Joe Chacon/ABRA mechanical rear rest tried for the first time yesterday at Kokohead.
It is amazingly stable and easy to consistently put the rifle back to battery. The rear "dog bone" made of delrin plastic makes it stable
Has elevation and windage adjustments, although once leveled with a bubble level and centered, I usually only move the adjustments on
the front rest.
It is 7" x 8" made of aluminum - a lot smaller and lighter than I thought, but very very stable.
The rest had surface imperfections - nicks, scratches, and rough machining marks. I took the rest apart, and took #220 wet sandpaper to the whole thing,
and now it looks "okay". I might go through graduations of wet sandpaper to get a nicer finish when I have time.
The elevation wheel was off-center and was lop-sided. It moves in an elliptical motion instead of a round motion. However, when using the rest, it doesn't affect
usage or performance.
Having used this, I think my new Edgewood rear bag will be staying home from now........... auwe !
**Over the span of 2 evenings, I used #220 wet sandpaper and Flitz paste to give it a going over to clean up some of the dings. Came out okay....see pic on right
*** Doesn't work well with narrow "V" sporter butt stocks. The delrin dogbone where the stock rests doesn't hold a narrow V stock. It wobbles and cants to make this rest ineffective.
Butt stock has to be medium/thick so that it touches the 2-sides of the V and sit well in the dogbone.
