How reliable are colt mag guns?

[crossgun]

NO issues at all running COLT QC10 Lower, QC10 Side Charger upper, Taccom Barrel and Brownell's Mags with TF +10

Metalform/PSA mags are better than the ASC mags. The springs are a bit too stiff in the ASCs, and they are more roughly made. No issues with with metalforms in my BCP lower, Faxon bolt, Vltor upper, and Ballistic Advantage barrel. I need practice doing mag changes.

Mine has been great. Brownells mags.

My Rock River LAR-9 is extremely reliable and I use only Metalform mags.  Literally zero failures in about 2,500 rds.  The only downside to the Colt SMG pattern is reloading, which should be rare if you have extensions (I use TF +10's on 32 rd mags).  In the case of classifiers with mandatory reloads the mags can be downloaded enough to relieve that tension.

Taylor Freelance now makes a 63 rd mag on the Colt pattern.  I saw one in use at a local match.  Flawless on all stages.

my Stag and my ULW 5.25" Taccom w/Quarter Circle lower both run 100% on Colt mags... I prefer ASC mags..
