Mine does. But I dont use military clips, I use the 5 round Stainless clips used by Across the Course Bolt Gunners (sold by Brownells). I have a bunch of GI clips for the M14, but I found the commerical (High Power) clips work better.
The other day, I said they all do, and got reminded of one that doesn't, the Mosin-Nagant clip. It has to be removed manually. Otherwise, AFAIK, they all do, an important point in getting the rifle back in action as soon as possible.
Yes, L-E clips do pop out, but if loading ten rounds, the first clip has to be pulled out manually. Same with the G-41's and G-43. The Tokarev clips are M-N clips and don't pop out. SKS clips pop out, as do M14 clips.
