I see that there are two hahn mag blocks - one that inserts from the top (and doesn't do bolt-hold-open) and one that inserts from the bottom (and does the bolt-hold-open thing with colt mags). Any other differences between these two mags? I'm a little curious about what the "top loading" mag block has to offer - there must be something to it, otherwise they would just make the bottom loader.

I keep hearing about Hahn mag blocks, yet no one posts a link to a site that sells them. Google doesn't bring anything up. If anyone replies to this thread and you know where to get one, POST A LINK PLEASE!!! (sorry to jump in your thread)

I believe our own TREETOP/Adrenaline Arms has them available.

If he doesn't have them, check at Brownells

The quality is untouchable and the price is right.

I have the bottom loader since I use colt mags and I love the block. I personally think its the best on the market. I had a Tacblock which is a crossfire clone. The Hahn block has a nice way of keeping the block from falling out. It has a wide roller that is pushed forward by a set screw. BOTH bottom and top loaders have this feature.
Also the OLDER bottom loaders had a small spring loaded detent that would protrude out from the top to additionally keep the block from faling out which I thought was really cool but they killed that feature. I called and was told that people were breaking that part.
So now all the current production bottom loaders only have the roller to keep them from falling out.
The TOP loaders, in addition to having the roller, also have a little ledge that keeps it from falling out. It rests on I think the right side fo the bolt release.
Also the Hahn blocks have nice machined in feed ramps on their blocks.

Brownells is one source that has the Hahn blocks:

Oh well, I always figure that Brownells is overpriced, but it sucks to be reminded of it after you just placed an order.
