If someone is hardup for a mag block with the boolt stop feature, Garrison Mfg was making them, at least sometime in the recent past. The only downside is that you have to use their dedicated bolt catch in place of the normal one which means no conversion to 5.56, at least not at the range.

Sadly I have a VMHytech block, Uzi mags, but no 9mm upper! :(

40 rounders

Does the VMhytech work with the 40 round Vector mags or is a maybe kind of thing?

Anybody try the new Promag?...Yes

O.K.....got my 2 mags yesterday.

Very first impression......cheap crap.

After I settled down a bit and checked them out more in depth....They aren't metal lined like I stated earlier, you can squeeze the sides and they flex in and out. The follower is also plastic and kinda pops out of the mag tube a bit too far (like the real crappy Pro-mag glock mags) amd if you really tried, it seems like you could pull the damn thing out. The floor plates seemed to stay in place pretty good while just doing normal things like loading and handleing.

The good part is they loaded easy and actually held a full 32 rounds. The outside dimension at the top taken from left to right bulged from .860 to .885 when loaded. I empted the mags by hand with a pen and every now and then 2 rounds would fly out when only pushing one.

My ASA mag block in on the way, so I didn't get to check out how they fit in the gun.

If they work perfect........even though they seem flimsy.....I would probably buy a few more. If they are 98%........no way.

When I saw the picture for the first time, Styer SPP/UMP mags came to mind.....not even close to the same quality.

I think everyone interested should just get ONE first.....then order more if you are satisfied.

I ordered 2 of the new Pro-mags today....should have them this week. They are NOT metal lined. That would've been better, but if it's good polymere...should still be o.k.

2 delivered for $58....should be cheaper, but had to check them out.

As has been pointed out, Pro-Mag is making 32 rnd 9mm Colt mags in polymer ($28 retail, mfr part COL-A3).

I have it from a good source that there were problems with the first batch - lips sat a bit too high causing problems on F/A. They worked fine shooting S/A. If you see some that are unreasonably cheap, they may be early run mags.

The newer ones work fine, I have personally observed them in full auto action on a friend's gun.
How did they work out?

Mine are the newer ones and they work great...I don't have hold open, so can't say how that works. Haven't shot a ton yet, but both have funstioned perfect for 150 plus rounds each.

I took my new 9mm AR to the range today and shot it for the first time... 200 rounds of Winchester white box without a burp of any kind :D

I'm using a RRA upper on a RRA lower, with the RRA 9mm hammer and buffer, and a VM Hytek mag block.

Right now I only have one Uzi mag (the one that came with my Vector) and it's a Lyttleton South African model.

The RRA fit and finish are really nice, and the weapon functioned flawlessly, so I have to give this combination the big thumbs up.

I have as American Spririt drop-in-from-the-top magwell block still in the wrapper, and will try it out once I get some IMI mags in and modified by Joeblack. FedEx has apparently lost my order of stuff from DSA so I'll have to report on that combination later...

Pics of the carbine with a sexy chick and all that are about a week away...

I have a photo shoot scheduled for the end of next week, weather permitting, and we're planning to do a bunch of cool gun pics with the Uzi, AR, etc.

No, it's not Avatar Girl, but a real cutie, none the less.

I have this idea for a really cool shot that I'm trying to figure out how to arrange... The bikini-clad model draped over a mini-gun, sitting on the bow of a big-ass Scarab-type "cigarette" boat.

I thought about one of the new AirSoft mini-guns the guys here in Texas are making, and I can probably convince a guy with a cool boat to go for that in exchange for some prints...

This is the kind of demented stuff photographers dream up in the "down time"...

And I promise, pics to come!!!:D
