This is a take off from my factory Bushmaster 16" HBAR carbine I bought NIB in September 2004. It is used, but in good shape. Includes barrel (w/ A2 FSB, bayonet lug, sling swivel), barrel nut, gas tube, gas tube roll pin, delta ring assembly, carbine handguards, A2 bird cage flash suppressor, and crush washer. Barrel is as reads, "B MP 5.56 NATO 1/9 H BAR." This is chrome lined with standard rifle extensions. Asking SOLD
. I accept USPS money order. Thanks for looking.
