Just got my griz 15" mag today, hopefully try it out this weekend.
It appears to be a great value, IMO fit, finish and function are excellent for the price point.
What I like;(in no particular order)
-mag fed
-short oal
-front sight style
-magazine's are well built
-mag swap's seem to be easy and quick.
What I don't like;
- rear sight is cheezy, I like the ghost ring much more.
-screws that hold on the plastic heat sheild kinda stand out and not in a good way
-smells like everything that comes from China with rubber in it.lol
Future upgrades I hope someone makes;
-an upper rail with a dot and a flip up rear ghost ring sight
-Fibre optic front sight
-Knox stock
-a mag release lever that's shaped better and is easier in the thumb.
-a belt with some form of mag pouches or magnets.
-more mags....
Overall at this point I'd rate it very highly
