1. Slide Fire stocks are not made by Magpul.

2. Slide Fire stocks are a joke.

3. Even real full-auto "sprays" bullets everywhere, with huge gaps between bullets, so an untrained shooter would be lucky to hit crap after the first shot. It was devised for multiple troops to fire at the same time, creating a large field of fire to fill in the gaps. Muzzle climb makes it that much more difficult.

4. There are various calibers that are already legal for deer in an AR-15 rifle, so if Slide Fire stocks were a problem, we'd already be seeing it.

5. I have owned a registered, full-auto M16 for over 10 years now. You are more than welcome to come to my home, where I will place a foam deer target at 50 yards for you to try to hit on full-auto. You might be surprised to find that you'd be lucky to hit it even once.
