Topic: HK model HK269 40mm grenade launcher diagram

[Rob Caunt]

...or any of the HK 40mm hand-held system, aka the AG36, GLM, or HK169.
Does anyone have available to share a copy of, or link to, a technical drawing, exploded diagram, or (best) an armorer's manual for the above launcher?Anything beyond what is available on the HK website is appreciated, particularly some kind of spec on factory trigger pull weight.
Thanks in advance,
Rob

No clue if you'd care, but HKPro site has a thread about the armorer's course. Maybe some user can source the document you need, if all else fails.
Good luck!

Thanks Nathan, that's more than I had to work from.  Some good photos in the link.

The US Army Grenadier Guide (GTA 07-01-006), lists the trigger pull weight of the M320 as 11.25-15.75 lbs.  The M320 is the US Army version/designation for the H&K AG36.  I've used one a number of times and they are quite fun to shoot.

Hi Rob
I do have a "very old" H&K document that has information about the older version called HK 69, albeit no trigger pull data.
I can scan it and email it to you if it will be of any help.
