How does the impulse feel compared to other AR PCCs you have shot?
Locktite might help the castle nut but you can try some plumbing thread tape if not. There's even black dope tape now.

About the only downside on a shortstroked rifle is that you'll have one more crevice for all that blowback-action-crud to accumulate in.

The CE Pro Chrono Digital is the best deal for casual Chrono use. You can catch them on sale for $100 or so. Accurate, reliable, and sends numbers right to your phone via Bluetooth.

Unless you are shooting a very light hand load below 125 PF (pf out of a pistol) then the comp will likely do at least something with the gas available. I confirmed this with my own testing and you can too easily enough as someone above suggested. But the work the comp is doing may not be worth the increased weight on the end of the barrel, which will slow your transitions. That was the determination I made, but its an individual preference. The greatest improvements in flatness I have found for PCC have been in getting the bolt and buffer system right and using a fairly light load.

2 or 3 days a week generally.

I also don't see how it could be weight. My 1-6x24 Razor is 25 ounces, the new model is I think 22 oz. If they made a version of the new lighter one that was 1-6x32 but that took it back up to 25 ounces that is the one I would choose. I think others would too.
-
That all makes sense, but still begs the question, why not have a
1-6x32? Am I missing something?
-
This has also been a mystery to me. Every 2-7 scope has at least a 32mm obj, so I assumed it had to do with improving the 1x aspect.

I have been waiting for a good deal on a used SP01 to come up so I can convert to SAO and do a grip reduction to fit my wifes weird midget hands. After a year of nothing remotely dealish I am coming to terms with buying new.
-
I believe the 3 that come with it are 16, 13, and 11. The shortest one with tightest coils is 16. The longest one is 13. The shorter one that has the same coil spacing as the longest one is the 11.
-
That's good insight. The biggest improvement I found was realized when I lightened my load and bolt simultaneously. I viewed this experiment more as helping someone who already owned the Taccom decide whether to spring for the new short stroke unit.
Now with PCC and 2x4 in 3 gun it will be interesting to see builds developed specifically for that game.
-
I don't have a blitzkrieg to compare, but if someone wants to mail me one for a week I will test it out side by side and mail it back haha.

I have had the Taccom 3 piece buffer in my PCC for a year or so but saw their "Short stroke upgrade" a few weeks ago when I was buying another shell caddy from their site. $20 for a spring and a piece of plastic seemed a bit steep, but I just can't help tinkering so figured I'd give it a shot since I was already paying $5 for shipping the caddy. I did a side by side comparison with their standard buffer system components, which had already shown a marked improvement in my gun.
My last USPSA match with this PCC was 139 alphas, 18 charlies, 1 delta, and 3 mikes. So fast double tap hits are not the problem for me, but like I said...tinkering. The mikes were all from a weak side stage, which is a weakness of mine, along with moving too slowly. I should have spent this time sprinting around, but messing with components is way funner.
The rifle is built mostly from New Frontier parts. Side charging, 16" barrel, and the discontinued Hiperfire 3G trigger. I am not using a comp as I found the stability increase was not worth the transitions increase for me, especially in steel challenge. Overall weight is right at 7lbs, the bolt total weight is 14.65 ounces. I am using a standard carbine spring with the Taccom buffer as it shot flatter than the reduced rate rifle spring that shipped with it originally.
My load is pretty light, it shoots 138 pf out of the 16" barrel. I think the light load played a part in the results I obtained.
I shot a string of double taps at 20 yards with the standard Taccom buffer system then added the short stroke upgrade and repeated. Bolt hold open no longer functioned, of course. The Short stroke kit looks to take about half an inch off of travel, but I suspect the wave spring plays as big a part as the reduced travel, at least with this light load.
My split times with this setup are pretty consistently right around .18 and I tried to keep them steady across the test, using a timer to confirm. I also tried to grip the rifle with consistent medium pressure for each string.
The short stroke kit absolutely shot flatter and allowed the dot to settle faster producing a tighter and more consistent group. The impulse smoothed out considerably. I suspect the wide shots on the Long Stroke targets were from splits pushing below .18 a bit, though I didn't get super scientific with this. The down 3 hit on the long target was from the first pair and I'd call it a user error flyer.
With the short stroke kit the dot just sat there. It was a noticeable improvement and absolutely worth $20 at least with my set up and load and purpose.

The BCM grips are pretty vertical and come in different sizes. The Mod 3 is the largest I believe, no idea if it's large enough for you though.
-
All of those should work fine for matches. The only one on the list I have owned is the CMC. It is ok. I use it on my .22 training rifle and run Hiperfire FCGs on most everything else. I bought a bunch of the 24 3G units with the curved trigger for half price when they were discontinuing it in favor of flat bow model. They are great and I wish I had bought more haha.
That being said, you aren't likely to notice tiny differences in trigger pull in the middle of a match. Split times will be about the same.

Whelp, I stepped outside to my home range today and tried out my DIY *thumb rest. Turns out that it effects my grip negatively causing the TSO to exhibit more muzzle flip. Using the stock thumbrest with my support thumb pushing down on top of the rest and wrist twisted forward results in a very flat shooting pistol. Not so much with my home made rest.
I reckon I will make another with less angle to it. Sometime.

Cool, thanks. Didn't think of that.
And if you're worried about permanently modifying the gun, you can just superglue a piece of black pencil eraser that will take out most of the over travel onto the back of the trigger guard.

Does anyone know what sort of trigger work can be done to the 1301? I'd like to tinker with mine a little, but I'm not really sure where to start.
One easy thing to do yourself is To add an over travel adjustment. You can carefully drill a hole in the rear of the trigger guard and thread in a set screw.

Sell them.
I want one.
Sent from my iPhone using Tapatalk ProI have learned my lesson regarding turning a hobby into a job. It was easy to make this, just give it a shot! I also think thumbrests are best customized to the individual shooter.
As far as using forward serrations, if that is something a man is committed to he's best to avoid most thumb rests. CZ makes that low rest that would allow better forward slide grip, but it does not look conducive to a high grip.

Another rainy Saturday here in Georgia, and not having enough in-process projects *cough*, I decided to make a new thumbrest for my TSO. The stock thumbrest honestly doesn't bother me that much, though everyone seems to complain about it. I have a very high grip and with the stock rest my thumb just pushes down on the very top which works okay. I just figured I could do a little better.
I made this unit out of some angle aluminum scrap. Sawed, filed, ground, drilled, etc until it fit the gun, my grip, and my holster. Then I sanded it to 600 grit. I first tried blacking it with Aluminum Black and then sanding that back to give it an aged patina look, but my wife claimed that looked pretty dumb. So I painted it with the only black spray paint I had around, which happened to be textured. Hey, I can always sand it off later!
Its definitely an improvement in function, I'm not gonna make any claims in the looks department.

So, is it essentially the waffle-checkered frame that they have discontinued? I ask because that's what I have now, and if I were to ever have a open gun in the future, I'd want it to have the exact same frame.

I reckon you are right, I hadn't thought about it like that.

TSO Safety
in CZ
Also, if you are .80 out of holster to first hit I do not feel that I am qualified to advise you and retract my statement.

TSO Safety
in CZ
The CZC extended safety is awesome and the fulcrum on/off it allows is one of my favorite things about my TSO. It might not work with very short thumbs though. Honestly though, I don't feel that the stock safety position is particularly far forward. My wife has weird midget hands and she can work it ok. Could it maybe be your grip?
Edit: sorry you posted that right when I did.

CMMG Customer Service
in Miscellaneous Topics That Do Not Fit in Any Other Forum
Posted
I used the CMMG stainless .22 lr conversion bolt and barrel to build an AR that serves both as a general purpose training rifle and also as my 9yo daughter's main gun. Now, a year later (~8000 rounds), it began to have FTFs every 10 rounds or so. Though it took me a little while to diagnose the problem, it turned out the firing pin had broken inside the bolt and the front of it was protruding though the bolt face on occasion preventing a round from chambering.
I called CMMG and was immediately directed to technical support with no wait time. I explained the issue. He said he'd send me a new firing pin. Didn't ask me how long ago I bought it, how many rounds, what kind of trigger, nothing. Just got my info and said they'd take care of it. A few days later I received a package with not one, but TWO firing pins.
I called expecting to buy a new one, parts break when you use a gun, afterall. CMMG went above and beyond, even though they don't really have much competition in the .22 AR bolt arena. Good stuff.
