[ARCHIVED THREAD] - CZ Bren 2 556 accuracy

Posted: 10/23/2020 8:50:56 PM EDT

Pretty new here though I've been on other forums for a long time. I'm still learning this place and was told to post here. I've skimmed the main CZ Bren post but it seems to mostly be about x39 issues.

I've had accuracy issues with my 11" 5.56. I'm just curious how others are doing. The only one I've even heard of shooting decent is the one Cowan/Sage Dynamics reviews. That's the accuracy I would have expected from the platform but mine is no where near that.

I've asked on the CZ Bren FB group with only one response and SH forums, also only one response. Surely some folks here have experience?

Regards,
Dan

What kind of accuracy are you getting with what ammo?

Welcome to the forum!

I had the Bren 2 5.56 Carbine but sold that one and later got the Bren 2 5.56 14" (pinned to rifle).
I got the 14" b/c the carbine had terrible accuracy, about 4-5MOA 10rd groups using different types of ammo.

The 14" Bren 2 is about 2.25-2.5MOA (10rd groups) using Geco 223 55gr FMJ.
Haven't tried much of other ammo, but IIRC the ones I did try are around 3MOA if non-match grade.

My friend's 11" Bren 2 also in 5.56 is around 3MOA using the same Geco 223 55gr FMJ.

Dan,

Likely Sage Dynamics is the exception and not the rule. Reviewing even the very early public testing data back in 2016, CZ engineers were only achieving around 2-3 MOA with S&B brass.

Compare this to an off-the-shelf Geissele SD (DI AR-15 around the same price), the guys on Snipers Hide are getting 0.5 MOA with 77gr OTM.

What kind of accuracy issues have you experienced?

I don't remember what I shot initially when I got the gun. I switched to a 7.8" HBI hand guard, and later the 10.8 when it came out. When I took the 7.8 off I noticed my gas block was touching inside but didn't think much of it.

I'm shooting a generic hand load of 75 bthp that groups less than 1.5 moa in every gun I own. I've made a 10 shot .5" group with it out of a bolt gun. I've also tried some lighter weight factory ammo with worse results. I never would have thought this would be more than a 2 moa gun. Seems to not be a problem for most folks but I expected a little better.

I have had good accuracy on my 11” 556. I got a group under 2 inches with match ammo. M193 around 2-3 inches. That’s plenty satisfactory as far as I’m concerned for it’s intended purposes. The ergos and operation are great.

This platform is not a precision rifle platform. Expecting .5 -1.5 moa with your hand loads is asking way too much out of it.
Im not saying that 6-8 moa should be expected either tho, if you have screws touching the barrel/gas system that is definitely something to rectify.
However this platform, imo, is intended to be an intermediate cartridge battle rifle, accuracy expectations should reflect that.

I don't think expecting 1.5 MOA with handloads is asking too much at all. Hell, my Galil ACE 7.62 NATO does 1.2" 5 shot groups with handloads.

I have a NIB Bren 2 carbine that I'm thinking about selling due to accuracy reports. It seems these are 3-4 MOA at best. If that's the case, I'd rather sell it unfired at a premium and buy something else.

Does anyone have a Bren 2 carbine that shoots 2 MOA or less?

The gas block bonking anything isn't conducive to precision shooting. I would certainly check for no contact between the two if possible.

So I got bored today and decided to take the Bren 2 carbine to the range. With 75 gr Hornady and 77 Nosler custom competition reloads, I was getting 1" 5 shot groups at 50 yards. This was wth a 2 MOA red dot. I bet when I thow a 1-6 optic on it, it'll shoot 1.5 MOA. Not bad, but not great.
