Steyr Hunting 5A - What does this screw adjust?

RockBall · Aug 1, 2017

In the picture, the red arrow is pointing to a screw that was not tight when I turned it with an Allen key. I presume it may be used for making some kind of adjustment since it wasn't tightened down, but I do not know. I will appreciate a response if you know what this is for. I'm also looking for documentation on how to make adjustments on a Steyr Hunting 5 Automatic. I have had a hard time finding much information on it.

Thanks.

Have you tried asking Styer? They're usually pretty fast at responding

To fine tune the clearance of the barrel to mag contact, after the clearance it set tighten the other barrel screw.

you need just enough clearance so the mag cycles in and out without jamming and will give you less air blow by to help lower your ES.

I sent them an email after seeing your post. So far, no response.

Weird, they must be on "summer break". The few times I sent them inquiry, I always got a response within a few days.

Maybe try the online form

UPDATE: I received a response from the Chief of Technical Service at Steyr on August 18th with very helpful information. He said "Don't touch this screw," and included information about what the screw was for.

Thanks akshonc for the offer. I sent you a PM.

@RockBall can you please send me the information you got about the screw.

I know what it is. It is the set screw that holds the choke in. The 40J versions do not have a choke under there, but the 24J and 16J versions do. Here is a flyer I was sent from Steyr on the subject.

@mmahoney Thanks for the information.

RockBall · Jul 28, 2018

I haven't logged in for a while so I just saw these recent posts. The link from @mmahoney to a PDF is the same PDF I received.

I didn't have a choke in my gun. I used Blue Loctite on the screw to keep it positioned near the top since I have no need to mess with it. Afterwards, the problem I was having with inaccuracy of the 5th shot seemed to have gone away about 80% of the time. This could have been just a coincidence but I'm happy my gun is performing better.

Hi Rockball,

I too was having inconsistency with my fifth shot. Penchetta told me that it is because the magazine and barrel lose alignment. Sure enough I reset the magazine to the barrel and the 5th shot stayed consistent. I put Loctite on the magazine set screw to keep it adjusted. Otherwise, it tended to wiggle loose after a few magazines.
