Pretty simple, I'm looking for something different than my current selection of multiple m4 AEGs. So my options: Tippmann M4 - have the old paintball gear, just want an "air" gun with all my AEGs. A&K M249 - can use my M4 mags, can shoot lots of bb's, and can scare people with the volume of fire. (I run DMRs, so I'm not a crazy full auto guy) I'm leaning towards the Tippmann just because I want to try the HPA stuff, I'd run CO2 inline though, and I'd like a rifle that's a bit more realistic. The 249 is for S-n-G's. Always wanted one, just been meh about getting into a new style of AEG gearbox.
