    I was disassembling a Ramline MAP 9015 BHP 15 shot magazine for cleaning and noticed there was no conventional spring. Best I can tell is there is some kind of spring compressed in the follower.

    I have had no problems with this mag. Are they considered decent or junk?

    Thanks for any input. Bill

    The Ramline BHP mags have a mixed reputation.

    I have several, and I've had quite good luck with them.

    RamLine pioneered the use of an extending coil ribbon spring that is riveted, at the top, to the side of the feed lips (sort of) and attaches to the bottom of the follower. This spring unwinds along the side of the mag as the follower is depressed as rounds are loaded in the mag.

    This spring design allows the follower pressure to be relatively consistent from a full mag to an empty one. Also, since you aren't compressing a spring under the follower, you can sneak a couple of extra rounds into a magazine that is the same size as a conventional spring one.

    Ramline also made other mags, including a 50rd 10/22 mag, using this spring design.

    ftierson summarized the Ramlines well. The vast majority are decent and reliable. There was a small percentage that weren't and that tainted Ramlines reputation for a while. On some of the BHP Ramlines I found they seat high and I have had to file the feed lips down a bit to get proper clearance for the slide.
    Once I did that they worked wonderfully. They fed smoother than about anything else.

    I have one that wasn't consistant in the way it worked, so I drilled out the rivet and converted it to a conventional mag. Much better now.
