most difficult gun to reassemble

[Battis]

This gun, a Savage and North .36, looks complicated but it was relatively easy to reassemble. Not the Nylon 66.

H&R revolvers. Elmer Keith christened them 'gunsmith's nightmares' and recommended returning them to the factory for repair. Unfortunately no longer possible. After my gunsmith tried (and succeeded) in working on my 999 he put up a sign saying no more work on H&R revolvers! He stated that in repairing mine he broke two other parts.

MK3 22/45 was the roughest for me.

My Ortgies pistol gave me fits until I learned the secret tricks.

My Ortgies pistol is what got me thinking about this.

I've not had the pleasure of working on a Nylon 66, and I also found the Ortgies and H&R revolvers to be "interesting", but I think the Winchester 97, the shotgun with 97 moving parts, was my biggest challenge. Some semi-autos ( pistols, rifles and shotguns) are tough because of very strong springs are difficult to reassemble unless you come up with a way to hold all the parts in place while pushing with all your might, but not so much because of complexity.

If it wasn't for youtube, this gun would be quite the challenge. Once you learn which parts need to go back in first and held with the pin, it's not so bad.

Honestly one of my least favorite guns to work on that I currently own is my GP100, which is also my favorite revolver. Specifically, I hate trying to fight the cylinder off the crane. The best I've found is to soak it in Hoppes for a while to soften it up, then slip a long T handle allen between the crane and cylinder. This gives you something to pull on. Then you pull, twist, PULL, twist and pop it comes out right when you least expect it. I don't understand why Ruger couldn't have made the GP100 like the SP101, which is far easier to remove the cylinder.

I've not disassembled a nylon 66 further than the receiver cover.

I'd say the hardest I've ever done was an NAA mini revolver.

I've disassembled several Ruger 22autos. I owned a 22/45 for several years. As a result, I can disassemble it and reassemble it blindfolded.

I've heard the BAR/FNAR are really difficult to take apart and the manual says you should only ever perform a basic field strip.

I've never had one to play with, I have had an Auto-5 apart and while it was easily the most complex rifle/shotgun i've serviced (I've heard JMB never used a single part when he could use two ), I also didn't find it all that bad.
However I live in the modern era and I had a couple videos and guides to help me along, without those it probably would have taken me much longer.

remington 552 speedmaster 22 auto for me, If you had 7 fingers on each hand it would cut a days worth of time off reassembly.

I have both a Nylon 66 and a Ruger MarkII. One time I started to slide the receiver cover off the 66. Saw all those parts and slid the cover right back on. The Ruger got me and after a good cleaning I fought that monster for a 1/2 hour. I then inlisted the talents of my wife and it only took another hour and it was a good as new! Never again on either one.

Nylon 66 is tough - but I think Ruger standard and Browning A5 are just as tough .

This ^^^^- and the Remington m8/81 IME. The last 66 stock that a neighbor broke; Remington just sent a "black diamond" stock- that's all they had left. That was the second one I'd done and I cussed just as much as the first one.

I've never owned a nylon 66 and never had anyone elses apart.
I did have a SVT-40, I don't recall it being difficult, but I remember there were lots and lots of parts involved.

The one I've had trouble with is the Colt Woodsman, I had a series two apart once, and had to bring it to a gunsmith to get it back together, he showed me the 'trick', which I have long forgot.

I agree with the Colt Woodsman. A fellow worker brought one to me one day in a bag and asked if I could reassemble it. I did it with difficulty. When I gave it to him the next day I warned , don't ever press that button on the top of the slide again.

Unless my Ruger Mk III starts oozing crud, I'll never break it down again! Thankfully, I don't shoot it much.

Have one in a box in the basement right now. Got most of it could not get the spring down the side of the hammer . Sometimes it is better to just walk away for awhile.
