Well it looks as if I have been sold a Crankaroo instead of a C2 Crank, thus it not fitting the cheek rests correctly. Oh well ... Live and Learn! So, I know it will work with the Axiom, Eclipse Xt and the Matrix 355 without the Cheek Rests on. And the pin was just a tad tight (few thousands) on the Nightmare. So, still usable with what I have now. just wished I could remember if it was a forum member I bought it from or if I ordered it. I know my Tac-Pacs all came from a forum member, oh well my fault for not being sure. sorry folks.
Just what the title says.
Here's what I did last night.
Matrix 355:
Added the Guardian Anti-Dry Fire
Replaced the Tact-Zone with a Twilight DLX
Had already added the Tac-Pac to it last deer season.
Nightmare 335:
Added the Tact-Zone from the Matrix
Added a Tac-Pac
Insert Crankaroo everywhere I wrote C2, as I found out all this time I had a Crankaroo instead of the C2 ...
Also, On the Nightmare 335, the hole in the back of the stock for the C2 Crank was a tad off and would not accept the crank at all (this is with the cheek rest off btw), so I bored the hole it just a smidgen more (few thousandths). The C2 Crank will now go on, the locking pin is still very tight screwing in, but I did not want to make the hole any bigger, so hopefully time will wear it in so it works slicker. Works fine on the Matrix 355, not modification need.
Part two of the C2 Crank issues, with the Cheek Rest on the Nightmare 335 the C2 Crank would not fit onto the stock at all. So, once again I went to modifying. Looking at how the Cheek Rest was curved slightly near the top, I was pretty sure it would fit the rounded end of my belt sander just about perfectly.
So, to the basement I went or the mad scientist/fabrication lab, which ever sounds more appealing to ya lol. At any rate, I carefully positioned the curved section to the belt sander, I had to be careful here as to much material off and it would be ruined. and took off about 3/16 of an inch of the Cheek Rest at the curve only. I then sanded with 400 grit the edges, front side and back side, to match the original shape of the rest. You have to look close or you can't see the small extra bit of curve on the Cheek Rest. I re-installed the Cheek Rest and attached the C2 Crank to it and it was just perfect, about 1/16 of an inch gap between the cheek Rest and the C2 Crank when attached. Looks dang good to if I do say so myself.
Still need's a tiny bit of finish sanding to even everything out, but not bad at all. I'm a bit OCD about things like that lol.
BTW, The C2 Crank also would not work with my Axiom and Eclipse XT with the Cheek Rest on, so I assume it would be the same for the Matrix 355. At any rate just in case I am not the only one with this issue, there's your fix.
Caution: Be very careful that you do not ruin the Cheek Rest. If you do not feel comfortable doing what I did with the belt sander or whatever your using, get someone who is good at using these tools to help you.
I do this all the time, as I modify computer cases (known as Modding) into custom cases and custom builds. So, I am always cutting, grinding, fiber-glassing or whatever it takes to get the desired look I want. lol
Any way, that is what I did last night. Now, to sight the scopes in and have fun.
