HW/Weihrauch HW90 Locking up

[FWB127]

Recently acquired early series HW90! During the cocking cycle when RETURNING barrel into closed position it jams on the return. Check the stock screws, no interference, seems to be the chamber and the bottom of the breach block rubbing and locking up

Anyone else have this occur and know solution please

on mine, if the front trigger guard screw is too tight the cocking arm rubs against the stock. Maybe try loosening that screw a quarter turn?

I was just watching the HFT World’s Day 2 on YouTube and one shooter was using a red dot..On his TX200..

You might check the lockup wedge to make sure it's properly lubed and not dirty or rusted.

Lock up wedge, is the barrel too loose, is the bolt worn?

Really strange one Will attempt to take some pictures over the weekend to show where the rubbing lock up occurs ( 60/70% into the return swing back )

Photo on LHS shows uncocked but the wear marks on the linkage are apparent. THe RHS photo show where the linkage becomes stuck on the tabs . Is it a matter of putting a slight chamfer on the tabs ????? Thanks

First looks like a older gun so maybe look at the cocking arm gliding piece

I love my used HW90 .25. It is an "anti buying more self contained airguns agent", because every time I look at, become fascinated, by air rifles, I say to myself, heck the HW90 CAN DO THAT BETTER LOL.
Did you fix your barrel lock up? If not, you could get it out of the stock first. Then start by checking lock up wedge function. Then adjust barrel free drop as TBT demonstrates for weihrauch springers about 4:48 in at https://airguncalculator.com/
I would not be grinding on OEM parts because many many units are in wild and factory parts has proven to be high quality.

Mine is a 2021 or 2020 product using Weihrauch's serial number driven online database

WDB - DYWP

A user built database with Weihrauch products

www.weihrauch-database.eu

Beyond power adjustability, the trigger, the barrel, the longevity in Weihrauch's line and the many users who have posted online over the last 2 decades, rebuild-ability, ease of disassembly/reassembly, and parts availability, no flyers from my unit [running 19.xx and 20.09grains to start], I 'm sold on it.

I had the same problem on my R-9 ,broken cocking shoe.

Agree 100% Absolutely love my 90 despite have a number of high quality springers ! Think its the lineage to Theoben but really love the fact that its a fully contained gun never needing a spring . Mine is super accurate too and really dont get some of the negative reviews I've seen . The link you provided is a calculator Can you resnd the correct link Many Thanks
