I am interested in purchasing a Colt bolt and carrier. The bolt will be a spare, and the carrier to replace the original which came with my LE6920. The original carrier does not shroud the firing pin and I am having problems with bent retaining pins. These are the options from SAW:
SA05010 BOLT GROUP, SELECT FIRE, M16 (1965-PRESENT) 279.00
SA05009 BOLT GROUP, SEMI, L/E W/ M16 COCKING ANGLE & PROTECTED FIRING PIN (1998-2001) 199.00
SA05011 BOLT GROUP, SEMI, SP1 (1967-1990) 199.00
SA05008 BOLT GROUP, SEMI, SPORTER (1991-1997, 2002-PRESENT) 179.00
Is the SA05010 the carrier (with bolt) that is currently shipping with LE6920s? Does it have the shrouded firing pin? Does it have a long closed end which adds weight and some believe increases reliability by slowing down cycling?
Does the SA05009 have a closed or open (half-moon) end? I assume from its SAW description that it shrouds the firing pin.
Thanks for your help.
