Getting that itch again and looking for my next SBR project. I have nailed it down to these three options... 1. CZ Bren 2/806, middle of the road in regards to price, shoots 5.56, folding stock, sexy and I know will work. 2. Beretta ARX 100, cheapest in regards to price, comes as an SBR, quick change barrel, COMPLETELY ambi as I am a lefty, folding stock but kinda ugly 3. Arsenal 106, would be more of a project as I would have to send to a gunsmith to get it cut down but AK reliable, expensive magazines, folding stock, AK pretty.
