I did not have much luck with my L1A1. It was built on an Imbrel receiver, put together by century. It was one jam after another no matter where I set the gas regulator. I had six mags same deal with the mags bang bang jam. I finally got rid of it at a gunshow and picked up an AK (norinco MAK 90) been an ak man ever since. The reason I chose the L1A1 is I am a lefty and cocking the bolt is a lefty sorta thing. I've seen the new FN parts .223 that Bobcat weapons (now Red Rock Arms) has come up with. Looks interesting, seen it at the SAR show and thinking hard about it (1400 price tag ) it takes AR mags so it could make a lefty happy again. I heard that FN FAL were prone to jamming. I did have good results with Izzy ammo but it was loaded to hot for me (seeing casses split horizontally wigged me out and that ended my use of Izzy machine gun ammo .) Its my 2 cents worth for what it matters.
