Hello all, new to the forum (but not to AR's), and I am seriously considering a 9mm AR. I already have a lower, just deciding on what upper to get at the moment (11.5 + 5.5 is tops at the moment).

So to the question... are the inexpensive pro-mags reliable in your setup? I have heard many good things about them (not typical of pro-mag) and couldnt pass on the 10.99 price at Natchez, so I bought a few. Please tell me what block you are using as well.

Maybe to keep things simple, do something like "Type of Block/Whether Pro-mags are reliable or not" Feel free to elaborate on that as much as you want.

Thanks all.

Tried a couple over the years, gave up on them. Quality may or may not have improved, but it's not worth my time or money to find out.

Hahn top loading block - Promags = utterly useless

RRA bottom loading block - I had 2 promags, 1 worked okay, the other didn't work at all. For the one mag that did work, I had to use JB weld to adjust the follower so that the bolt hold open would work.

I threw away my promags, sold or gave away my uzi mags, and now I only use colt mags. They are expensive, but worth it in my opinion.

My 2 cents. I am using the Garrison Manufacturing Inc. setup on a RR OLY lower. I have 11 promags and they all work perfect. I noticed that out of the 11 mags that I have there are three different generations(slight differences). But I have not had one minutes problem with any of them. I shoot in a subgun match and I have seen several other people with these mags and they could not get them to work well with there magblocks.

I have a Hahn top loader. I bought 6 of the Natchez ProMags as who can resist the price? I was lucky to get a single round to feed. I broke out the dremel and recontoured the feedlip area on one and it runs about 80%. I've done a little more shaping but haven't been back to the range to see if it helped.

I was kind of wondering about the Glock 21 Pro-mags that are 45acp and 40rd drum type?

the promags work great in a RRA

I hope so, but I'm still waiting. Hurry up RRA.

RRA block and ProMags, flawless performance once I adjusted my magazine block.

Thanks for all the replies so far... since I have a RRA lower and plan on a RRA upper, maybe I'll just go with the RRA magblock.

To all those using the RRA block, are you using the "old" style, or the new (supposedly inferior) style? If you are using the old one, is there a place that the old style is still available? Doing all this research has somewhat racked my brain... I seem to recall that RRA has gone back to the old design, but I haven't been able to back that up with posts from the forum.

Again, thanks for the replies so far, and keep them coming... I think with the pro-mags being such an inexpensive option to the colt mags, this thread may intrigue other potential buyers.

RRA bottom loading block......I have had great luck with the promags...all work great and activate the BHO every time. I have had more trouble with the mag block moving then the promags. I have recently "FIXED" the block in place with a small screw through the front of the lower near the pivot pin. I could give a shit if I lowered the value on the $100 lower.....I would rather have it stay in place 100% of the time......It is a dedicated 9mm, so I don't plan to swith it around.
