Name That Part! December 2009 (AR-15 Edition)

[Miso Beno]

Welcome to the first monthly "NAME THAT PART." In these threads we will feature a single firearm for one month and every day during that month we will post a photograph of a feature or part on the firearm.

What we need YOU to do is to tell us what we just part or place on the firearm we just posted a photograph of. Three times during the day we will post hints and when we post the next part we will identify what the last part was and who got it right.

Lets get things started!

Bolt catch/release, bottom side.

[Clinotus]

Rear magazine release.

[Danube]

Bolt catch/release, bottom side.

I think you are correct.

[Miso Beno]

It is not part of the Fire Control Group.

It is not related to the rifles magazines or magazine retention assembly.

[Clinotus]

I fold.

[terraformer]

It is not part of the Fire Control Group.

It is not related to the rifles magazines or magazine retention assembly.

What other moving parts are there?

[Miso Beno]

What other moving parts are there?

The extractor, ejector, bolt hold open, and the buffer assembly to name a few.

Incidentally, the back of the extractor, with the extractor spring is what is in the photograph.

dust cover.
Also, what lens are you using for these shots? dedicated macro lens or an extension tube?

[Danube]

I pulled my AR out of the safe to play along with this!

I will take, What is a Dust Cover for $200 Alex.

[Miso Beno]

Danube and Hizzungfartoolow nailed it.

That's easy: buffer tube screws and retaining thingy detent whatchamacallit.

[Clinotus]

That's easy: buffer tube screws and retaining thingy detent whatchamacallit.

I'm going to trump sir Fang and identify the parts as he as no AR15 and thusly is making things up. :cav:

Buffer extension tube.
Detent pin.

[Danube]

Detent!

[Steve Balmer]

Riding that detent wagon!

[Miso Beno]

You're all correct. It's the buffer retaining detent installed in a receiver.

[Danube]

I'm stumped on this one.:sad:

[mbquimby]

is this not the end of a bull barrel?

[Miso Beno]

is this not the end of a bull barrel?

It's the business end of a barrel which is good enough for me. (It's the business end of a Smith muzzle brake to be precise.)

I'll go easy on you guys this round. New Years hangovers and all that jazz.

[Fang]

Forward assist?

[Clinotus]

I'd tap that like a..... Forward Assist.

[mbquimby]

I'll be more specific....it is a dusty aftermarket forward assist.

[Clinotus]

^Bump^

[Miso Beno]

It's a stock forward assist.
