CZ527 Critical Dimensions

[adamjp]

OK, got asked a question today and don't know the answer.

With the CZ527;
* distance between action screws?
* distance from rear action screw to front of trigger?
* distance from rear action screw to back of magazine?
* length of magazine well?

Someone is doing an inlet. Unfortunately I cannot help Adam.

Not an inlet...but exercising a wild idea.

Front of trigger shoe or entire trigger unit ? Will an aftermarket trigger do ?

Adam's relaying my question. I have a LH Zastava M85 action I bought a couple of weeks ago to build a little light mag fed 20 practical or 6x45. I'm wondering now about adapting a 527 trigger guard and mag but unsure of the dimensions.

The original plan was 10 round Pmags but they won't fit into the action without a lot of modifications to both the mag and action. I can probably get it to work with shortened/slimmed down AI 223 mags but it's a lot of work.

Either would be fine. As Greg has explained, we are just trying to understand the dimensional differences.

This will get you close.

CZ 527 - 223

Hope it is accurate enough. My automatic visual ruler only measures to nearest mm where as GregT seems to work in .00000000000000000000000000000000000000000000000001mm

Cheers Bruce, that's well and truly close enough for what I need to check, thanks a lot!

I actuallly spend some time this arvo and milled down the top of an AICS 10 round plastic mag. It is surprisingly close to fitting with not a lot of work. I was going to make a trigger guard to suit but it might end up in a very minimalist chassis stock given it's probably less work than making a trigger guard.

This is a bit of a mutt of a rifle I'm putting together. I went to a competition the other week and did really well from 800m thru 600m with the 6.5 SAUM but it was a bit heavy and awkward for the last 30 rounds from 75m thru 25m offhand. One string was 5x 6 second exposures with 2 shots each exposure, it was a bit of a hassle without a 10 round mag. I figured a 223 based 10 round mag fed very light rifle was the go so this will be a little carbine style rifle for that sort of stuff as well as bunnys etc.

Sounds like an interesting comp.
