These are horrible NC star garbage, I tried fixing them and it won’t work so now I’m trying to find surplus stripper clips that actually work. Yeah you get 20 for 5 bucks but when your stripper clip jams like 2 inch in your mag you will regret these things. Do not buy unless you are looking for useless pieces of metal laying around.
Cons: The clips are non-functional. Cheap thin metal. The cartridges jammed while trying to push them down into the gun and some cartridges fell out of the clip while trying to load the gun.
I found some surplus stripper clips on EBay. They work perfectly.
