Added this to my personal armory SAT. I got a catalog from a company called Federal Arms Corp. They had advertised this as new Overseas military contract cancelation, $499.95 Heavy barrel under handguards 20 inch barrel A2 style muzzle break sling and mag. Found out that it was made by Hesse arms. Now over at Ar-15.com they were bashing Hesse pretty bad so I was A bit nervous. When I picked it up and cleared it it was NOT locking open on an empty mag. Started to panick a bit and I know that it showed. Part fit was very good NO slop in receiver fit mag catch tight bolt catch tight too. Ask some guy to take a look at it and he was ex-military and said it was tight too. took it home and field stripped it sun morning. Take down pin and pivot pin very tight to get out. Had to use punch and rubber mattel to get them out. Since this was my first AR was a little nervous with it as mentioned above. Took about 2 hrs with it put it back to gether and put it away. Monday-- ON the line time: Went through 100rds of mixed ball UMC PMC and American Eagle not a bobble. Took some time but sighted it in for 100+ yards clover leafed 4 rounds Got used to it and such(little different from my mini-14) mags started to lock back bolt when empty(was a mag issue not gun). Was getting happier by the minute over all I am very happy with this product! Well now how do you guy think I did? The cost of the rifle was $558 out the door from my dealer. Any tips for the new AR owner? I WILL get surplus mags this weekend at the gun show. Also more ammo. Thanks gang....DAROGUE1
