I don't know if I'd describe a bolt knob as <span style="font-style: italic">"formidable"</span>, but if you want to <span style="font-style: italic">"do it right"</span> I highly recommend that you contact <span style="font-weight: bold"><span style="font-style: italic">"monteboy84"</span></span> here on the Hide or over at Sniper Central to see if he'll install a Tac Ops Bolt Knob Conversion on your Mark II. The Mark II has a rather skinny bolt handle shank so the install is a bit different than on a Remington 700, which has a larger, squarish bolt handle.
<span style="font-weight: bold">Also, the TOBKC IS NOT a DIY install - it requires <span style="font-style: italic">competent</span> TIG welding, surface grinding, and finish work for the best results.</span> I mention this because I've seen a lot of hack-jobs where people didn't properly install the TOBKC by welding-on the hardened, threaded insert and then finish grinding everything smooth. <span style="font-style: italic"><span style="text-decoration: underline">If desired</span></span> the bolt handle can be lengthened by about 1/4" over the stock length. <span style="font-style: italic">If a stock length bolt handle is desired, the bolt handle needs to be shortened (about 1/4") before the hardened, threaded insert is welded-on. This will provide a shorter OAL bolt handle like with the installation of most other BKCs'.</span>
On the Remington and other "square" bolt handles, not only can you lengthen the bolt handle with a <span style="font-style: italic">properly-installed TOBKC</span>, but a properly-installed TOBKC also provides a smooth transition from the bolt handle shank to the bolt knob. Most other bolt knob installs give you a crappy-looking, abrupt change from a square shank to a round bolt knob.
Below are some photos of a TOBKC on a Tac Ops Green Hornet (base rifle Ruger 77/22), as well as a TOBKC on a RH Tac Ops X-Ray 51 (base rifle Remington 700) compared to a competitor's BKC on the competitor's LH rifle (base rifle Remington 700). Notice the differences in the length of the bolt handles and the shape of the bolt handle transitions from shank to threaded area.
