|Bought an original "first run version" of this mag about a year ago. Aside from the color (Black was all that was available then), I was very pleased with the quality of this mag - Not a single feed issue, held the bolt open on last round, mag fell free, etc.
So, I decided to purchase three more (a second one in Black and two in the now available Dark Earth.
CTD shipped ridiculously fast (as always), but the two DE mags I received, contrary to what was printed on the package, were OD Green. Not a big deal, as I basically flipped a coin when deciding between DE & ODG.
Went to the range and, to my dismay, both "Black Versions" ran like a dream, but the OD mags were trouble from the moment I hit the bolt release. Rounds consistently hammered into the receiver just below the feed ramp on my AR - only a mag drop and tug to the charging handle could free the jammed round. If I did manage to feed a round into the chamber; 90 % of the time, the bolt would not pick up the next round in the mag and instead closed on an empty chamber. Dejected, I went home; But after a lot of experimentation and observation dry cycling, I figured out that the OD mags must be formed from a different mold than are the black ones as they consistently sit lower in my mag well.
HOWEVER, I have a pre-ban Armalite M15 Carbine that lacks M4 feed ramps. Judging by where the rounds were impacting in my receiver...I'd venture that these mags function correctly in AR type rifles with the extended M4 feed ramps. I went back to the range and noted that if I kept upward pressure on the mag while firing - there were zero feed problems. In summary: If you have M4 ramped AR or your M16 mag compatible rifle will tolerate a slightly lower mag lock-up; These mags should work great - regardless of the color. If your AR/similarly specked rifle sounds like mine - stick to the black versions of this mag. I hate to rate these at 3 stars, as they are a great value when they work. I hope Tapco gets their mold issues sorted out as they did with their polymer Mini-14 mags (2nd Gen versions of that mag run like a dream!). For this reason, I'll give 'em another look in the future. Safe shooting.|
