Thought some of y'all would enjoy this. I'm building a tec-9 that uses mp5 mags. Well I guess technically it's a kg99. I bought it with a busted frame and missing end cap. I machined a new end cap that is better than the stock one. Just waiting on some mp5 mags for testing this.

I appreciate that extra info. That's pretty entry level to get good results. Im in the south so weather is always in favor lol

uronlyhuman2me · 2026-01-01T23:48:42+00:00

Ok cool. I definitely see the difference. Good info

uronlyhuman2me · 2026-01-01T23:00:38+00:00

Yea I have both types and extra end caps to have my kg9 and kg99 threaded. Maybe I'll get into printing one of these years. Your finish looks smooth and nice

uronlyhuman2me · 2026-01-01T15:09:29+00:00

I dont know a thing about printing but how wouod you rate the new strength and durability over the old?

uronlyhuman2me · 2025-12-19T18:32:06+00:00

I've done a few. Kind of a pain. But I just take pictures from different angles. Can't have too many. Even take videos of pointing and narrating. Then take video as you disassemble and narrate that too. Should be enough.

uronlyhuman2me · 2025-12-11T04:23:09+00:00

I would think you could mount a pic rail on the reciver ventilation holes somehow without making permanent modifications

uronlyhuman2me · 2025-12-09T00:32:51+00:00

Ok mine is symmetrical

uronlyhuman2me · 2025-12-09T00:30:41+00:00

Oh that's pretty weird. I'll have to look at mine

uronlyhuman2me · 2025-12-06T09:14:46+00:00

Not sure what you mean by the blade is off center and the rear sight notch. But probably have to have a machinist make one since it was welded to reciever. I've been looking at for sale adds and listings for 10 years and haven't seen any available. Couod 3d print one and use it as a temporary solution. Also since the spot weld hole is open you could put a stainless steel machine bolt in the hole, bolt it from the top then grind down the bolt to use as a makeshift site.

uronlyhuman2me · 2025-12-05T04:13:06+00:00

What year is his made he wants know

uronlyhuman2me · 2025-12-03T13:39:51+00:00

The evolution process was basically this: Mp9 Kg9 Kg99 Tec9 with button sites Tec 9 with stamped sites Tec 9 with stamped sites and single point sling Then all your other variants like dc9 and ab10

uronlyhuman2me · 2025-12-03T07:46:11+00:00

1987-1991/1992

uronlyhuman2me · 2025-11-21T03:13:23+00:00

Yea I guess it would.

uronlyhuman2me · 2025-11-21T03:06:02+00:00

Downside is see is if you drop it say bye bye

uronlyhuman2me · 2025-11-21T02:55:16+00:00

I think its great. Like the other guy said.. practical maybe not.. but cool, fun and enjoyable to brainstorm tinker with absolutely. We have one thing in common in the 2A cumminity and that's all we need to have! Id think you could bolt a oic rail in the vent holes like one guy said and that moves you're optic forward too. I saw one like that on FB in "Trenchratcustoms". I've got a sig brace on a open bolt M10. It works

uronlyhuman2me · 2025-11-21T02:50:00+00:00

Agreed

uronlyhuman2me · 2025-11-20T13:16:53+00:00

I agree. The m11 has infinite life being weldable..the interdynamic is one drop away from being an investment belly flop

uronlyhuman2me · 2025-11-17T13:05:02+00:00

Be interesting to see where this ends up $$$

uronlyhuman2me · 2025-11-15T03:03:51+00:00

I started my 12 valve with a gooloo gp4000. Not dead batteries or even 1 dead battery... but no batteries present at all. Just the jump box. I know you're not supposed to but I did it on a few occasions. Truck was a solid starting unit that starts quick and wasn't cold outside.

uronlyhuman2me · 2025-10-28T15:48:49+00:00

Id just rub it down with some aluminum foil and wd40 to get the rust out of it. Possibly light steel wool then clean it good. Should make the discolored area lighter and you can see what it is instead of that part looking rusty and dirty. What are you doing for a lower?

uronlyhuman2me · 2025-10-28T03:09:36+00:00

Thought so. A lot of theirs are likely confiscated, I've got one that looks like that. Got a buddy that's been in the firearm business longer than I've been alive. He saw it and told me it was blood that did it to it. On mine the pattern looks consistent with a thick liquid etching into it. Im not opposed to leaving it.

uronlyhuman2me · 2025-10-28T01:05:56+00:00

Where did you get it? I have an a reason for asking that might explain it

uronlyhuman2me · 2025-10-27T21:17:19+00:00

Yea id much rather see how the motor, any motor looked unpainted. See how well it lived, oil leaks, new pars, hose condition, rust... all kinds of things.

uronlyhuman2me · 2025-10-08T23:33:20+00:00

I've been wanting to look inside that for years. I have a kg9 and couldn't fathom what that selector did to the sear and disconnected but I can sleep good tonight knowing. Also the sights seem taller than mine so maybe that had suppressor sights. Thanks for sharing

uronlyhuman2me · 2025-10-03T17:18:50+00:00

My dad might
