CZ Scorpion Improvements

Today I installed a few parts from HB Industries in my CZ Scorpion.

The first and easiest was an extended charging handle on the right side. Installation required drifting the handguard pin to the left, sliding in the new charging handle, and returning the pin to its original position.




As you can see, the new charging handle provides a much larger gripping surface.

The second part was an extended paddle magazine release. I'm really glad that HBI included a spring with it because I managed to drop and lose the OEM spring.





Finally, I installed HBI's reduced power trigger and disconnector spring kit. This required the most work but I had it done in under a half hour. While I had the trigger pack apart I took the time to polish the engagement surfaces with hard Arkansas stones. I also put a bit of Teflon-bearing Superlube grease on the contact points.

Incidentally, HBI has some very well done instructional videos on their YouTube channel.

As it came from the factory the trigger pull was at least 9 pounds. Now it's about 5.5 pounds and much smoother.

These are small changes but should make shooting the gun better.

CZ Scorpion EVO 3 S2 Micro

A gun I got interested in when it was first announced over a year ago is the CZ EVO 3 S2 Scorpion Micro with telescoping PDW-style brace*. This is a shorter, lighter version of the Scorpion carbine and pistol.

CZ's web page for the "pistol" is here.  A good video overview is here.

In light of ongoing leftist violence and especially after the recent Poway, CA Chabad shooting, I decided that having a PDW that'll fit in a laptop bag might be a good tool to have. The Scorpion Micros are still hard to find but I found some on Gunbroker and decided to get one. They are still selling for about MSRP and I don't expect that to change until supply catches up with demand. I took delivery from my FFL last Friday.





I have an old Dell laptop briefcase. The gun fits in it with a 32 round magazine inserted.



Fit and finish on it are excellent. Field stripping is easy. By pretty much all accounts, the larger Scorpions are extremely reliable guns. I'm expecting this one to be as good. What makes it a "Micro" is just a shorter barrel (4.12") and handguard. The action is the same as the larger models.

It came in a cardboard box with manual, warranty card, pull-through bore cleaner, gun lock, two 20-round mags, and an Allen key.

In reading up on the Scorpions, I found complaints about three things: the trigger pull, that the safety lever interferes with one's trigger finger when shooting, and the grip. The trigger pull on mine is creepy and over 8 lbs., so I've ordered an HB Industries spring kit and will do a trigger job. Maybe it's my small hands but the safety lever seems fine to me, as does the grip.

I also ordered from HBI a paddle mag release and extended charging handle, which will go on the right side, since I'm a lefty. I also plan to put a red dot sight on it.

When I ordered the Scorpion I also ordered two Manticore Arms 32-round magazines from Prepper Gun Shop. They arrived the day before the gun.

Today I got it to the range despite the rain. Thankfully, my range has a covered firing line. The crummy weather let me have the place to myself, which was really nice.

A pic of the gun with the factory and Manticore magazines:

First 10 shots at 25 yards:



I moved the rear sight 13 clicks to the right to center the POI. After it was zeroed I used up the rest of the ammo banging steel on our 25 yard plate rack.

All told, I put 180 rounds of CCI 9mm 115 grain FMJ Blazer Brass through the CZ. There were no malfunctions. As a lefty, I find that a lot of straight blowback operated guns will send gun schmutz into my face and the CZ is no exception. It's not bad and something you get used to, but it reinforces the need for eye protection.

The sights are a bit low to come up naturally, and like my stocked Mauser C96, seeing the front sight can sometimes be difficult with 50 year old eyes. The gun will definitely get a red dot sight.

The outside of the faux suppressor got only slightly warm to the touch.

I ordered more of the steel-lipped Manticore magazines. Speaking of which, a Maglula is recommended for them unless you have strong thumbs. I found that once I got to about 22 rounds in them, it became very difficult to load more.  https://amzn.to/2VhcE3a

Overall, I'm very pleased with the Scorpion Micro. It's going to be both a fun shooter and a serious defensive tool.

Beretta Cx4 Storm and Holosun RDS Range Report

 Last week I bought a Holosun HS515C red dot sight to replace the Bushnell TRS-25 that I used to have on my Beretta Cx4 Storm 9mm carbine. The Bushnell is a good budget optic  Today I zeroed it.

Out of the box the sight was very close to being on at 50 yards, with elevation right on and the mean POI about 3 - 4" to the right with 115 grain CCI Blazer Brass 9mm.




A neat touch with the sight is that the turret caps are actually adjustment tools. The little ridge on them is sized the same as the screwdriver slots on the actual adjustment knobs. This is a brilliant idea, IMO.

Top of the sight showing the screwdriver built into the caps, and the solar cell:




Accuracy at 50 yards was OK but nothing to crow about. Here's a 10 shot target fired from the bench. As you can see I yanked one low. The Storm's trigger is worse than I'd remembered. I am definitely going to try doing a trigger job on it.





I also shot a bit offhand but the target definitely isn't worth sharing. ;) The gun is so light with a neutral balance that offhand shooting is a challenge.

