@Wingman has this got the compound throat or the standard 1.5 deg type? I see the bullets are loaded fairly well out of the case which make me think its the GII chambering.

Im not to sure as I didnt chamber this one, pretty sure it was a custom odered reamer with a shorter throat to suit the CZ 527s mag length and 123gr A-Max's. Loaded to max mag length of 2.320" (COAL) gives the A-Max and Scenars a 10-15 thou jumpQuote:

All well and good at shorter ranges but the bullet design being lighter and longer in the front doesnt do as well at longer ranges as it slows down.
A good test when deciding on a bullet is to load some at 1200 to 1300fps and try shoot a group at 100y.. you will find the Lapua with its tangent ogive and more centered center of gravity will always group best.
I did these tests with my 6.5 Creedmore and a range of bullets.. the 143gr ELDX which shoots under 1/2 moa at 2900 mv in my rifle was unstable even with the 1-8" twist at 1200fps entering the paper sideways at 100y.
The Lapua 139gr scenar and 130ge Sierra TMK shot as well as they do at 2900fps and the 136gr Lapua with its hybrid ogive also showed unstable keyholes and wild groups.
In working terms, eg when used for long range hunting, a bullet that is stable at the transition to sub velocities is always going to fly straighter in the higher (usable hunting) velocities too.
Id put money on the ones that hit the paper sideways will have a wobble even before dropping to subsonic velocities.
Give me a traditional tangent any day over the recent "fad" of low drag hunting/match bullets.
How do you know on the Aliexpress site if its SFP or not ? I cant see it stated. I have a 6.5 grendel AR, looking to shoot 300 - 1000yrds
How does the handguard/forend attach to the barrel?

Great stuff. I love my 6.5 Grendel AR15 upper.
All the Marksman range are SFP.Quote:

How do you like the precision in the cz527 build? I was recommended to get myself a rem700 instead. For a 6,5 grendel build...

I love your work, I'm currently working on something similar for a .223 Howa mini so I can burn my stash of .223
I am planning to make something very similar to your chassis and like the simplicity of it.
How does the pistol grip attach?
I love the micro mauser cz actions. A Rem 700 would need a custom bolt face for a grendel and a sako or ar15 extractor fitted. There's no mag that would feed the grendel case in the Rem 700 unless you modded a howa 7.62x39 follower to fit. Could be done but its a lot of pissing about.Quote:

Yes. The thing is that my gunsmith recommended that i get myself a rem700 instead. Something about the action is more sturdy. How would you say that the precision is on your build? Was thinking about the same caliber and about 48cm barrel.Quote:

No more sturdy than a Howa mini in grendel.
How would you rate my CZs precision with 1/4 moa 5 shot groups at 100yds?

Very nice[emoji3] how long distances have you shot?Quote:

My pet load gives 2450fps with the 123gr Lapua scenars.
I haven't had the opportunity to stretch its legs much past 200 meters. I tend to grab the 6.5 Creedmoor or 6.5x47 Lapua for the longer shots.
Finally got to stretch the little Grendels legs and test accuracy on a rock at 500m a couple of weeks ago with @Flyblown.
Even with a tricky little wind we managed to land 3 rounds each on the same spot.
Such a fun and accurate little lightweight rifle. I really should use it more.

Well done mate...enjoyed that read......low recoil,but what about the front end noise???...hopefully that “can” doesn’t reduce its accuracy
Its not too bad noise wise when suppressed. The BM8208 is quite a fast burning powder and only needs the 14.5" of tube to get max velocity with the 123gr and a full burn.. no big muzzle flash like a 7.62x39.
Its much softer and quieter to shoot than my 6.5 Creedmoor with a fill burn loading of RL16 and a 147gr ELDX with a 19.5" barrel fitted with a DPT suppressor if that is a worthy comparison?
Bloody good I reckon if your pushing it out 500 yds..... sweet
Fairly decent energy retention at 500m too. About the same as a .243win with a 100gr projectile we worked out.

Hey Mate i'm still trying to figure out how you did this (Huge fan by the way) don't the AR rifles have a barrel thread that the bush screws onto and locks the barrel replacing the old barrel nut?Quote:

Or is the handguard bush clamped to the barrel then guard threaded on to the desired position then clamped?

Picture speaks 1000 words :thumbsup::cool:
So that’s 3000:)
I know this is rather an oldish thread but well done!
Great write ups and a well thought out project.
Have you got to take many animals with this?
Also how noisy is it in the bush? With the likes of bush scrub and tingy sounds coming off the metal parts?
Thanks mate,Quote:

Noise wise Ive not noticed it being any different to a std format rifle. The suppressor has a neoprene sleeve and I sling it through the tight shit, its quite short and easy to handle so hasnt really been an issue.
Nice! Thanks for the reply.:)
Wow still supersonic (just) at 950m.Quote:
