These ProMag magazines at first I was skeptical because of the low price bit I'm impressed I ran through these mags with 100 rounds no issues

dont buy
i bought 10 of these. The magazine works for about the first 20 rounds. Then will jam every round. i think the spring is weak. i put a piece of wood in the magazine to shim it up to a 21 round mag and it works fine that way. would not recommend. I much prefer the 25 round Magpuls, they actually function as designed and fit in your pocket better.i also have a 32 round promag for my sr9c and it works fine. so i cant say all promag stuff is trash.

Surprisingly easy to load
I ordered 2 but have'nt had a chance to fire them yet but they are surprisingly east to load. Hand loaded 40. Easier than hand loading 30 -556. maybe because I could actually get 42 in the magazine. I am happy with them.

Pure Awesomeness!
I ordered 4. Mfg. Dates on 2-2016-11 & 2-2017-03 on the other. I built Twin DB-10's and wanted some awesomeness to go along with them, Merica`! They are really well designed and built (American Made & a Life Time Warranty with Great Customer Service). The Follower Runs on a great anti-tilt rail and feeds and holds 42 rounds flawlessly. Some fitting is required for a smooth drop-free operation, at least on DB10's. I used 500 grit sand paper on the front and back rib (more so on the back) It really doesn't take much. Then I buffed/polished them lightly over sanded areas and while I was at it I did the same to the followers. Clean, Lightly Oil, and your set. Some reviews I have read trash talk these for fit and function... Well good luck finding anything else like these! (My Magpul 25rd PMAG's & Taran Tactical +5's make 31 for $62) A little effort goes along way. Length: 11 3/4" Empty Weight: 9.4oz. Loaded Weight: 42rds of 147gr FMJ's 45.2oz/2lb 13.2oz. Strap 2 of them together you have 84rds @ 5lbs 12oz.. The Beta C (100rd Dual Drum) Empty is 5lb 4oz. and Cost $450+ These things really are a blast,/ They will turn your standard AR-10 into what seems like a mag fed M60! Take out fields of water/soda jugs, watermelons, or pumpkins. The smile on your face and the raised eyebrows of others at the range is priceless. GET SOME! Pros: Holds 42 Rounds! Cons: Minor fitting for drop free function

Don't know if I would buy this product again.
Had to file down the front rib flush to the mag, file some off the back rib and shaved a little off the smooth side just to get it to fit. They fit nice now. Cons: You have to modify it to fit

Ok I guess.. It works at least.
I bought 2. The first I couldn't get to fit my Diamondback DB10 except by sanding it down. By the time it was tight in my rifle, the polymer was so thin that it started to crack. The other one, I only had to sand down a little bit and it fits great!. It's also pretty thick still. If you are going to buy these, sand the front and not the back. The front is a lot thicker and you can take quite a bit more off of that and get it thin enough to fit. I'm going to buy 2 more probably and see if I have the same results with the next two as what I had with the second one. If that's the case then I will be buying a lot more. Side note: I bought the $99 50 round drum and I can get 5 of these for that price. Even if a couple of them I don't sand right it's still 3 40 rds vs 1 50 rds. Pros: Holds 42 rounds. Cons: Doesn't fit unless you sand it.
