Yes, probably spoken by one of the fanboys for the 5 flavor-of-the-day manufacturers who only make 1:7 twist barrels on their AR-15's. The truth is 1:9 will work perfectly for up to 69-70 grain .223/5.56 bullets that most people will use and will be as accurate as you could want. Some folks have reported using even heavier grained bullts in their 1:9 twist AR's with great success, but it's a crap-shoot as to whether your own rifle will do so. As was stated above, the fast twist barrels were developed for the military to stabilize tracer bullets in short barreled, full auto. M16's & M4's. Somehow from that, many civilian semi-auto. AR owners jumped on the bandwagon and asserted that every AR needed to be 1:7 twist barrel or it was junk. Nothing could be farther from the truth.

As a general rule I'd say if you're mainly shooting 62gr and below 1:9 is a good choice. If you're mainly shooting over 55gr then 1:7 is better. As you can see there is overlap and we haven't mentioned 1:8. Wrap your head around the subject before you choose. I wouldn't buy anything until you get up to speed.

There isn't much point in converting it to full auto. It's expensive and you'll just annoy everyone at the range.

As you see, most here people here don't seem to approve of the idea, but take no offense, they're legitimate answers to your question. I've thought how I could go about making mine/getting one fully-automatic and came to the conclusion that it's not worth it (at my budget.)

If you have some money to spend on ammo, you might want to ask the guys running the range if they have a registered LEGAL full auto they will rent you for the day. Cheaper and less headaches than going through the headache of buying a NFA weapon. Knob Creek gun range at West Point Kentucky has them where I live. May be one in a location near you.

Also, if you really wanted to shoot full-auto enough, you can even get a bump fire stock and see how that feels.

I would say yes troll. Even non gun owners know full auto guns are illegal with out permits.

if you are wanting to cover the most space in a close area get a shot gun. in a 75 meter area a mossburg 500 with a 24 inch barrel and 6 00 buck shot will probably do more damage than a AR 15 in full auto with 30 rounds.

I have had someone at the range ask me if my AR was full auto. I think that just the look of the AR, uninformed people just assume.
