Is the magazine well on the lower the same for 5.56x45 and 7.62x39? Will AR15 7.62x39 magazines work in the 7.62x39 Bren 2?

"Sort of" and "Maybe."Originally Posted by Bret
The Bren 2's magwell is designed to accept 7.62x39 magazines the width of AK mags in that caliber. The factory mags have similar external dimensions to Magpul AK mags and, in fact, Magpul AK mags have been successfully modified to function with the Bren 2, though they don't activate the bolt catch when empty.
The 5.56 versions of the Bren 2 use a removable polymer insert in the magwell to choke it down for STANAG mags. It may be possible to use CProducts AR15 7.62x39 mags in the 7.62x39 version of the Bren 2, if the 5.56 magwell insert is fitted. I don't think this has been tried yet.

Couple of thoughts here:
https://www.youtube.com/watch?v=pL75snWpbcQ
The gun is seriously over gassed. The 9 inch 7.62X39 needs a suppressor port bad. I cant even begin to imagine how bad the malfunctions will get with a higher back pressure suppressor. The Sandman K is a relatively low backpressure can so that helps the situation but once I get a chance to try my Resonator K (which I theorize will be a high backpressure can), ill report back.
The clear magazines are indeed garbage. I have a sample size of two and they're both failing at the feed lips. Its a slow death as they haven't outright cracked but they're getting there.
The ACR stock is a piece of over hyped shit. My sample size of one has a cheekpiece that refuses to remain put. Its constantly moving on me and is really uncomfortable. There is also something "off" about the way the gun shoulders. I cannot wait for a chance to change this out for something better. Ideally, the factory stocks are better and someone releases a brace adapter. The fact that it doesnt fold well is also an annoyance. Mine flops around as it cannot latch onto anything (no surprise since it wasn't designed for this gun) and it came without a spring so there's no tension in the hinge.
Aries's summary of the safety was spot on. I find it to be really stiff but not unusable. I have an HBI extended safety on the left side of the gun and the factory on the right. The HBI is too long to be run in an ambi setting as it will grind into my knuckle even more so than the factory safety blade.
I am still trouble shooting my issues with my HBI handguard. Long story short, the bolt started binding over 45 inch lbs of torque on the trunion bolts. I applied loctite 2422, torqued to 45 inch lbs and am running the gun as hard as I can to see if i can get the bolts to back off. I'm crossing my fingers. HBI has been exceptionally responsive to my issues and its been a pleasure dealing with them.
What else to add...
Ah. Zero gas to the face with the Sandman K. I was super pleased with this as my turbo K on my 556 guns, being a high back pressure can, is pretty awful lol. I've had to do a ton of tuning to get those things functional. Short of the actual function issues with the Bren and the Sandman, its a pleasure to shoot. I believe that a smaller gas port should solve the bolt carrier velocity issues.

I appreciate Aries144's report, and while I've fondled the one I want (5.56 pistol) at my local shop, I'm not ready to give up my 805 SP-1 just yet.
Yeah, the 805 is still like carrying a Czechoslovakian tank around your neck, but I've encountered none of the control or mag issues the MS2 is experiencing (at least using PMags). It's a workout program all of its own, but I'm not second-guessing anything about it at the range to date.
I'll be curious to see if they address any of Aries concerns in future runs, as I still wouldn't mind having a lighter PDW.

Has the 5.56 Bren 2MS had issues with pmags?
Senior Member
Mine has not.
Tell my tale to those who ask. Tell it truly; the ill deeds along with the good, and let me be judged accordingly.

The issue with the 5.56 guns is that there is no support for the mag which can result in it being over inserted causing rounds to pop out of the feed lips. The bushmaster ACR had this same issue. The best way to remedy this is to use M3 magazines.

Glad to be of help. I look forward to your evaluation of the Bren 2, should you decide to pick one up.
