AR-15s

Fwiw…I treat my AR mags same as my 1911 mags as far as maintenance. I rotate the ones I keep loaded every six months. I replace all those mag springs every three years with new Wolff springs. May not make a difference but it’s cheap and gives me peace of mind. Those mags are used for regular practice and have never had a mag related stoppage that I can tell. Matter of fact my 1911’s and AR-15s run flawlessly with my handloads in competition and practice. Can’t remember the last time I’ve had an alibi in a match or jam at the range. All my mags are numbered and I’ve culled any that gave issues years ago.
