Lilja 1.00" X 21" CZ 457 22LR barrel Question

[p5200]

Hello everyone, Does anyone know if this barrel comes with a set of shims included? https://riflebarrels.com/shop/drop-in-barrels/cz-455/22-rf/cz-455-457-22lr-1-000-x-21/

Prob better to reach out to Lijia directly to confirm but when I ordered one directly from them it did.

I believe this one, is directly from them also. This barrel should just drop in unless shims are needed correct? I will have to relieve the stock some.

 

[TubbyT223]

Shims will be needed for sure Lilja cuts theirs tenon longer it seems. They have a video on their site on how to measure or you can ship them your action and they can measure it.

OK, so the headspace will be tight and will require shims to increase it slightly? This is my first time doing this just want to make sure I fully understand things.

All CZ barrels from Lilja come with barrel shims. The 1.00 diameter will require some barrel channel work...if you didn't order it yet the 21x.900 fits a varmint or mtr stock without modification.

 

[TubbyT223]

Yes HS will be tight. I just tried without a shim and the bolt wouldn’t even close. Can’t remember what was used but maybe it was the .004 or .005. It was tight

I haven't ordered it yet but, I think the size you mentioned are out of stock. I'll call and order and ask to make sure.

FYI AREA 419s barrels are meant to install with no shims. They also have a different chamber. They are made by Liljia to Area 419 specs. That might be a good option as well if you are just wanting accuracy and not weight for say PRS

Just placed order for the 1.00" X 21" Lilja 22LR. Any suggestions on what to use to relieve the CZ 457 Varmint stock with? I have some sand paper. Is a socket good to do the sanding with? I free floated my Weatherby Vanguard a while back Seems I remember using a socket for that. I guess I need to seal it after sanding? Thanks!

My last two Lilja’s took .005 for Lapua. For Eley it took .002. That should give you a start.

Saw this on Lilja site. ( The receiver stock screws are a T-27 Torx Head ) the action screws on my stock are T25 Torx? I think they are talking about thr barrel screws I misread.

There’s the right way and the way I would do it. I would use a socket and sand paper

Any suggestions on a depth gauge that's not real expensive but, usable for this job? I've got a good Mitutoyo Digital caliper but, I don't know if it would work for this or not?

 

[bobby1028]

A socket or proper size wooden dowel wrapped with sandpaper will do very nicely, sealing or 2 coats of an outdoor spray paint or primer will suffice. Digital caliper is tough to hold squarely against the action face or barrel tenon which can result in a .002 to .005 error. Google Igage, a measuring tool company, they make a cheap T square adapter to attach to the calipers which will give you the proper measurement. Headspace you can vary depending an ammo type. Exclusively Eley you can try .039, Lapua or SK .042. FWIW I've experimented with a number of different barrels and settled on .042...I can reliably feed, extract any brand, and haven't seen a loss of accuracy or increased ES or SD from Eley running the increased headspace. Take your time and have fun.

 

[p5200]

I'll look for that adapter Thanks! I'll try .042 also

 

[p5200]

I got one of these I think it should work pretty well with my Mitutoyo Calipers.

You can use fealer gauges if you remove the mag well

I remember seeing that on another forum but wasn't sure about it but, thanks for confirming that. I'll measure using both methods.
