Hello all, Just a summary of want I am looking to do. My wife and I are looking for a back yard plinker to stay in practice with our 5.56 AR-15's. A lot cheaper and more convenient. I am not expecting a nail driver, but would like to be able to consistently hit soda cans at 50 feet or so. Don't hate me for this but, we bought a Black ops M4 Viper at ****'s. It was accurate, and pretty nice, for 3 weeks. Trigger broke, and replacement lasted less than a week. We will be shooting at least 4 times a week I would say, and average 4 mags per session. We did put almost 10,000 rounds through the 1st black ops. Yes, in 3 weeks. I am looking at 3 different M4's. G&G Combat Machine M4 Raider with Polymer RIS AEG Echo1 Troy MRF-C AEG JG SUPER ENHANCED M4 CQB SOPMOD RIS I am leaning towards the Echo 1 or JG Any helpful input would be greatly appreciated. Not looking for a fan boy brand war, just facts. Thank you.
