Blasers are awesome and available from several sources...I got mine at Epps.
Browning has the takedown BLR, which I find myself lusting after.
TC Encores and H&R single shots take down quickly and usually retain zero when re-assembled.
Sauer 202 and Mauser M03 also take down easily. Probably lots of others as well. I realize this is the Precision forum and most of these don't qualify, but for Blaser, Mauser and Sauer offer more precision than most of us can utilize.
