rigid
In physics, a rigid body (also known as a rigid object ) is a solid body in which deformation is zero or so small it can be neglected. The distance between any two given points on a rigid body remains constant in time regardless of external forces or moments exerted on it. A rigid body is usually considered as a continuous distribution of mass.
In the study of special relativity, a perfectly rigid body does not exist; and objects can only be assumed to be rigid if they are not moving near the speed of light. In quantum mechanics, a rigid body is usually thought of as a collection of point masses. For instance, molecules (consisting of the point masses: electrons and nuclei) are often seen as rigid bodies (see classification of molecules as rigid rotors).
Hey everybody,
Purchased an Arken SH-4 Gen II already mounted on a 34mm Rigid Precision 20 MOA mount that I don't need. The mount is basically brand new with the previous owner mounting it to an AR-15 and putting a few rounds down range. Looking to trade straight across for a set of Arken...
Rigid Knives Bowie, mod # RG-69 modified clip point. Made by G. Sakai in Seki, Japan. Rare - made between 1980s to 90s. Blade steel: U2X. Overall length 14 inches, blade 9.5 inches. Sheath leather, black, with button strap retention. One owner (un-used), factory edge.

Cleaning out the garage and this needs to go. Pump is bad. Motor runs like a top and the oil was recently changed. It's got the Subaru motor.
Find a cheap chinese pump on ebay and you're in business. You could do worse for fifty bucks.
Will meet up in the Beav/Tigard/Sherwood area-ish.
Running out of room and these must go. One has the tightening lever broken but you can still tighten it to adjust the height no problem. They are going for $33 a piece at Depot. $40 takes both.
Edit: FTF around Beaverton/Tigard/Tualatin/Hillsboro area.
I bought a Vertx Commuter XL 2.0 bag for my 10.5" AR pistol. Love the bag, the discreet carry compartment is excellent, but i was underwhelmed by the main "admin" compartment. It's so big, but has no hook & loop backing to stick pouches to, which seems like a missed opportunity. I wanted to get...
