ALL ITEMS SOLD I picked up a 5.45 AR-15 barrel from AR15hardware.com (16" Chrome Molly M4 5.45 x39 barrel), and paired it with a Model 1 Sales 5.45 bolt and larger 5.45 firing pin kit. About 650 rounds down the pipe 5.45 barrel + 5.45 Bolt + 5.45 Firing pin for $150. I just zeroed the rifle last week, and it's still shooting straight I have a sealed spam can of 5.45 ammo, that's 1080 rounds: $129, or $100 and 350 extra round if you buy the barrel/firing pin kit and magazines as well. I also have 4 C-product 5.45 magazines available at $10 a pop. AMMO AND MAGAZINES SOLD, PENDING FUNDS I bought this stuff to have an inexpensive plinker, but now the local range is telling me that steel penetrator ammo is no go!
