Just built this AR Pistol....

[BradMacc82]

What it would've looked like, if not for the barrel issue. (May swap out that rail for a uninterrupted one though...)

And if anyone was wondering what I meant by the "clocked" position of the index pin in relation to the gas-port, well here you go -

That's something you shouldn't see, from any maker, but it happens to all of them at some point in time.

Brad you referring to the barrel index key ( allows proper alignment of the barrel to the upper receiver) to the gas port under that YHM gas block correct?

Have you removed that gas block to see how far that barrel gas port is to the barrel/upper receiver is off?

Your gas block could have moved as well. The port on the gas block is a lot wider than the barrel gas port hole.

Just a thought. I'm sure you did that. Just thinking out loud.

Correction:

I looked at the photo on my CPU rather than the iPad. I now see it. In addition, Noveske pins their own gas blocks

I like it

Oddest damn thing, I tried it again today. Got everything to line up properly..., I'm wondering if the barrel extension is on there properly, or if I'd somehow gotten things out of whack yesterday.

This isn't my first rodeo, but I won't say me f'ing something up is out of the realm of possibility.

It's getting interesting for sure.

Good Deal.


One way I check the alignment of the gas block port to barrel gas port:

Stick the gas tube in the gas block (you can just hold it) , and with it aligned (gas tube port facing DOWN), blow into the gas tube. You will hear air exiting the barrel.

Now I just need to find another 5/64 x 5/16 spring pin, damn thing launched itself yesterday, and haven't been able to find it since then.

Been there done that.

I buy a lot of my spare parts at http://www.JSESurplus.com

These ladies are gold. They NEVER once inflated their prices during the recent frenzy.

You went full retard, never go full retard




On a bonus note, I finally took mine out today! Sighted her in with a box of .300 whisper then moved onto the reloads. Had some good results with H110 and Lil Gun and hope they were enough to point me in a good direction to finalize a load soon. Was not expecting so much kick though, that made it that much more fun

Maybe just a little...

Supersonic, have had good results with H110 and Hornady 110gr Vmax's. Got a few pounds of Lil Gun to try later on.

Installed CAA Cheek Rest

I two toned it using Brownells Coyote Alumahyde II. Its close, but not a perfect match.

Very nice! I need to order that cheek rest before I forget.

how does the cheek rest work with the phase 5 buffer tube?

 

[jcbvh]

how does the cheek rest work with the phase 5 buffer tube?

It actually fits snug on its own. I'm just going to add Velcro.

Others have used small black cable ties.

As far as feel. Its great! Well worth it IMO.

This thread is pure torture!!!

Is the cheek rest legal?

 

[Happa Haole]

All beautiful pistols I believe I'm inspired for my next build. Thanks everybody

Is the cheek rest legal?

Yes. Scroll through the AR15.com link below to the 3rd ATF letter:
