The concept is flawed but the weapon magnificent.
How about we cut to the chase and get an upgrade.
We're currently rocking M4's and M-16A4's. They've been serviceable but they're lacking in many areas. If we drop the concept of a hyper accurate Squad Automatic Weapon with limited capability to lay down suppressive fire and redesignate this weapon as our new M-16A5 I think we'll have a winner.
A couple of things will have to happen though. First we're gonna have to admit (well someone is going to) that the concept for the Infantry Automatic Rifle is stone age thinking. In hindsight its quite obvious that we don't need a modern day Browning Automatic Rifle.
Next we're going to have to admit that we lost something when we gave up automatic fire on our service rifles.
OK, I'll do it. We fucked up and now its time to correct the mistake. Let's get this done gents.
Consider it a necking down of our Infantry weapons...no more dual stocks of M4's and M-16A4's....just the M-16A5 formerly known as the M27 and life is good. Well except for qualification day. Standards are going to have to rise again. But that's a good thing.
