    I bought a set of fx no limit mounts to fit onto my sub12fpe impact as I was unsure of what height I would need to get correct head position. As it turns out, the lowest they would go was just fine.

    Anyway, last week I decided I would do some long range shooting, and although I have plenty of vertical adjustment on the turrets of my scope I ran out of adjustment before I was able to zero.

     

    Today I thought I would have a go at using the adjustability in the mounts to get distance without maxing out the turrets. Initially,  found the adjuster too sensitive but I then noticed this small hole in the bottom of the mounts 

     


     

    so out of curiosity I took the scope off and found the hole was M3 tapped part of the way through. I put a M3 x 8mm grubscrew the wrong way around into the hole from the scope side. This allowed fine adjustment it’s a 1.5mm Allen key.

     


     

    with the clamp screw done up fairly tightly I was able to fine tune the zero this was no more difficult than using the scope turrets.

     

    well done fx, two thumbs up from me but why there was no grubscrew or any mention of this feature in the instructions is a mystery to me.

    Greenballs to you Bucketboy! Wow, I have the FX no limit mounts on two of my guns and never knew this? I was using different thickness's of paper to serve the same purpose as that grub screw does? LOL What a game changer!

    Haha, great catch BB. I just checked the set on my Impact and sure enough they have them as well. I guess in the excitement of a new gun and rings I never looked at the detail of the rings. As Umair found, my set of dove tail NL rings didn't have it also. The Sportmatch adjustable rings in the dove tail style does have them though. That's what I'm using on my Crown and one of the selling points that made me decide to go with them over FX's for that application. Thanks for sharing your find..

    Sportsmatch adjustables have had this for a while. My FXs do not. Fx must have recently copied SM in this. I still prefer the Sportsmatch mounts.

    Thanks for the replies, so it looks like these are a new feature on the no limit mounts but they haven’t amended the instructions.

    And the SM mounts have a locking screw in addition to the vertical adjusting screw (2 left and right adjusting screws, 1 height adjusting screw, and 1 locking screw).  Not sure how much more solid it might make the SM in comparison to the FX, if any,  but it is there.  I also really like the SM mounts and have multiple sets.

    I initially had a problem with the FX mount moving under recoil. I had them on a Walther Terrus that has a lot of droop. I solved it by cleaning mount surfaces with brake cleaner and putting a dab of blue loctite on the surfaces. Hasn’t slipped since. I’m going to look at them to see if they have the screw hole next time I visit. Rifle is at son in-laws place.

    Just saw this post – very timely for me because I will be getting a set of the FX rings for my Impact and was not sure that they would be the right height.

    When looking at the FX Accessories on their web site ( https://fxairguns.com/accessories/fx-no-limit-scopemounts/ ) I saw mention of the adjustment screw and that it was only available on the picatinny mounts…

    Picatinny version offers an adjustment screw in the bottom which allows easy height adjustment.

    Thanks for posting the pictures as I can see what they are talking about!
