I also have a top loading Hahn block originally on my RRA A4 16" CAR and no problems with a couple of Colt mags that I have.
I'm currently waiting to get more of the new C Products stainless 9mm mags but since they're delayed I went ahead and got a VM Hy-Tech mag block so I could use my IMI Uzi, generic Mec-Gar Uzi and other off brand mags. The Hy-Tech mag blocks fits fine on my RRA 9mm marked lower no problem same as my original Hahn block. The only slight problem with the Hy-Tech is they don't fit some of my off brand Uzi mags that have large radius corners of the mag catch holes. I have to file the mag catch holes and make the corners into sharp corners and then they work fine. |

My 2 month old VM-Hytech block needed about 15 minutes with a file to allow all my Uzi mags (except a cheap Argentinian 40 rounder) to work.
Just lightly file the rear of the block until the mags slide in easily, it only takes a few thousandths of an inch to do the job. It was worth it to me. |

That's all I use, no fuss, no muss.... I've had Uzi since 1988, so why do I need to worry about bells & whistles of CLOT operating system ?

The main thing I'm concerned with is the magazines fitting in the block. Before I got the Hahn blocks I tried three different ASA blocks and none of them would consistantly accept magazines. The magazines, Colt and modified Uzi, would bind in the ASA blocks about 50% of the time, even after I did some filing. The Hahn blocks readily accept all magazines. I'm just worried I'm going to have the same binding problem with the Hy-tech block, especially after reading the tacked thread. |

A few minutes with a file and you don't have to worry about binding.
I've seen more people screw up the magazine conversion cuts for the Colt system than I have filing out a VM block. |

I got mine from Brownells about a year ago and it worked fine with no modification to the block or my mags. It is in a Stag lower. I may be just lucky?

i bought one a few months ago, uzi mags are cheap, and i use it on my SBR that i switch between .223 and 9mm, so i needed quick change mag block. BUT i had to gring a line down that back of my mags for them to work well, and they don't release fast, so you can't do quick mag changes. But i like everything else about it.

I had one of the early models..did the mods to it. It was fine, but when I sold the 9mm setup the block went with it. I have built 2 more since then......went with the top loading Hahn block. I don't have an Uzi anymore.
My point is since I have no Uzi or Uzi mags...the Hahn block is number one for me. It seems like it adds some unneeded bulk and weight......just my $0.02 |

I love mine, it's a newer one and I've never had a problem with it accepting any mag I've used, both with the flat and seamed back mags.

Thanks for all of the responses
 Is Brownell's the only place that sells the VM block?

Brownells has them in stock @ 149.95
VM TECH is making a run of them now, they will be availible in 2 weeks. They said it is the same price as Brownells. I just bit the bullet and ordered the adaptor from Brownells. |

Get it and don't look back . . . especially if you have that many Uzi mags already.
I love mine and would recommend it to anyone. I do have a couple of mags that won't work with mine but only a couple. |

That is exactly the rifle i want to build. What sights are those? I want to go for the MP-5 sight look, and that TROS barrel. |

This is the route I took. Made it simple as I have an UZI with plenty of unmodified mags.
I did a little hand filing so that all my IMI 25 & 32 rounders would work in the VM Hy-Tech. |
