2.5, MA = 1, MI = 2.3. For 7.0 Wad Cutter diabolo: AV = 2.5, MA = 1.0, MI =1.3.

13. Attached FX Pocket Chrono via FX Chrono attachment rod and shot one 10 round group for each pellet - setting combination, then increased the AV 1/2 turn and repeated the process until the AV was at three. Velocity increased, FPE increased but group size was not changing and remained < 0.2" E to E.

14. Decided < 12 FPE would be interesting, so final setting was based on the 9.57 Round Nose so I could shoot 20 yards sub MOA indoors and outdoors. Final setting: AV=2.5, MA=1.0, MI=2.1.

5 round Group size, when using bipod and right shoulder, has been consistently below 0.2" E to E at 20 yards indoors when I am in the zone. My best to date is 0.191" E to E. The rifle is super quiet and super smooth to shoot. Looking forward to finding out what an Impact actually built to be sub FAC <12 FPE can do!!!!!!!
