As featured on the Armalite website:
This is their M15A2 National Match upper receiver.
Featuring a forged A2 upper, 20" stainless steel 1:8 twist barrel with free floating barrel sleeve. Black handguards. I have had this since 1999, only put about 300 rounds through the barrel and I 'broke in' the barrel by punching the bore after the first ten rounds. Sells new for $675.00 I will sell mine for $500.00 shipped after receipt of postal money order or similar. Open to an offer but no trades please.
I do not do paypal due to their anti gun policies, so do not ask please.
