Pistol Optics

I have red dots on some of my AR-15s. For my wife, this is great. Put the dot where she wants the hole to be, and press the trigger. A hole appears near where the little red dot was.

All of my AR-15 red dots are co-witnessed. The little red dot shows up at the same place where my iron sight points. If the optic is off, I can see my iron sights through the glass. This means that if I have issues with the red dot being “dead,” I still have functional sights.

With the peep sight of the AR-15 platform, I have a rear sight that flips down. Some of my ARs have fixed front sights, and some have flip-up front sights. Even if they are flip-up, I leave them up.

Some pistol optics are set up so that when the optics are mounted, the rear sight is removed. This means that if your optic fails, you have no sights.

I looked into a P365-RS; this is a Sig P365 with a Romeo Sierra already mounted. The sights are co-witnessed. And the sights are the standard great Sig sights.

Holsters

I have been a fan of Alien Gear holsters for several years. I like how they fit and the positive retention they provide for my firearms.

I particularly like their Shape Shift system. This system consists of different shells, which are specific to a firearm; parts to mount to the shell for different types of retention; and a backer.

For example, you can use a positive retention where you have to use your thumb to release the firearm, or it can be retained by a spring loaded catch. Pull, and the firearm comes out of the holster. The tension on that catch can be set as you want.

The tool needed to adjust the different tensions and positions is the retaining nut, which retains the mounting system.

The shell can be used as a half shell with some backers or as a full shell with others.

For me, I like being able to move the holster to different backers: an IWB, an OWB, an appendix backer (which I haven’t used), and a shoulder rig. They have drop rigs and MOLLE rigs as well. There are many options. Those backers that attach to a belt can adjust cant easily. The belt clips are solid loops, J-Hooks or C-hooks. You choose which you want.

The C-hooks fit between your belt and your pants, so the only thing that is visible are two small black lines at the top and bottom of your belt. With the solid loop and J-hooks, you can see the “strap” of black plastic, which is the clip.

I’m looking for another holster for a P365X-Macro. They aren’t selling a shell for the Shape Shift system.

Yesterday I spoke to a rep and found out why. They are phasing the Shape Shift system out. Because the shells mount to the backers at the top of the slide, there isn’t enough room for many of the pistol mounted optics. In addition, pistols with weapon lights don’t fit well either.

According to this rep, they are working on a new system.

Is It Lawfare?

The big news yesterday was that the DoJ is attacking Trump’s political enemies, attempting to jail them.

It appears that the DoJ has found that James Comey is likely guilty of multiple crimes, so he has been indicted. We can tell this is lawfare because they are using laws that have existed for many years; they presented evidence to a grand jury, and the grand jury returned the indictment.

This is totally different from charging a political enemy with fraud for putting up collateral for a loan and then paying back the loan with interest but having a difference in opinion on the value of the collateral. It is also totally different from calling the secretary of state for a state and telling him that you need 200K votes to win the state. AND it is totally different from entering into an NDA agreement with a bimbo who is attempting to blackmail you, and then paying that bill through your lawyer.

You see, this crime is real, 18 U.S.C. § 1001 making false statements to Congress. James messed up and answered directly when asked if he authorized a leak. He should have gone with that old favorite, “I don’t recall.”

While not all the grand jury agreed that he violated 18 U.S.C. § 1001, a majority did.

All the members of the grand jury did agree that he violated 18 U.S.C. 1505, obstruction. Corruptly endeavored to influence, obstruct, and impede the Senate Judiciary Committee’s inquiry by making false and misleading statements.

The case was filed in the Eastern District of Virginia, 25-cr-00272

Networking Almost Working

The wonderful thing about Unix configuration is that you can do anything you want to a configuration file. With a GUI, you can only do what the GUI allows you to do.

My internal network uses OSPF for internal networking with a bit of BGP magic for the OVN networks. Whenever a router is presented with two choices for a route, it chooses the one with the lowest cost.

It is a little more complicated than that because a router can also adjust its priority. Priority adjustments might be used when you have links that have different dollar costs but the same bandwidth.

There are three parameters that are used to calculate the cost of a link. The algorithm calculates the sum of the costs of all the links between two nodes and takes the lowest cost.

The first method and parameter is to set the cost of the link. This is a value that ranges from 1 to 65535. No calculations are done; this is the cost of using this link.

This means that you could assign different values to different link speeds: 1 for 100G, 2 for 40G, 3 for 20G, 4 for 10G, 5 for 5G, 6 for 2.5G, 7 for 1G, and so forth. This works, but it is painful.

A faster method is to assign a reference bandwidth to use within the router. For me, I set the reference bandwidth to 10G. Since the router knows the bandwidth of each interface, it takes that reference bandwidth and divides it by the interface bandwidth.

If my interface is a 10G fiber link, that is 10G/10G, or 1. But if that particular interface is a 1G Ethernet port, then we have 10G/1G equals 10.

This is a quick way to get the correct costs assigned to every interface. I only have to specify a bandwidth for an interface if that interface is a bridge.

Nice stuff.

Because I have a link that is acting up, I was able to describe that link to the protocol. That link is 10G down and 1G up. So it gets direct traffic down, but when it is sending upstream, that takes two hops.

The only issue I still need to solve is that I have an L3 Switch that is not passing OSPF multicast packets.

Question of The Week

Who else do you want to see indicted, and Why?
