Mag extension tube for Mossberg 930?

[BHPFan]

Can anyone recommend which is the best Mag extension tube for the Mossberg 930?

I like to purchase one that will give me between 7 to 8 shots in the tube for the 930 combo (18.5" and 28" barrels).

I see a lot of brands (SureCycle, Choate, TacStar), but I like your opinion on which one works best.

Thank you.

I did research on this also and choate seems to make pretty decent ones. Choate makes the 7 tube that will fit flush with 18" barrel and if you have the 28" barrel you can get a 10tube that would not extend pass the barrel. They also sell the pistol grip stock. Here is a good review on the 930 that some guy wrote up on weapon evolution.
