[QUOTE="Hugnot, post: 2589764, member: 115658"] Misalignment problem - shims or bed 1st, lap 2nd Old FN/Browning Mauser receivers did not have exacting exterior dimensions. Best way is to bed Tally bases with epoxy but be sure to follow instructions - not to glue bases on receiver. I like JB SteelWeld. Shims cut from aluminum pop cans sort of work but are tacky. Burris Sig Zee rings are real nice & Warne makes FN Mauser bases, including front extension bases that will work with Burris Zee rings having eccentric plastic inserts. Lap just enough to make ring inner contact surfaces level. Scope tubes are tough & sort of springy but don't bend them. Reversing lap bars to go flat end to end seems to work better than pointy end to end for alignment determinations. [ATTACH alt="IMG_1099.JPG"]384068[/ATTACH] Bedding instructions - from Murphy site but will work with other bases. [URL='http://www.murphyprecision.com/Page/Scope_Base_Bedding']www.murphyprecision.com/Page/Scope_Base_Bedding[/URL] For 2 piece bases use lap bar for ring alignment. Be sure to apply wax/release agent to receiver, screw holes, & screws - don't glue bases onto receiver or glue screws into base(s) or receiver. A quicky solution would be aluminum pop can shims, Warne Bases & Burris Signature Zee Rings. Then center scope reticle & adjust ring inserts for optimum bore sight. [/QUOTE]
