fiber optic sights

An optical fiber is a glass or plastic fiber designed to guide light along its length by total internal reflection. Fiber optics is the branch of applied science and engineering concerned with such optical fibers. Optical fibers are widely used in fiber-optic communication, which permits digital data transmission over longer distances and at higher data rates than electronic communication. They are also used to form sensors, and in a variety of other fiber optic sights.

The operating principle of optical fibers applies to a number of variants including multi-mode optical fiber optic sight, single-mode optical fibers, graded-index optical fibers, and step-index optical fibers. Because of the physics of the optical fiber, special methods of splicing fibers and of connecting them to other equipment are needed. A variety of methods are used to manufacture optical fibers, and the fibers are also built into different kinds of cables depending on how they will be used.

Rifle Scope

For example, with a typical Leupold Rifle Scope brand duplex 16 MOA reticle (of a type as shown in image B) on a fixed power scope, the distance from post to post (that is, between the heavy lines of the reticle spanning the center of the scope picture) is approximately 32 inches at 200 yards, or, equivalently, approximately 16 inches from the center to any post at 200 yards. With a known target of a diameter of 16 inches that fills just half the distance from scope center to post, the distance to target is approximately 400 yards. With a known target of a diameter of 16 inches that fills the entire sight picture from post to post, the range is approximately 100 yards. Other ranges can be similarly estimated accurately in an analog fashion for known target sizes through proportionality calculations. Holdover, for estimating vertical point of aim offset required for bullet drop compensation on level terrain, and horizontal windage offset (for estimating side to side point of aim offsets required for wind effect corrections) can similarly be compensated for through using approximations based on the wind speed (from observing flags or other objects) by a trained user through using the reticle marks. The less-commonly used holdunder, used for shooting on sloping terrain, can even be estimated by an appropriately-skilled user with a reticle-equipped scope, once the slope of the terrain and the slant range to target are both known.

Glow Sticks

Dynamo lightSince batteries can be a burdensome cost in developed countries, let alone in the third world, the development of self-powered Glow Sticks s a welcome advance. Some use solar panels to recharge their batteries during the day.

Colt 1911

I want to make something happen. I always try to be fair in my dealing. I understand FN is no longer going to import the Hi Power; take that for what it’s worth in the effect on values.

Well I think I lost it. I offered to buy a Colt 1911 and Colt 1903 sight unseen the other day. The price seemed right so what the hell. Well the gentleman showed up with it and I bought it. I have to say I’m not a fan of nickle plating but it’s growing on me.
I can’t figure out the barrel set up. The barrel sticks out the front a half inch? It looks like a bull barrel with no bushing. The guide rod is a full length one in blued.
What should I do with it?
1) shoot the living tar out of it?
2) Find the proper parts and return to stock?
3) Is there a way to change the finish on this or is the nickle finish permanent?
4) Pimp it out with these?

Ruger 10/22

The benefits of the Ruger 10/22 are many, and vary by model. The standard 10/22 Carbine, virtually unchanged since introduced in 1964, is the most popular .22 rifle of the last 40 years; the Ruger Deluxe Sporter features a cut-checkered walnut stock with a flat buttplate; the Ruger All-Weather 10/22 features a stainless barrel, clear anodized rust-resistant aluminum alloy components, and a durable synthetic stock;
