Have any of yall seen alot of MIM extractors on BCG's these days?
While at the range today a friends carbine started having some extraction issues.We took a look at the Bushy and found that the extractor had lost part of the claw....the metal looked porous at the fractured area.Further examination I found the underside of the extractor had an obvious MIM mark.
Luckily I had a spare BCM SOPMOD upgrade kit in my range bag,so we coninued on without interruption.
But the MIM extractor made me curious so I went home and took a look at my recent Armalite take off bolts from last year.All of the new bolts have MIM marks on the extractors,while my old Armalite bolts from around 2000 have machined extractors.
Anybody know when the MIM extractors become popular with the manufacturers?
