Put Plinker tactical (note the correct spelling) in the search window. There are at least three long threads on the subject.
I don't have any first hand experience with them but the reviews seem hit or miss. Some people have issues others do not. It seems like the newer ones might have gotten the bugs worked out. I'm tempted to give one a go if my Promags don't ship soon.
Bought 1 just to see for my self and it just arrived today. Out of the package I do not have that gap problem. It will be several days before I can try it. Will let you all know.

Duct tape fixes everything! Well.... almost!
You could even go high class and use the camo duct tape. lol
