If i understand correctly they threaded so that the minor diameter is same as factory prefit !? That is definely something new
No need for parallel bore on the receiver like with shrink fit barrels

Great news. Shared info much appreciated
I thought that I had read that Kenny guarantees his rifles to shoot .3’s at 50yds for 5 shot groups, so threaded action mated to the barrel must have potential.
Love the versatility of this platform.
Cheers!
I’ll answer my own question since they finally got back to me. For anyone who’s interested, the La Chassis can fit 1.25” barrel diameter. I’ll let everyone know for sure once I get my build done.
Can anyone confirm CZ 457 Model # 02326 (https://cz-usa.com/product/cz-457-manners-mtr/) has t-nuts installed to add an area 419 Arca rail?
Does anyone have better details on how to install a "Silent Thunder Ordnance" mag well in a 455/457 KRG Bravo?
No instructions came with the mag well, no return email from the company. Web site just says:
"Installation is as simple as inserting the rear "hook" area under the front end of the trigger guard and then rotating the front of the magazine well downward. This is typically a snug friction fit, so while on our sample no adjustment was necessary, in some cases minor fitment +/- may be necessary."
The part is so wide at the hooks, no way it fits under the trigger guard. What am I missing?
Thanks

Just a rubber "ball" that I had lying around. Just to try it out. Might change it later, but so far it works all right.
CZ 457 Varmint 20" in a Krg Bravo back bone with a W3 folder and enclosed forend.That is insanely awesome! You know we need more details
Area 419 30 MOA rail for a Spuhr with additionally 20 MOA cant for a total of 50 MOA which is a tad less than half of the total adjustability of the IOR Recon 4-28×.
Old random bolt knob rubber ball, a Atlas PRS bipod and a Ase Utra ECOi moderator.
@502Chevelle can you confirm which arca rail you have on the manners? Ordered mine today, won't be in for a week.
Shooting friend of mine just got the same rifle in and installed an Area 419 Universal Weight-Tunable rail on. The Manners already had 3 t nuts installed.
thanks, I think thats the direction I'm going. Still thinking about the weighted rail tunable one though
A friend of my was looking for more weight up front for a Bravo based CZ457 he uses for Rimfire PRS. I roughed up an extra heavy spigot for him. A little ugly in its rough state but he is loving the new balance point. Comes in right around 4.5 pounds if I recall correct.

Thanks! I’m looking at options for a rig for my son to shoot matches with me. I wish CZ sold just barreled actions. Action screws supported only by wood isn’t something I want to mess with.
Even the pillars that are in the MTR stock are soft. If you want the best performance out of your 457 you need to pillar bed it.
Thanks! I’m thinking of going with an HB Industries chassis, like they used to offer on the now-discontinued varmint precision chassis rifle. The problem is, after getting the chassis set up like I want and whatever cz 457 I can find, you’re into B-14R money. BUT, it’s easier to add weight to a chassis, for balance, than it is to add weight to the hmr stock to that comes on a B-14R.
You do know that you can buy B14R barrelled actions don't you? The standard 18" steel ia about $650 and the 20" MTU SS is $1100. Then you can put in chassis of your choice.
Honestly I didn’t even think of that, mainly because I couldn’t find a barreled action and purchased the complete rifle for myself last year.
You can always sell the HMR stock, lots of people looking for one. The usually sell for $325-350 from what I have seen. There is a guy looking for one now on one of the forums.
Oh man, my rifle is in a BA Comp now, and I just sold my HMR stock in here for $275, lol. Without derailing the thread further, I think a B-14R in an XLR chassis would be a good fit for my son.
Hope to have my new 457 MDT ACC next week!
What are you PRS/NRL guys using for magazines and magazine holders? I know some COF require a mag change and I’d rather not be fumbling in my pocket.

I've been using a SAP AICS mag pouch with a 3D printed insert that fits CZ mags, but now that I have couplers available, I can have a spare on the gun at the ready and do mandatory mag changes in only a few seconds.
Aluminum couplers are back from hard anodizing and ready to ship! PM me if you’re interested! $50 for the aluminum version, $15 for 3D printed, free US shipping. 100% Minnesota made.
I got to give them a good test a 2 day NRL-X and a few regular matches with no issues. I’ll have them at NRL22 Nationals as well - there might even be one going with a prize gun

ACC Gen 2. Definitely going to wait for the CZ version.
I picked up a mag coupler from @1911Shootist . It is well made and the transaction was quick and smooth. I haven’t put it together and run it yet, as I just got home from the beach last night, but so far it looks like a winner.
So here is the @1911Shootist assembly mounted up and installed on a vpt. Fits good with about 1/8" of clearance between the stock and mag body. Haven't had a chance to run it yet, but so far looks good. The top of the mag is below receiver height and it is level with the stock, so I don't see it interfering with ejection. Also a good view of the Area 419 barricade stop for USMC22.
Grabbed one of the Area 419 CZ MTR Packages the last go around.
Got the Manners MTR Sitting waiting for the Gen II Razor on Monday.

Thanks! I’ve got the manners mtr with the adjustable cheek piece and length of pull waiting on the scope. Area 419 sold out of their mtr’s quick! Not sure how often they get them but they go quick.
following up with a pic after I got the arca rail, bolt knob and harris bipod conversion in. I didn't spring for the RRS SC-ARC on this one. The area 419 version is as good for what it needs to be on this anyways.
Not sure if I ever posted my original Manners 457 after @jducos did some work on it. KMW Loggerhead and Sykes rail added. He did a fantastic job!
Finally got the La Chassis in after 2 weeks. I currently don’t have the action to drop in since it’s at MCR. Initial impressions just handling it seems well built. It’s not substantial like an ACC but appears to be solid enough. As pictured it’s exactly 2 lbs 14 oz on my scale. A member on RFC said the forend was flexy but manipulating it by hand so far doesn’t appear so. Again I’ll have to wait until I get the barreled action in to verify.
Grey Birch said that the chassis can fit 1.25” barrel but I’m going to send it to MCR so he can verify himself and modify if needed.
Does anyone know where you can get replacement magazine springs for the CZ457 10 Round 22 LR Mags?
No, but if you finds a place that sells replacement parts for them, let us know. I could use a couple pieces parts.
the detent spring and detent piece that hold the mags on are available from Diversified Innovative Products if you need those.
That little spring and plunger can be slippery and trying to pull the great escape.
