Just bought this closed bolt Mac 10 45 today. It has no safety in a very strange site system. The charging nub acts as the front sight. It is an Ingram Texas gun. Also check out the back of the grip, I've not seen that before. Anybody know anything about this?
What is this?

It’s a Texas M10A1S Lower receiver, the upper has been replaced with what appears to be a masterpiece arms upper (or at least the bolt is MPA), the bolt handle has been custom modified, as well as the sights. Someone cut the original rear sight off the Texas MAC lower receiver and welded on the rear sight that’s on the upper. Is this an open bolt gun?? Looks like the lower receiver was cut open at the rear to accommodate the legs of a stock, but the Texas mac semi auto fire control group does not allow for the legs of a stock to fit in the frame. The upper appears to be an RPB/cobray type upper, missing its front sight, and the barrel has been chopped down shorter, it is not a Texas MAC upper, it has been replaced, this gun is a “bubba” job. The Texas receiver is missing the m1 garand style safety switch inside the trigger guard. This style bolt was sold in both closed bolt and open bolt configurations. This gun would require a welded in sear carriage to function in an open bolt set up without a sear pin hole drilled, mind you this gun should NOT be open bolt and it’s totally illegal if it is… just saying. This Cobray/MAC/RPB style upper should not fit on the Texas semi auto unless it was modified on the bottom to clear the Texas semi auto fire contr mechanism. Could you post a pic of the internals?

The holes on the rear side plates on my Original Powder Springs SMG was for fixation of snaps that the leather shoulder holster connected to. I suspect someone bought an uncompleted TX frame and built the abortion on top of it.
How much for the boot in pic #7 ?
Kinda agree looks like someone smashed it out in their garage.
I swear it looks like a hammer mark just behind the rear sight where they bent the lower over.
Probably where the why the OEM rear sight got chopped off the lower so they could fit a upper onto it.
Probably bent it to far and didn't notice till it was to late.
Cut & reweld or cut and add new rear sight.
Pretty freak'n COOL!!
Kinda has that whole palistinian/kyberpass/pakistan vibe going on with it.
If it shoots I'd leave it as is.
If it doesn't I'd continue to beat on it till it does and leave it just like it is.

Thanks, that's kind of what I was thinking as well. I thought it was neat, and I got it cheap so I have no problems with his condition. As far as the previous commenter, I'm a little surprised that it could have been confused for an open bolt, it's an obvious difference between what's in it and what it would look like if it were open. But that's neither here nor there, I think it is cool as hell. I own several other Mac guns, but they are all open bolt. I just picked this up at the gun show this weekend. I'll put it in the pile with my sawed off model 97 shotgun, my bastardized Norinco Mac 90 converted to under folder, and of course my tech nine. LMAO sad part is, that's not a joke.

But does it shoot? Beaters are always better than safe queens! 👍

That’s not what those holes are for. Those are the stock hardware pinholes, they are for the pin that holds the stock locking hardware into the gun. the desantis mac skatter shoulder holster utilized a replacement stock hardware pin that had snap studs attached to it for use with their holster rig. The semi auto MACs are typically built using SMG frame flats that have the stock hardware pin holes punched, but they remain empty without a pin installed in them as the closed bolt semi auto MACs do not have provisions for a stock

Actually it’s not “obvious” at all. The only thing that’s obvious is that you have NO clue what you are talking about based on that comment alone.
Both the closed bolt and open bolt Ingram guns used the exact same frame and the only visible external indicators of a closed bolt fire control group would be the closed bolt hammer holes and closed bolt safety selector, which are features that the closed bolt texas Ingram M10A1S does not have, since it used an internal fire control group chassis to contain these parts. Therefore the external appearance of the texas semi auto pistol is identical to that of an open bolt semi RPB.
The gun has had stock strut holes poorly cut into the rear of the lower, this is not something that would work with the closed bolt semi auto Texas gun as the fire control group prevents the stock struts from being installed. So if someone cut those holes for the stock struts then they had to have removed the closed bolt internals for the stock to be installed. The texas semi auto is the ONLY closed bolt semi auto MAC that does not have a safety selector switch in front of the trigger pin area or externally visible hammer pins. It also has the original Texas m1 garand style safety removed. The upper receiver is an RPB/Cobray type, indicated by the lack of the visible spot welds on the front trunnion of the OEM Texas upper, this upper would not be capable of being installed in a Semi auto Texas closed bolt lower due to the fire control group chassis in the Texas gun requiring an upper receiver that is clearance cut specifically for the Texas fire control group. That RPB type upper would not fit without some heavy modification, the removed Texas safety and the stock strut holes that are clearly homemade are some very good indicators that the internals of this gun have been modified.
The bolt installed in the gun is a late 90s early 2000s MPA style bolt that was sold in both closed bolt floating firing pin and open bolt fixed firing pin configurations.
From everything I’m seeing, this gun could easily have a sear carriage welded in place for an open bolt fire control group. Not sure what the “obvious” closed bolt features are that you are so confident about, but i know these guns like the back of my hand and the only thing I see that’s “obvious” is that the original Texas M10A1S Internals have been modified at some point in one way or another and that the bolt that’s installed on that gun, even if it is the closed bolt MPA version of the bolt, would never interact properly with the original Texas closed bolt internals. The Texas hammer fired internals are not compatible with the MPA closed bolt hammer fired internals. If it’s still somehow the original Texas closed bolt fire control group, I’ll bet it doesn’t even fire with that bolt.
Go ahead and “throw it in the pile with your sawed off shotgun”
it fits right in with it…

I hate coming off like this guy…. But sometimes I just can’t hold back, it grinds my gears when people are confidently incorrect 😅
I’m genuinely happy you have the knowledge base that you do. Since the transferable MG world is frozen in time, it’s losing that knowledge about old designs slowly by the day. I hope to pass my guns down to my kids someday, but by then a lot of what is known will probably just be discussing same information in the same books over and over. A lot of the unwritten and hands-on knowledge probably won’t exist anymore.
