Shortest 300 BLK AR magazine?

[Recycled bullet]

I am wondering about shorter length 300 Blackout specific magazines. I am shooting 225 grain powder coated lead bullets through a Ruger American Ranch Rifle. My rifle has the magazine well to accept standard AR-15 magazines.

I think standard COAL for the ar 15 is 2.62

These are the two I'm looking at from gun mag warehouse.

I want the mags to not stick out so far from the bottom.

I like short mags too.
They also keep you from shooting up all your ammo so fast.

*LOL* I just put 5 rounds in the mag and don't worry about how much hangs down underneath!

I would go with the Lancers. The magazine is a pretty important piece of a semi auto. I have zero confidence in Duramag or Promag quality. Also, try to find physical dimensions in the advertising. Many 5 and 10 round magazines are just standard 20 round mag bodies blocked to lower capacity.

I use 10 round Pmags.

They don’t stick out much and always work.

10 Round Pmag for range unmodified for 5.56 and 300, when you get into big pills on the 300 you need to file/sand but no big deal. And then there are the ten rounders I have modified for my hunting 450BM/458, they have worked flawlessly for me!

I use 10 rnd Lancers but have a single shot mag also. Actually just blocks the mag well and you drop one in the ejection port.

I use the 10 round Lancers, in my 7.62x39 AR the 10 round dur mags work great

Actually the standard 223/5.56 OAL length is 2.26 so an apparent transfer of numbers in the 2.62 number.

The P mag can give you 2.30 in length due o a different method or build. So the RN and flat nose bullets give you a bit of extra base to the bottom of the neck in internal fit. The AR-15 lower frame is designed for this magazine length box.

I have a bunch of five shot magazine for AR-15s. So there are plenty of five shot magazines avalible.

It's kinda labor intensive, but it is possible to reduce the length of existing magazines...I have done so with a 6.5 Grendel magazine for my ruger American. Helped enormously with how carry-able it is!
