I found a couple of problems that I had to address with the dremel.
First: The bolt catch/release ear caught the rear of the adapter and then jammed against the back. I ground out quite a bit of the rear of the magblock and ramped the top of it. Now the bolt catch moves and functions just fine. Second: I ramped the top of the rear of the magblock. I found that it was difficult to use the charging handle to move the bolt. Used some spray powder marking paste over the mag adaptor and found where the bolt was dragging/hitting. Same for the bolt release ear. Grind, grind, grind until no more interference. Third: I beveled both sides just a hair at the top. I found that my upper has a slight bevel where the mag adapter fits against it. This was one of the things that was forcing me to open the upper/lower assembly to insert properly. Again, marking powder worked really well for this. Now, I can insert the adapter without opening the gun. The mag release button will fit flush when it is in place and release it. There is no drag when charging the bolt and the Texaco mags (stars) fit well. I hand cycled 20 rounds and everything went well. Now, if I can just get out to the range and try this...... BTW, this is in an OLY lower/Colt upper. Dave |

I did a few of SBR7_11 fixes and they seemed to be just what the Doctor ordered...
I removed the block's mag catch and filed down the half-round pad that is machined or cast into the back of the catch, now my mags stay put. If I pull to beat all hell I can still get my IMI mags out, but who the heck would do that when shooting. My south African mags wouldn't come out if you used a truck. I also "squared" of the inside back radius area and a few more of my mags now actually fit. This block will be the cat's meow once we make a few needed small changes. Hey, it's actually kind of fun to play around with it a little. You also get a feeling of achievement. |
|
|
Ohhhhh....opps. Well, evidently by doing what I did achieved the same results. The "Tooth" on the mag catch goes into the mag deeper and it holds the mag in. It works real good with unloaded and loaded mags.
I was a little unclear about the "pad" you refered to, but this worked good....Damn, I looked really stupid for a minute...yes, only for a minute;) |

[red]Well after a few hundred rounds through my mag block it was starting to release from the host gun when I would inadvertantly hit the standard M-16 mag catch button. Since my finger would reach for the standard button by simple memory reflex, I could see that it was going to be a problem for me.[/red]
[purple]NOTE: This fix is impractical unless you are dedicating a lower to the 9mm conversion since the standard mag release button becomes almost inoperable for regular use.[/purple] [blue]The fix:[/blue] I removed the standard M-16 mag release button, spring and catch. I then used a cutoff wheel on my Dremel to cut the last four threads off of the catch. After touching up the cut with a stone and B'wood Casey touch up marker I reassembled the mag release. By rotating (screwing in) the catch as far as it would go the button ended up flush with the side of the receiver and does not lend itself well to being pushed in by finger. To insert the mag block, push the M-16 mag release button all the way in with a derylin take down pin tool or similar tool until the mag block inserts all the way in and then release the mag release. The M-16 mag release button should be flush with the side of the receiver. If it is not, screw/unscrew the catch as needed. It is a simple and easy fix to a very real problem and the end result looks slick. I scanned a pic (below) of the results. Sorry it isn't a closer shot.

OK, got mine to the range today after the repairs noted in earlier post.
Mag block fit in fine. Nice and tight. Used only the texaco(Star) IMI mags to test. Ran about 40 rounds semi auto. Everything went nicely. Ran about 200 full auto and everything went well also. I had one mag that seemed to pop loose and thru things into a spin for a minute, but checking the catch and insuring everything stayed tight took care of the problem. Ran a couple of 25 round bursts and everything ran nicely. Might have to try the mag catch adaptation that SBR7_11 discussed in the earlier post. BTW. Ran S&B thru most of the time. Tried the Radway Green also. I really like that way that stuff goes! It is hot. Dave |

I was going to do some work on the mag catch button on the mag block adapter and put on a raised button of some sort to make it easier to find and push.
In the meantime I stuck a piece of rubberized, textured pool tape on it. It worked so well that I am going to keep it like this until, and if, it proves to be inadequet or VM Hi Tech comes out with an improved version. Mario |

Hey Mario!
John called me at home the other night, Monday I think it was, around 9:30pm EST. He asked for me by name, and wanted to know if I was still interested in a block. I told him I had mine already, and Lane had got it for me,, he remembered Lane. Asked if all was ok, and said he had been following AR15.com thread about the adapter. I felt funny owning up to this thread, told him I authored it and described the minor issues I had to correct, he seemed really interested to improve upon the product. I did mention the backwards mag release, he siad they are going to address putting some kind of pad or something to fatten the release paddle,,, I told him I was just going to install an extended 1911 style mag release button, he said the release' paddle should be drillable. I told him mine works as intended, and that the ejector was right on the money when the block installed. |
|
|
Yeah, he called me too. Not long after I got my block... probably August 5 or so.
I told him of my impressions and some thoughts that I had and he seemed receptive to them. I told him about the threads over here and he said that he had been reading them with interest. I have a feeling that there will be a Model 2 in the works by about this time next year. Take care, Mario FAMO, Inc. |

You guys keep comming up with some cool solutions... I need to read this again with my 9mm parts tonight but I am still trying to appreciate...

I sent my money off today for a VM magwell adapter after talking to John at VM Hytech. He says the models available now have a larger magazine well and raised button. As soon as I get I will post pics for you all.

Offspring,
Did John mention if the new raised button is interchangable with the old one? Mario |
|
|
I didn't ask and he didn't say. Sorry.

any updates on these blocks? Did VM fix these little issues?

