    -5 groove, probably R form
    -2771 or whatever it says would be serial number (pic went away when I started the reply)
    -Steel lot "L"? (Internal info for them)
    -"S" for stainless,? I don't know why it wouldn't say SS

    Have you considered going straight to the source ... Benchmark Barrels - Contact ?

    <H2>Benchmark Expands Centerfire Barrel Line

    Benchmark Barrels of Arlington, Wa [​IMG]
    Centerfire Barrel Production
    Benchmark offers a full range of centerfire calibers now, from .22 all the way up to .50 caliber. The three-groove, standard land, 8-twist 6mm barrel has been shooting exceptionally well, and Benchmark recently acquired new buttons so it can deliver 1:7″ and 1:9″ twists too. The 6.5mm barrels and 30 caliber barrels have been shooting very well also according to match reports. Benchmark can deliver both canted-land and conventional land versions of its centerfire barrels. Which shoots best? According to barrel-maker Ron Sinnema, “the 6mm 3-grooves with standard lands are working great. Bruce Baer tried one recently and said is was exceptionally accurate.” And for customers who prefer cut-rifled barrels, Benchmark now offers cut rifling in most bore sizes, from .22LR all the way up to rifled shotgun bores.

    The info you found here is almost correct... But, we do not make cut barrels, only pull button.
