A few weeks ago I took a tactical rifle and pistol course using my Mini-14 as the rifle. That course was obviously intended for AR pattern guns, as telescoping stocks, red dot optics, and trigger-finger magazine release button systems were critical to meeting the short time limits. I was slow at swapping mags on my Ruger Mini 14, and while I haven't shot that gun much recently, back in the 1990s I was shooting it a lot, and I really knew it like the back of my hand. I also shoot an M1A and an AK-47 pretty regularly, and those magazines have the same type of release lever and toe-to-heel procedure to insert a new mag. You just can't stick on straight up into the receiver; it won't lock in if you do that. What techniques do y'all use for getting faster magazine swap times on your tactical semi-auto rifles and carbines? Are they any videos online showing the method you use? How fast can you do a mag swap? I am guessing that I can do a mag change TWICE AS FAST with an AR-15 than with my Mini 14, my M1A, or my AK. There's a video on Youtube-- I saw it recently, but forgot to save the link or write down the name of it or the user who posted it-- comparing the magazine swap times on several different rifles with several different shooters (all experienced gun guys). The AR-15 was the clear winner. Here's the drill they did: With a chambered round and a magazine with one more round in it in his gun, the shooter stands at the low ready position. On the signal of the timer, the shooter raises the gun and fires twice (as rapidly as possible while hitting a big steel plate most of the time, about 25 yards downrange). Then the gun will be empty, both in mag and chamber (bolt may lock back on some models, but not the AK). While the timer is still running, the shooter drops the empty mag, inserts a new one, closes the bolt or otherwise chambers a round, and then fires 2 more shots ASAP. The timer stops after the 4th shot is fired: RESULTS: AR-15 in .223 was the fastest gun, with the several shooters all doing quick mag changes without any fumbling or cursing, with an average time of 6 seconds from the "GO" signal to the 4th shot going downrange. The AK was second place, but it required 9 seconds on average, and that's NOT counting the one guy who fumbled with the second mag and had a hard time getting it to lock. The M1A / M14 was even slower, with another shooter having a lot of trouble, and his 15-second time was not even counted. They threw that out and only averaged the rest of the shooters' times, and got 11 seconds. Strangely, the Century Arms CETME / C308 was the worst one, at 13 seconds. That one has fairly short and handy 20 round mags, an easy-to-access push button release system, the new mags go straight up into the slot with no tipping or rock-to-lock technique. But they were slow anyway. Maybe the light weight aluminum magazines, when empty, did not drop free and had to be pulled out by hand. The fact that it didn't have any "locks open after last round" feature probably combined with the odd and unusual operation of the charging handle (located way forward on the left side of the barrel) made this a really slow one.
