All the five round AR-15 mags I’ve seen are the same body (length) as the ten round mags. The original C Products & ASC use a bound compressed spring to take up space to limit to four or five rounds. My C Products mag only hold four rounds but I read where CP/ASC counted the chambered round into their stated capacities. My ten round mags hold nine and my fifteen round mags hold fourteen. My E-Landers mags hold the stated capacities ten, seventeen or twenty four rounds.
