3 came into the LGS. One came home with me. Design is very similar to the Scorpion receiver, blowback design. Shipped with 300 Blackout labeled mags. Standard AR magwell-so it accepts magpul or generic AR mags. Magwell is part of the trigger housing = polymer with metal lined. Has the standard front and back pins to attach the upper to the lower. Remove the front pin to drop the trigger housing out. Polymer trigger housing. The receiver is the serialized part.
The Bren is not blowback, it's gas piston. My mags are marked 5.56 and 300. They are a CZ branded mag very similar to a PMAG and with a window in the backstrap.
My Bren arrived yesterday. It comes with two of the above mags and a little zippered pouch that includes a cleaning kit, gas regulator adjustment tool, wrench for removing the handguard, and front sight tool. The cleaning kit is a nice touch. I took it out of the box, put on an SBA3, and that's basically all I had time to do. I took it to my agency's range yesterday, but only had time to shoot 20 rounds while the participants were on lunch. I shot five rounds to verify function and then ran a VTAC 1-5 drill in 3.19 seconds, which is a reasonable time but my bests are usually more like 2.75.
I put a couple hundred rounds through it today. My overall impression is favorable. It's a very soft shooting gun coming from 11.5" ARs. The trigger is longer, but light and reminds me in feel of some AK triggers. The controls are simple and intuitive. I like the bolt catch and release inside the trigger guard. The action feels very smooth. Maybe not B&T smooth, but close. The factory sights are basically a Troy knockoff. The front sight has a white dot and is made up of two wheels so you adjust the elevation and then can independently turn the post without adjusting elevation to get the dot facing the right way. The rear sight apertures do not lock in very positively. I like the 45 degree selector, but the levers are plastic and I don't care for them. They have some give and just don't seem very nice. They remind me of the plastic safety on recent Daniel Defense guns.
I have some concerns that heat buildup will be a problem. The handguard is basically attached to the trunion and gas block via screws and the whole thing acts as a heat sink. After about 50 rounds in a couple minutes (but not mag dumps), the handguard was too hot to hold. Shooting a 30 round qualification course over about 5 minutes did not cause the gun to be too hot to hold, but it was getting there. The modular nature of the gun likely means aftermarket handguards are coming. Perhaps something free-floating will help.
I did not do any real accuracy testing other than zeroing. The gun groups fine for that purpose and reliably hits 12"ish steel at 100 yards. My zero probably needs some refining due to the untraditional front sight post. That style is never as easy to adjust as you would like. I have not put an optic on it yet, but will. My immediate plan is to register it as an SBR and put an ACR stock on it with a Dan Haga Design adapter.
I'm hoping to shoot the gun some more this week.
