A true Beeman classic, of Santa Rosa vintage. 77K Mk2, original 25mm internals and a tight barrel.

In lieu of the OEM rear micrometer sight I added a Williams FP-AG-TK aperture sight along with a Williams Target Replacement Insert (0.050" inner hole). Original front sight ramp replaced with a Weihrauch globe sight with the lollipop insert.

Tuned for easy and smooth 2 finger cocking using a cut down OEM high power 97 spring. The usual polish where needed, including the underlever sliding tab release. Metal tophat and OEM rear guide with polished washer, piston liner. Once preload was fine tuned, this baby did not dissapoint:

775 fps with JSB 8.4 for 11.20 fpe

800 fps with JSB 7.9 for 11.22 fpe

The easy, lazy cocking effort and gentle firing behavior make this rifle a joy to shoot.

Some pics from a couple months ago when I still had the OEM rear sight on it:

There you have it, my 77k Mk2 Target/Plinker😉. Thanks for looking and hope you enjoyed it.


 
You have great taste sir. Those are the finest spring piston airguns ever made. My absolute favorite. 

I have two San Rafael era guns, one in .22 and one in .177. The .177 is tuned to about 11.5fpe and is a dream to shoot, as I'm sure you know! 

I replaced the sliding catch spring in mine with a much lighter one. Makes it a little easier on the old fingers.

That's a really nice one there, I bet it's an excellent shooter. Thanks for sharing

I was planning on commenting anyway, given the catchy title of this thread as simply a shout out. However your 77 sealed the deal. That’s is exactly the kind of gun that I think of when I think about why I love airguns. Custom tuned, practical, surprisingly powerful, accurate and smooth shooting. I can’t also forget to say a bit of historical value as well. I very rarely like keeping even collector items in stock form when there’s options to “add” value.

They are beautiful!



Wish I could shoot like that.

How are you getting on with the .20 HW77?



I recently picked up a first-gen that was in well-used condition. I'm sure it has been shot off a limb, rocks, car door, etc for many years. I kind of appreciate the patina. I really just picked it up to flip it, but then I shot it, shouldn't have done that... Now I'm in love with it. It even has a fair bit of twang. I should hate it, but it just shoots so well. It is the full-length version, SOOOoo easy to cock, not much more than the weight of your arm. Right at 12 FPE with the brown box Crossman's. It is a fabulous plinker that you can hand to anyone, no fear of scratches, etc.

thumper, thanks man. These old 77's have stood the test of time. They definitely have character compared to the newer 77s. 

Good idea on the spring relacement for the sliding tab release. When I first received this rifle the mechanism was a bit wonky, dry and not smooth to operate. Now its good to go; smooth yet requires a purposeful push with the thumb, with that reassuring "old world" lock up. Yeah, I like the MK2's.

You bring up some good points on the attraction of air rifles, to which I'd add the cost benefit of shooting, especially when you like to shoot A LOT. 

I wouldn't go so far to say that this was "custom tuned" however, maybe just a simple tune or old school tune😉. Work done was simple and straightforward. It's basically in stock form with the exception of an aftermarket piston seal and piston liner, and the original sights can always be easily added to return the rifle to its original state.

The distance from where I was standing to the resettable target was about 16/17 yards.

The .20 cal 77mk2 (an unexpected grail find this year!) is safe and sound. After unboxing I cleaned the barrel, gave it a good wipedown and shot a 5 shot group at 19/20 yards seated using JSB's- didn't even tough the scope settings😉.

Soon I'll install an ARH high power kit.
