CTH84's Review of Moriarti AR-15 5.56x45mm NATO M4 Barrel Threaded

Cleaned and oiled barrel. Loaded first round and bolt got stuck chambered. Was able to clear weapon and remove bolt and round casing. brought back home and did some investigating. Found that the barrel has to tight of headspace. Tried 2 functioning bolts out of running AR-15's and same result.
