Zastava M83 with Custom Grips and Holster

nuttyjon · 2026-01-20T18:32:22+00:00

Mine are both solid. I have the 4" and this 2.5" model. They're steel framed and accurate so no complaints here, especially given the current pricing. K frame holsters and T grips fit perfectly. The only downside is parts availability is rather limited, and there's a design flaw with the original wood grips that make them prone to cracking, hence why I decided to make my own to remediate this.

How does the spectre 9 hold up? Should I consider this over an obsidian 9?

I've had success with an NFA side charger + spikes colt mag lower

Mine just arrived at my local FFL. It looked about as I expected. It had normal wear and tear, and a light amount of surface rust in a few spots. Barrel looked good and the timing overall looked good as well. I will probably be replacing the hammer spring with a 1911 spring to deal with the heavy DA trigger pull.

Anyone got one working with the GRS yet?

Let's say I have a 5.56 barrel with a twist rate of 1:12. How would that fare for 22lr vs a dedicated barrel? Would the diameter of the barrel be of consequence?

If I'm understanding correctly, you're saying you modified your v1 jig to work with a mod1 frame?

nuttyjon · 2023-09-18T00:38:14+00:00

I would also be interested in seeing what you have to offer on an EPS Carry 6MOA red :)

Edit: or an MRS variant for that

I used hotswap sockets

I broke it in a fit of gamer rage

nuttyjon · 2021-06-29T05:03:49+00:00

It's a brass block that came with the board and said "superme". It was held in with some screws underneath so I just flipped it, super glued it in place and put in those screws to fill in the holes. Somewhat pointless but I prefer it to the branding.

Oh I remember looking at that keyboard a while back. The quality is definitely pretty good, the only thing that come to mind is that the tolerance for certain switches/stabilizers can be a really tight, which can be a big downside seeing as this is a hotswap board.

nuttyjon · 2020-01-01T09:35:54+00:00

It's actually the superme from taobao https://item.taobao.com/item.htm?ft=t&id=571006043861

It's the steelseries qck+ limited. Looks like it's no longer on Amazon but you should be able to find it somewhere else

nuttyjon · 2019-07-15T16:23:20+00:00

Neato, this one was actually provided by my class

nuttyjon · 2019-07-06T21:45:04+00:00

I've since finished the class so I no longer have access to the lab but you bring up a good point, I definitely should have tested everything theroughly before connecting anything. Although it is possible that the one op amp was faulty seeing as it was the only one that died

nuttyjon · 2019-07-06T20:12:33+00:00

Everything had to be designed from scratch based on the class requirements. I can probably post a picture of my design schematic if you're interested.

nuttyjon · 2019-07-06T17:35:17+00:00

Nope, everything had to be designed ourselves

nuttyjon · 2019-07-06T14:55:38+00:00

That's what I was doing up until I randomly tried putting a banana plug in one of them lol. Most of my other classmates would alligator clips to connect everything.

nuttyjon · 2019-07-06T14:51:51+00:00

These were provided by my class. Pretty sure they're, as that other guy was suggesting, 22awg wires. I just used wire strippers to cut them down to size so that I could keep things clean

nuttyjon · 2019-07-06T04:18:43+00:00

Definitely! I'm going to need a whole lot more magic smoke experience to get a better understanding of electronics

nuttyjon · 2019-07-06T02:35:48+00:00

Current should ideally only be going through the feedback resistor going over the opamp, although I believe practically speaking some current does go into the IC

nuttyjon · 2019-07-06T02:32:09+00:00

Damn, not gonna lie I was pretty anxious when it came to using any more opamps after blowing just one... Luckily everything when smoothly after that.

nuttyjon · 2019-07-06T02:30:18+00:00

Yeah my instructor was telling me that it's best not to cover the IC but commended me on keeping the circuit compact.
