N/A Barrel Droop

You can. Remove sights and stright edge ( 36") off the barrel block look at widening from the block out to the muzzle or tube end .

I think . If the tube part is stright and the barrel gaps wider its the barrel ( easy bend job) if the barrel looks straight and gaps along the tube it's in the lockup parts . ( Not so easy,). You can recheck without the breech seal to see if that gap improves of so maybe a too thick or thin seal ..

I just level the guns tube and check barrel . Must use matched levels .

Hello everyone

Just a question, can barrel droop be checked with a straight edge? I have access to a straight edge used to check cylinder heads for warp/flatness and am wondering if I could check barrels that way?

Thanks for your thoughts.
If you suspect you have droop , look into getting a 3d printed barrel band to attach to the bottle if applicable. Long barrel guns can sometimes can benefit from support. Yes you could check it with a straight edge, but if its sitting on a flat surface it probably won't droop like it would while in the gun

Spring guns don't have a bottle...

If it's truly bent yes, but it does not have to be bent to have significant droop. I always check with a scope set to optical center.

Personally, I think barrel droop is a myth. Maybe many years ago, before modern technology, some guns were assembled incorrectly. Springers, and airguns in general, have a loopy trajectory and when shooting at shorter ranges, you run out of elevation adjustment on the scope and blame it on a bent or drooped barrel. What's needed is adjustable scope mounts to compensate for this. Or, in worst case scenario, install a 0.015 inch shim under the rear scope ring. I sure would like to be able to inspect a newer gun with accurate tools to see if this really exists. How about you expert tuners? Any comments?

Diana is by design. They see no problem with it at all 👍👍


Just to add diana ses no problem with there droop but yet

And what not showed at ham " review" .lol .

Is diana now looks to copy a hw type lock up .

My HW50 was just as bad as my Diana 48. Shame on both of them, so sad that you have to bend a barrel on a brand new $400-$500 gun, I refuse to use crutches like adjustable mounts.
I think the thinking was old days lower power the trajectory arc was big arc . Kinda mortar round so the droop built in made you use the "artillery hold " we hear a lot of .

Today higher fps guns trajectory is a lot more flat so that built in droop works against you somewhat.

Also dropp compensation mounts were mostly diana minded or sold to " fix" that Diana gun issue.

( Opinion,)

I thought the Germans considered themselves perfect in every way. Any half wit can see this is not good and Diana should have fixed this long ago. I have never seen an HW like this, although someone here said their HW50 did have barrel to receiver misalignment. Why does it take them so long to fix things like this? I just bought two new HW35s. No problems here. My friend has a couple of them made around 1980. They are good too.

I just so happen to have this handy 😜

( The first was could not figure out how to keep the screws tight 😉)

You must be new to these.

Barrel droop is real. So is barrel sweep

I fix stuff like this on Weihrauchs all the time. Dianas are worse.

How does one fix that?
It depends on the cause. Most often its using a known good mounted scope and bending the barrel close to the optical center of the scope.

Running scopes near vertically maxed out on springers is at the very least problematic. Scopes live much longer on springers when they're zeroed within a full rotation of their optical zero. This is another reason droop should be addressed in some manner.

Fix what? Me if hw/r new i rma it .

Money there asking today better be top notch pristine no flaws.

If its old or used and just needing to better. You probably got to bend . Theres a lot on this . Over at gta i kinda liked nced bender for easy homemade . Or look at other guys ways that work nicely.
