Will this Magazine fit my new Seekins SP-10, 6.5 CM?

New to ARs here. I ordered a Seekins SP-10 in 6.5 CM yesterday. I believe it comes with a 20 round magazine. I want a magazine that will permit shooting from a bench without protruding lower than the grip. I understand the rim of 6.5 CM is same as 308 so the mags are the same? Will a 10 round PMAG work with no feeding issues? I attached a picture of one to be specific. Thanks in advance.

Yes it will work. Any SR25 pattern mag will work.

Standard 20rd mags don’t really protrude much, if at all from large frame guns:
