Welp its sad to say i bumped my m3 and now it wont zero, even when i try to rezero at 40 yds my windage is maxed out and not allowing me to make anymore adjustments….what do you guys look for after bumping your impacts?

Also check the picatinny rail as it has a bit of play in it so it can be adjusted left or right once the screws are loosened. This small adjustment makes a HUGE difference in your POI.

Couple things to try.
Reseat the barrel. Loosen the 3mm, pull it, put it back in, tighten back down.
The scope rail--2 x 2.5mm in the rear and 1 x 4mm in the front. Break these loose and make sure your scope rail looks like it's lined up centrally. The tolerances aren't so great so it's very easy to have you scope rail be mounted off-axis.

Welcome to the FX world! Count the parts in the barrel assembly of that rifle, and you shouldn't be surprised that it's a bit fragile.

I would say any hit that makes stuff move to the extent the original poster is explaining….wouldn’t be heathy for any pcp.

Now that i read all your guys suggestions, im thinking its my scope rail possibly.
i didnt see it bump my barrel but i know for a fact it had contact with my scope.
im running the eagle vision adjustable 1 piece mounts, right away after the bump i pulled the shroud off and tried to reseat it and re mounting my scope but it didnt fix the issue.

Try pulling the barrel, take the shroud off then roll test the barrel on a flat surface. I’ve swapped 2 of my guns to the eagle vision mounts because I like the adjustments. What scope are you running? It usually takes a pretty decent hit to mess one up unless it’s a $30 tasco/Simmons.

@cranky1 the barrel or the liner by itself?
im using a element optics helix, it wasnt a crazy bang. It just tilted over onto its side.

Can't be anything serious. Not like the guy who criticized FX guns for being flimsy, but said he forgot it on the tailgate of his truck and drove off. Really?

I would look at the rail like Moistone suggested. I noticed how poorly designed that thing was the first time I took the gun apart. Like someone mentioned, they are not stout guns and the longer you own one and mess with it, you make mental notes on its weaknesses. You just have to develop procedures to overcome some of them and live with others.

I'm not familiar with your scope, or the mount, but changing them out and testing with another would for sure be something you should do. It doesn't sound like the bump was enough to have this result, but it sounds like the scope and mount took the impact, and not the barrel assembly. If that's the case, and in spite of my preference for other designs, I doubt the barrel is the issue. If the scope mount was moved enough for such an extreme shift in POI, I believe you could probably see the misalignment with a close look.

Sorry been on the road all day, I would check the barrel(part that has liner inside) by roll testing it. When my dad shot archery he would spin test the arrows, he also made an arrow straightener. You would put the arrow in and it had rollers about 8in apart with a gauge in the middle. You would roll the arrow in it and watch the gauge, it also had a handle that you pushed down to take some of the bend out. This was before carbon arrows, we also numbered the arrows for consistency. But this is all old school stuff. It didn’t take much for the arrow to be considered junk.

Banged the hell out of my EvoL hps barrel a few times. Never had to re-zero. Smacked it on a chair, and even my sliding glass door as I attempted to sneak out the back.

You’re comparing a tank to a wind chime, not fair. Having all those barrels, goodies and gadgets to play with comes with a price, some can live with it some can’t. The challenge I’m currently interested in is making an Impact more durable and consistent. It’s been a bit of a journey. Not giving up yet.