I just got my VM Mag block. It was tight as hell in my Bushmaster lower, but I think it is "permantently" in there now. I can't press the mag release and pull it out. The mag release button is raised, I have some cheap uzi mag I got off Cheaper Than Dirt and it slides in fine and the mag catch holds it in place with a firm thump on the on the bottom of the mag to seat it. Below are some pics.
edited to add: I haven't shot it yet. Will do that next weekend. I hand cycled 5 snap caps repeatedly with a couple FTE. That could have been user error. Also the mag release doesn't look that ugly to the naked eye. I guess the camera brings the worst out. I think I am going to sand that a bit.

Offspring,
Looks good. My mag block fit real tight in my BFI to begin with and then after a while was removeable by hitting the standard mag release. That's what prompted me to disable the mag release button (see post above). I tried to contact John at VM Hytech a couple of times and have gotton no reply. I guess that I'll have to live with the textured tape on my button for now... I really like the looks of the beveled mag opening, is it as funneled as it looks? Mario |
|
|
They were closed for 2 weeks during Christmas. He was quick to respond to phone messages. I just pryed my mag block out. It slides right into my Colt. Think I will do some sanding later.
|

Thanks, I'll give him a call Monday.

No FTEs or FTFs today while shooting, must have been user error when hand cycling.

ilikelegs-
No, I got distracted in the meantime and never called. I'll write the number down again and try to do it Monday. The magwell works great for me without any modifications at all so the retro fit on the button isn't a big thing. The disabling that I did of the button on the lower and the texture tape on the VM HyTech button have worked for me re: finding the mag release. I guess the big thing that helped me the most was that I was ready to buy bulk mags for my UZI when I got the VM HyTech block. I tested a bunch of different mags in it that came with, and already worked in, my UZI and then bought in bulk the one that worked the best in both magwells. I've got two dozen of all the same 32 round mags now that work in both guns. Mario |

HEY! WAKE UP!
John over at VM HyTech got in touch with me today and is sending me a raised button mag release for my first generation mag well block. He said that it will drop right in. He told me to post over here for any of you guys that bought the first generation blocks to contact him if you want the retro-fit raised button release. The best part? IT'S FREE!

Now things are starting to get interesting. I've been thinking about replacing my HK-94 with a 9mm AR. This could be the ticket.

Thanks to John at VM HyTech! |

I have been holding off buying one of these until it took all Uzi magazines and the magazine release was fixed.
Does the current version of this adapter come with the raised magazine release and already milled to accept all factory Uzi magazines? |
|
|
Deanh-
Get in touch with Offspring who posted at the top of page two, he seems to be in possession of a new version. Mario |
|

I just bought two, one for me and one for another board member.
It had the raised knob, and works well. Mine didn't like the imi 25 round mags. A little touch up with a metal file fixed that. Now it works well. The other person's block was a much better first fit than mine. He will likely need to file a little, but not near as much as mine. |

Good news with my mag block. The 9mm is finally
a reliable gun. A few of the brand new mags are a tight fit and they will not stay latched in the mag block if they are fully loaded. I think filing the notch where it catches the release will work enough. My old beater Uzi mags work the best. I have shot over 500 rounds with the new block and most of those rounds were bump fired. I'm very happy with the Hy-Tech block. |

Has anyone ordered the block from Brownells recently, and was it the "2nd version" with the raised mag release button?

I just got two new VM blocks for use on my guns, it appears they are made to only work with rounded magazines.
Well the mags I have are square, and I don't particularly like the idea of it not being able to use ANY uzi mag, just specific ones. So I spent over 3 hours yesterday using files to square up all the inside edges of the magazine well, test my magazines for fit as I went a long. I got the one so all my mags slide in easy and drop free. I'm going to finish off the job with some emery cloth on the inside of the mag well to polish everything out. I may or may not have it reanodized, I'm not sure that it's particularly important. On a positive note, the mag blocks did fit in the mag wells on my CAV-15 lowers without any modifications to the lower or the outside of the mag block. |

I went shooting this weekend with the 9mm
and the feed ramp on the mag block broke. So I will be seeing about getting this replaced. |

I have 5 of the painted south african contract 25 rd mags from Vector, and they all have square backs. It took me about an hour with the file remove the radii on the rear corners. Now all my mags go in. They don't drop free, but I don't know if they are supposed to. I realize it takes extra machining steps to square off the rear corners, but it would make life a lot easier for all of us with square-backed mags. Since the corners don't take a lot of wear, I don't think I'm going to bother with re-anodizing. Other than the fact that none of my mags would fit, it's a nice piece of kit. [;)] It fits nice & tight in my magwell, and it has the raised mag release. I did a variation of Mario's fix for not ejecting the block (although mine doesn't fall when I hit the AR mag release). I screwed the mag catch in all the way, which leaves a few mm of screw sticking out of the middle of the mag release. It is a reminder when I go to hit the AR mag release, because I feel the sharper end of the screw instead of the flat button. |

I'm thinking about drilling through mine and putting a couple 5/64th roll pins through the block and receiver to make sure I don't release it by accident.

The magblock I got from Brownells wont take the square mags; they wont even start in the magwell.
I have emailed HyTech. I also have a problem with all the Uzi mags. The cartridge cases sit too low in the mags. The lips hold the cartridges down so that don't come up all the way in the back. Causes the bolt to override them instead of stripping them from the mag. Tried to bend one of the IMI lips and it began to crack. Too brittle I guess. Did anyone else have this problem? |
