I discovered Tapco when I found this forum over a year ago and was originally interested in the SKS 20 round detachable magazines. I was so impressed with it I bought some Tapco mags for my AK as well and they all worked perfectly. I more recently picked up a Bushmaster AR, the exact model is, SUPERLIGHT ORC W/ RED DOT. It works fine with the steel Bushmaster mag that came with it and some ProMags I picked up at a show. I later picked up a couple Tapco mags, expecting the same flawless performance I received from Tapco on the Sino-Soviet side, but I ended up with significant jambs and feed issues, maybe every 5 or 6 rounds. I thought I may have some bad mags so I ran them through an PSA and Tactical Weapon Solutions AR, that I have access to and everything works fine. I do not think there is anything wrong with the actual magazines since they work fine in other rifles, but was wondering if there are any known issues or if Tapco is just not such a good fit for a Bushmaster AR rifle. I may just have a picky rifle, and have notified Bushmaster, but doubt they will do much since their magazine works flawlessly in the rifle.
I have tried asking over at one of the AR forums, but got some negative feedback like "Tapco Sucks", probably from people that have never even used one. I do know Tapco makes good products and do know my magazines function ok in other brands of AR. All comments welcome. Thanks
