Bolt carrier question... - Steve357 - 02-17-2012
Are 223/556 and 6.5 bolt carriers interchangeable? I have a nickeled carrier I'd like to use in my Grendel.....
Bolt carrier question... - Drifter - 02-17-2012
Yes
Bolt carrier question... - leopard6.5 - 02-17-2012
Steve357: Yes but all .223/5.56 carriers are not the same.
There is a difference between an AR-15 and a M16 carrier.
The M16 carrier has more mass( weight) than the AR-15 carriers and thus the M16 carrier helps to slow down the movement when fired.
This is especially helpful when it comes to the Grendel as sometimes it is over-gassed.
It's best to use the M16 carrier and a buffer weight that is the same as a regular rifle length buffer.
Good Luck and welcome to the horde.

Ditto on what Lee posted, with the Grendel a heavier BCG and recoil buffer are advantageous.

The advice on the heavier bolt carrier is good. I would add that you may want to look into an adjustable gas block. I have one on my 18" and it was really useful when setting the gun up.

But you have to consider, any single part that can be used in full auto, can be illegal, although it takes 6 parts to make a semiauto a full auto. Ownership of one part can show intent to manufacture a full auto. The bolt carrier is the one piece that is not clear, but I won't own a M16 carrier because I don't want to bring any doubt into the scenario.

fanofflyn: I remember reading here before and I'll keep looking for the post, that the fed made an exception for the bolt carrier so using an M16 carrier is not considered a full auto part.
When I find the post I'll post it since it also had a copy of the fed's ruling.

M16 bolt carrier is not illegal for use in AR-15:

Thanks for the info, I'll take all of it under advisement....I cant do the adjustable gas block, It's a mid-length with a rifle length guard with a low profile gas-block....
Bolt carrier question... - leopard6.5 - 02-18-2012
Thanks Drifter for finding that about the M16 carriers. I knew I had seen it somewhere.
Steve: There is a thread on the forum about a front adjustable gas block so you could use the rifle length handguard with your mid-length gas system.
Here's the link: http://www.65grendel.com/forum/showthread.php?2073-click-adjustable-gas-block-w-front-access
Good Luck.

Hey thanks for the info on the bolt carrier. I have always been a little paranoid about big brother.
Bolt carrier question... - sneaky one - 02-18-2012
I believe all the AA carriers, in their uppers are M- 16 style/ wt. My AA upper came with one. Totally legal.
Bolt carrier question... - LRRPF52 - 02-19-2012
There are plenty of manufacturers who only use M16 carriers, and they are well-advised legally. DD, BCM, Spike's, Noveske, CMMG and others provide this as standard. None of them are in the business of going out of business.

I've been told Colt has shipped M-16 carriers in it's semiauto Civvy/LE carbines for years
