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.

I bought a brand new Colt M16 BCG with the shrouded firing pin from Jim of Police Supply (they're industry partners) at the Equipment Exchange for about $175 plus shipping.

I used the BCG on my new Colt M16A2 upper.

Jim's member name is GunDealer3, just call him or send an e-mail, great communication and fast shipping.

My favorite is the auto bolt carrier group. I see no reason to have a semi unit.

ar15inmn, thanks for the info.  I thought that I had it right, but I didn't want to order the wrong carrier.

Alpha-romeo3, the carrier replacement is FOR a rifle I bought from Jim.  I never thought to contact him about a bolt group.  Since he is significantly cheaper than SAW, I appreciate the input.
