10 rounds are better than 5 I got it.![]()
ar15 magazines are plentiful, and faster reloading - possibly.Just got a couple of questions...
Why is there a need for this?
What is wrong with the stock mag's?
guys, please clear this one for me. Is it possible to use XCR 7.62 magz with this adapter.
as longest you got the rifle within the last 2 years, u should be ok on the 5.56 models
Sure, the mags will fit just like any AR mag.
The larger questions are:
1) Will the adapter, designed for the current 5.56 CSA's, work in the 7.62 guns.
2) If so, how extensively do you have to mod the adapter or the receiver?
The 5.56 mag well is not the same size as the 7.62. North Sylva's info sheet says the adapter won't drop-in to the early model 5.56's without receiver mods.
Don't expect to buy an adapter, drop it into your 7.62, and head out to the range.
I have CSA in 7.62, so I guess it will not work then. Would love to use AR15 style magz on cz
I'm going to see if I can make one fit. It's worth taking a look at.

Although I'm waiting for one of the dealers to chime in and confirm whether or not these adapters will fit in the 7.62x39 rifles I did come across this picture on a Czech site that I have ordered a few specialized parts from.

By the looks of it, the appear to fit in 7.62x39 rifles unless the took a .223 rifle and shoved a 7.62 mag in it.

Interesting dust cover, where did you get it and will it fit the 858?
From the pics on the website the other side of the dust cover has a locking lever on it which I presume is to tighten it to the receiver to minimize (maybe even eliminate?) loss of zero. From what I've seen of them they look quite robust. I would hazard to guess that they would be on par with a NEA top handguard rail for holding zero.
PS: Still hoping a dealer can confirm whether or not those adapters will fit the 7.62x39 rifles![]()
Hello,
All parts are fit for CZ858 Tactical.
