CZ 527 in 6 MM ARC discussion starter
« on: February 05, 2021, 06:36:03 PM »
Looking for a CZ 527 in 6mm ARC. I have wanted a fast twist 6mm PPC PPC type cartridge for a long while now. Seems like in the next 5 years a Factory 527 in 6mm ARC would be more than doable. If I am not that patient would anyone here know of a group buy for a drop in 6MM ARC barrel in 6MM ARC?


Came across one in 6 Grendel variant a few years b4 CZ offered the Factory Grendel. I am happy with the Grendel to say the least. Just think the ARC may be a bit more recoil friendly for a youth gun or just someone who desires less recoil from a light weight mini action rifle.


No hurry I suppose as Brass & or ammo is currently in tight supply like nearly everything else.

Perhaps my best option will be a re-barrel. Seeing some indicators that CZ may be discontinuing a lot of rifles including the 527. Can anyone confirm or deny the discontinuation of the 527?

Think Ill order a drop in barrel from Pacnor & then Ill have at least 5 months to find components to reload. The components I namely brass Expect difficulty.

Brass is the only item I really do not have.

So what do you want to bet, CZ has at least 1 prototype 6 ARC out there being tested prior to releasing a new 527 chambering to market? My gut says 2021 is a prototype year for CZ on the 6 ARC just to insure there are no worries prior to releasing to market.


Well before summers end, Ill have a personal  prototype any way, thanks to the help of Pac-nor barrels.

Received The 22" 1 in 7.5 T Pacnor barrel A couple months ago. Still loving it. Think they call this a fast barrel. Finding all max listed loads need to be backed off a little more than 1 grain to achieve same velocities. What I really like about this barrel so far is the easy clean up & the lower recoil compared to the 6.5 Grendel

Options for brass Have included Purchasing factory ammo. Also have fire formed Lapua 220 Russian & trimmed to length. Others are forming 6.5 Grendel to 6mm arc. Forming 7.62 x39 is another option that can be done though I feel there are much better small rifle options. options


Really liking the 6mm Arc in this CZ 527 platform. Not liking Factory ammo so much as the longer OAL is a fair bit more difficult to load the magazine. For hunting purposes I expect 100 grain bullets & less will be preferred in this platform based on my experience.


Unless a guy wishes to have the option of lighter 65 & 70 grain bullets I can't go very far to encourage others to go this rout vs the 6.5 Grendel. ARC may be a better Varmint gun though there are many lighter options to cover that task. Still somehow I really do like it, suppose I am liking the somewhat lesser felt recoil & flatter trajectory. well see in a year or so when the newness wears off.
