Reviews & Ratings for Matador Arms Mag-X Conversion Caliber — 10 reviews — Page 1

Bought so the wife can shoot 2 gun with her 320 and an ar pcc without different mags. Seems to work fine.

To whom this may concern, here is my review; I've owned both Matador Arms Montigo (Junk) and the MAT-9 (Junk) and I have yet to make it through a full Magazine. After making 4 different Extractors for the colt Mags I purchased this "MagX P320 AR Adapter" from Optics Planet. Once again I have been duped. Nothing works, DD lower, Geissle lower, Colt Lower, DPMS Lower, Anderson Lower, JL Billet Lower.... The p320 Magazines don't even fit this MAGX P320 adapter, which is insane, I had to pull out my P226 Legion Magazines, it fits but something tells me it will fail to cycle or choke, FTF all the same to me. I'm over it, I wish I could just get all my time and money back. All Junk, so much money into this build to be consistently mislead. Just buy a Centry Arms MP5, it's HK tooling anyways. Selling this upper first chance I get. I would not recommend anyone even taking the risk to use this as a means of protection or even plinking. Matador Arms, haaaa a Matador has integrity and Honor this thing was built buy morons and most likely the Chinese (at least they can build a Ak-47). I have tried to play nice, broken firing pin, this broken that broken.... save your money.... I am a combat veteran and have used and built hundreds of rifles and weapons, this is by far the biggest failure and piece of junk of all time. God Bless!! End Rant.

Using the Mat-9 upper with mil-spec lower
Used 3 different Glock mags:

OEM—FTF, round after round, it just can’t seem chamber the the rounds.
ETS Gen 2–worked the best out of the 3 but seldom has FTE and double feed malfunctions.
Amend 2–doesn’t even stay in.

This Magazine adapter fit perfectly. Tried it in an older and newer PSA AR-15 mag well as well as my Aero lower. All of which fit perfectly. The Aero was a little more snug than the PSAs but I had no issues with the fit and function of the 15, 17, and 21 round P320 mags that I have. All Sig made mags. I’d assume they’d work with the cheaper mags as well.

TOP QUALITY FIT. NO PLAY PERFECT MACHINE WORK. FUNCTIONS GREAT.

It works as advertised.
Smooth feed and good ejections. It appears to be robust well machined adapter. Easy to use.

I may be an outlier, but the M&P version of this adapter has worked perfectly for me with a couple of mil-spec lowers. I've had lots of trouble with the Stern Defense version -- not feeding the last round and not working at all with non-S&W mags. The Matador has worked fine with all the mags I've tried through it.

doesn’t fit in a 9mm upper if the barrel has a feed ramp. Would have been nice to know that before purchasing. I’m going to modify the aluminum frame and see if it will feed/cycle reliably, but the add and description is complete lies. Recommend a competitors product.