I put a total of 100 rounds through the gun today and as expected, it ran perfectly. However, when I went to clean the gun after I was finished I noticed that the rail was a bit loose. It'll be Loctited and then I'll recheck the zero.

Running Ball

(In this post, I used the word "balls" a lot. Huh, huh.)

This past weekend I'd planned to shoot my Rogers & Spencer percussion revolver but couldn't. When getting my shooting gear together, I found that I had only two .454 balls left. I wound up shooting my Pedersoli Brown Bess and Polymer 80 Not-A-Glock, which I'll write up in a separate post.

Something I've preached about on my blogs has been bullet casting for self sufficiency, resistance to government guns bans, and panics induced by fear of them. I recently picked up Lee molds for .454 and .490 balls, and a Lyman cast iron lead pot. This weekend I ordered a Lee .690 ball mold for use in the Brown Bess and my Euroarms Magnum Cape Gun.

I took a long weekend to decompress from bullshit at work, so with today's weather being decent I setup one of my Coleman stoves out in my shop to run some .454 balls.

Here I have the mold warming while the lead pot comes up to temp. The foil trays are for me to dump the sprues and dross when I flux.





It took awhile for the pot to come up to temperature. I'm finding that keeping a good constant casting temp is an acquired skill that I've yet to master. My balls were coming out either wrinkled or frosted. Wrinkly balls mean that the cast was too cold while frosty balls are a sign that it's too hot. I put the wrinkliest balls back into the pot but I'm keeping some that aren't too bad. These will be fired at a maximum of 25 yards at targets the size of a paper plate or larger, so minor imperfections won't be an issue.

I haven't counted yet, but I should have at least 50 shooters here. I called it quits when I ran out of gas in the stove.




Aside from the Rogers & Spencer, these will also work in my 1858 Remingtons. One could load them into .45 Colt cartridges, as well.

It is possible to keep even percussion guns going without buying factory supplies. Aside from casting your own bullets, it's possible to make black powder and even percussion caps at home. The latter especially is potentially extremely dangerous, so proceed with caution. My plan to deal with future shortages is to stock up ahead of time.

Edit: I wound up with 97 shootable balls from my first batch. After the stove cooled and I was able to refuel it, I ran another batch and came out with another 126 usable balls. That's a decent run and will last me awhile.

Tap and Die Sets

In my quest for self reliance, one category of things I've tried to acquire has been a variety of tools. On the top end are my mini-mill and mini-lathe. Tonight I used something a little further down the scale, a set of taps and dies. I have this inexpensive SAE and Metric set from Harbor Freight.

Yesterday when I shot my Pedersoli Brown Bess carbine for the first time, I wanted to use the ramrod for cleaning. One end has male M8-0.5 threads. However, I found that although I was able to thread on my worm, I could not thread on the adapter (part number SA-10-BESS) that allows me to use regular 10-32 rod tips, like a cleaning jag. So, I had to bring a separate range rod.

After work tonight I gathered up the ramrod, worm, and adapter and went out to my workshop. I first chased the threads in the coupler with an M5-0.8 tap and tried to thread it on the rod. No dice. Then I chased the threads on the rod itself with a die. That fixed the problem.

The total elapsed time was about ten minutes.

Think about how many threaded fasteners and parts you have in your life. A tap and die set may not get used frequently, but when threads on something get damaged, having such a set can allow you to fix it quickly.

The Original Real Man's Coffee Cup





It is a USGI canteen cup made by Ingersoll Products sometime in the early 1970s. I got in around 1985 after I joined Civil Air Patrol. The outside is black from heating many meals in campfires.

American servicemen have been using canteen cups since the introduction of the M-1910 over a century ago. It's one of the best pieces of gear ever. The main thing it really needs is some kind of a lid. I have an older Heavy Cover brand stainless steel lid that I modified a bit to make it lighter, but for a couple decades I just relied on a piece of aluminum foil.

Newer USGI canteen cups have folding butterfly-style wire handles. I prefer the older L-style cups like this one. It's one feature of the Keith Titanium set that I would change. (OTH, the Keith sets come with a nice lid for the cup, so there's that.)

The horizontal slot in the handle is to allow you to put a fork from the M-1926 fork into it as an extension for when you're cooking on a fire. The vertical slot is to allow it to be slipped over the handle of the mess kit (AKA "meat can") so the whole ensemble can be dunked in boiling water for field sterilization.

Survival Resources has a nice article on useful mods to this style cup, including how to make a lid, adding D-rings to the handle so you can use a stick for an extension, and adding a bail. Check it out. (Incidentally, I recently ordered a few things from Survival Resources including a haversack. I plan to do a post and/or video on that as soon as I can get to it. No problems at all with my order and I got it quickly.)

Townsends: Fire Starting: No Matches, No Lighter (Video)

This is a very good video on fire starting with flint and steel, including the use of a flintlock, from Jas. Townsend's & Son's YouTube channel:




Aside from a flint and steel, they demonstrate how you can do it with a flintlock gun.
