Magnetospeed error 2

[lennyo3034]

Is anyone else having this problem? My sporter isn't reading anything and only gives error 2.

The instructions say excessive line twist but it's not twisted at all.

Call MS. See what they have to say.

I must be lucky, as my MS 2 has been working fine for a few years now. Many hundreds of rounds over it.

use cardboard level it muzzle device raised a bit that was my error 2 . keep plenty good battery, good alignment, write down settings for each gun including spacers used. All my errors have been settings or keeping it level with the bore
