Howdy all.
I picked up 8 of the BC 10/22 x 25Rd mags. I haven't had a chance to fire off any rounds from them yet but I have a hunch that they are going to fail me.
The problem I see is that when inserted & seated into the magwell, if a
small amount of pressure is applied to the front of the mag, the mag will move rearward which in essence tilts the top of the mag down. The magazine will remain seated in the mag well but stays in this tilted position which causes the nose of the bullet to hit the bottom of the chamber, like a car hitting a brick wall. Push the magazine forward at the bottom, the mag tilts back to the correct position & the bullet is lined up to feed properly.
On the front of the mag's mouth, there is a round detent which fit's into a hole at the front of the magwell. The detent seems to be too short to get a positive hold into the recess. In other words, the detent doesn't hold and the pressure allows the detent to pop out of the recess.
Anybody else see this? I bring it up because of the reports of mags not working with the first 5-6 rounds. The spring pressure coupled with the recoil, I wouldn't be surprised if the mag moving/tilting isn't causing the malfs... If this is causing jams, the bolt is locking open with the bullet nose hitting the bottom of the chamber, if once the magazine is pushed forward, the bolt closes- that's the problem.
I'll put some rounds through the mags this weekend, but I'm not impressed upon first observation.
