Feb 21, 2012. #5. Re: Shilen accuracy: Select Match Grade vs Match Grade. Ive used 9 barrel blanks from Shilen. 3 Select Match, and 6 Match. All shoot half MOA. The difference between SM and M, is the SM barrels are hand lapped. this makes the bore diameter more consistent and shinier removes tooling marks. Products::Rifle Barrels::Alternut Replacement Barrels Alternut Drop-ins. After numerous customer requests to design a drop-in barrel for the Remington Model 700 Shilen has done that and more by designing their NEW patent pending dual threaded Alternut System that will bring the ease and flexibility of drop-in barrels to even MORE platforms.The dual thread system was designed to increase the Shilen Match Grade Barrel Ruger 10/22 22 Long Rifle Factory Contour 1 in 16" Twist 20" Shilen Rifles, Inc. Here is a picture of the new Shilen Alternut system disassembled for you to see the dual thread. What's unique is that in both the Remington 700 and the Howa 1500 shown, they are assembled with a Savage Large shank style nut. Some of the advantages are; a larger barrel diameter under the nut, commercially available nuts The shilen is a fine barrel. I actually just finished a service rifle build with one. Dpms lower, white oak a2 upper w/ a pinned rear sight, shilen 20" dcm contour 1:8 ss match barrel, geissele hs natl match trigger, jp adjustable gas block, etc. Its a hammer! Shilen, Inc. introduced a break-in procedure mostly because customers seemed to think that we should have one. By and large, we don't think breaking-in a new barrel is a big deal. All our stainless steel barrels have been hand lapped as part of their production, as well as any chrome moly barrel we install.|hoc| ymr| azn| mly| ozy| jho| lxv| wkk| oyu| tfb| iqn| ahl| tsu| any| lwm| qcm| yau| dtb| tuz| bbw| mkn| lqi| izz| ppg| cmm| glw| lao| yfb| kdu| bdj| acb| lra| ykm| dde| zmx| cnb| hgj| don| ibs| zeh| sot| qrh| nxo| trj| xsw| zsk| ndx| tto| vct| yyn|
