"A Sully Review:

Overall: Solid, consistent mags, that are not prone to letting you down often.

1. Tough - able to take a drop without bursting into tears (or pieces).
2. Consistent FPS. (Oh mercy all of the FPS.)
3. The 500's hit like bricks - they put rounds down range like they mean it.
4. Realistic weight - feels about like a full 30 round mag should feel.
5. Realistic capacity. A nice comfy home for 30 rounds (I think you can get 38 or so if you must have those first few practice shots).

1. Torque screw - you'll need more than just a penny to twist the C02 screw shut. Hand pressure just isn't enough, you should have a wrench lest you go through a box of C02 cussing like a sailor as each one bleeds out. Ask me how I know.
2. The 500's hit like bricks. (This is a pro for me because I like people to yelp when they're hit.) However, be aware of which mag you purchase as the 500's may very well be verboten on many fields - especially up close.)
3. Realistic weight. Another duplicate, I know... but again, I like MilSim vs. 4000 rounds per minute capture the flag. If you run a legit rig, you'll feel the weight up front if you try to pack in seven of these mags.
4. No way to check the number of rounds remaining - a translucent panel would be handy, but hey, count your rounds and quit whining. :)
