Promag 870 extension tube quality?

[cdncowboy]

I'm looking for a 2 shot extension tube for my rem 870 and the promag one over at hical is a great price... is it any good? I'm not overly familiar with the various brands of extension tubes but it seems to be well built out of aluminum.

Thanks all.

I purchased the mag extension from Hical for my 870 and it is of excellent quality. A mag clamp is not necessary as it is heavy gauge aluminum and very rock solid. On the Hical website it says it is Promag brand but it is actually ATI. It is a 2 shot extension but I can actually get 3, 2 3/4" shells in it for a total of 7 in the tube + 1 in the chamber... highly recommend.
