  1. You won’t be denting a titanium magazine tube. I had a video where they were driving over a piece of the same diameter tube stock with a truck with zero deformation.

     

    Driving over it with a rubber tire truck is a bit different than a sling letting loose and the gun falling three feet onto rocks.

    The truck test has little merit IMO.

  2. Here is a pic of my rear C stock mount. No drilling. Very strong mounting platform. Mounted for several years under heavy use.

    Blessings...

     

    I’ve considered that mount. As discussed earlier, it doesn’t sit into the sling loop slot very well. I believe a bit of blending would help it considerably. Thought I would try something else....never hurts.

  3. I keep all the factory pieces.

     

    A few years ago a guy was looking for a factory tube on the cheap. Seems he dropped his M4 or it fell over.

    He had stated there was a gouge and a finish math he didn’t care for. Someone sold him a tube for $35

  4. I was concerned about the aluminum but 316 and 7075-t6 have similar tensile strengths...and shear strengths. To me the biggest issue would be the elasticity values where 316 has about double, or more, than that of 7075-t6. I'll ask my engineer friend about other factors.

     

     

    I think you may be over thinking it a bit

  5. I wouldn’t think an aluminum screw would hold up well, but it is just a buttpad.

    I would be more inclined to use a steel fastener with zinc based anti seize compound if I were extremely worried about the dissimilar metals.

  6. I believe one must consider the weight differences when comparing the metals. Most discussions always have strength to weight ratio factored in.

     

    Being from the aircraft industry for the last 32 years, I have a bit of experience with the lighter weight alloys. I really don’t care to get into a debate, just wanted to interject the above. I’ve always used steel tubes, the few ounces of weight savings is not worth the cost, IMO. Then there is the issue of running an aluminum follower in a titanium tube. The clearance is large enough to prevent galling, but the idea makes me cringe.
