Wow. Just like I said. A different slot to fir the auto seer. other than that slot, what's different? You can take the upper from the m16 and put it on the AR with no problem
How hard is it to change a barrel with the ramps in it? 30 minute job if you drink coffee and take your time?
Have you are ever adjusted for ramps to the barrel? If so what is the process?
That's why I said swap it for a barrel that has the right ramps. It's not hard to do, and you can order parts on the internet.
It's obvious you have never built a military grade M4/M-16... You're talking out of your ass… LOL
Most ARs come standard with m16 rails anyway, but why would you need them with a non FA gun? Like I said from the first. An AR is not a sporting rifle designed for varmints. It started life as a military weapon and the only substantial change is to prevent full auto.
False, an m-4/m16 is military grade, they will pass military muster. Thus a military weapon.
An ar15 will fail military muster. Thus just a sporting rifle.
There is a reason for standards.
The fact is, an ar15 only similaritys to a m-4/m16 are cosmetic. It's just sporting rifle just like any other semi-auto...
It's not a bogeyman asshole
