This a 5.56 ranch carbine. It takes ar15 mags. I have had it for years and simply quit shooting it so here it is. The round count is right at 250 and yes it shoots great. Some of the specs on it are:

P-mag 10rd magazine.
Marksman adjustable 3-5 pound trigger.
Lightweight synthetic stock.
Soft rubber butt pad.
One piece three lug bolt.
Power bedding integral bedding block system.
0-MOA factory installed one piece Picatinny scope base.
Compact 18"  1:8 twist threaded barrel with thread protector.
Easily accessible safety tang.
A pair of mounted swivel sling studs.
The price is $450 shipped and it must be a USPS M.O.  It must go to your FFL from a non FFL and it will ship USPS. If you any questions let me know. Thanks.
