Cz Bren 2 Billet lower receiver
Well made well engineered beautiful product Just wished they could come up with a way to use more drop in AR triggers
UPDATE: Due to shortages in factory CZ parts I am making available a "Stripped Lower" option. For this option you will have to transfer over the slide release, slide stop spring pin, slide stop spring, disassembly pin and disassembly pin spring from your factory lower. On the next batch I will have all of these parts manufactured myself to eliminate the need to rely on CZ to make these lowers available.
New for Gen 3: The latest version of the Haga Defense Bren 2 Lower Receiver now has built-in ambidextrous slide release controls, is lighter and includes factory CZ slide release and disassembly pin so that you won't need to transfer any parts over from your factory lower.
Aluminum lower receiver for the CZ Bren 2 that accepts *AR15 triggers, grips, mag releases and selector switches. Will NOT work with all AR triggers. Hammer width must be .25" or wider to dissengadge the Bren 2's firing pin safety. See "Installation Instructions" link below for more info.
SPECIFICATIONS:
Factory CZ Parts Included:
Parts you will need to aquire sepparately:
The Bren 2 lower is not a serialized part and does not require transfer through an FFL holder.
*AR15 Parts Compatibility: See Installation Instructions for more information.
INSTALLING AMBIDEXTROUS BOLT RELEASE: If purchasing the "Stripped Lower" option the ambi bolt release will come loosely assembled in the gun. The left button will slide rearward allowing the assembly to be removed. When reassembling the button(s) you will need to use the included spring and detent to lock the button in place. Drop in the small spring first then insert the detend until flush. While holding the detent flush slide the button into place until you hear a click. Be careful with this step as it is easy to launch that detent into space. Or your eye..
Fit Issues:
In some situations different stock/brace endcaps may allow the lower to rock back and forth a little or "wiggle". An easy fix for this is to add some thickness to the metal tab where shown below. A small rectangular piece of electrical tape cut to fit this space usually works perfectly.
