Finished AR15

[Refleks]

Most of this was from Primary Arms (I went a little crazy on their black friday sales lol)

Very nice, congrats!

Looking good!

Build list?

Looks good. I'd recommend upgrading the grip and stock, but this nothing more than a personal preference. I really like that low-riding optic, but it's too hard for me to get a good look-see without it riding a bit higher. I am going to play around with that on my current build.

Very nice build! If you are like most of us you probably already have some future upgrades in mind.

Thanks for the comments!

The AR-15 is a slim gun, so it always frustrated me that most of the hand guards and quad rails out there had such a large diameter, just wasn't comfortable to me. That's one of the reasons I went with the alpha rail.  It does heat up a little faster than some others but I'm happy with it so far.

 

As far as the parts list...

 

I got the upper on sale at Primary Arms, it's a 16" ATI with 9" Troy Alpha rail. I never heard of the company, and there isn't much information out there.  Ideally I would have done a BCM build, but it was a good price and I didn't want to wait another year gathering parts.  The upper had everything including BCG so I snagged it.

 

Lower is a T-15 with your standard M4 stock and Magpul trigger guard.

 

The optic is a Primary Arms micro red dot (the one they had on special black friday) and 3x Long Eye Relief Magnifier with flip to side mount. BUIS are magpul.

I prefer mid length but so far I'm happy with it's simplicity and slimness.  I'm eventually going to replace the optic with a real aimpoint micro, and plan on changing the grip and stock in the future as well.  I have been thinking about weapon lights but not sure if I'll add one to this build.

What gas block did you use under the Troy rail?

 

And for anyone else, which adjustable gas blocks will fit under there?

R_Bert, which Troy rail do you have in mind?

I have the TRX308 13.8" coming in today. Not sure what the clearance difference is between that and the AR-15 version is, if there is one at all.

Anyway, I was just reading the reviews at midwayusa and a couple guys gave the syrac ordnance .750 adj block(non clamp-on) a 5 star rating saying that it fits under their 12,5" and 13.8" TRX rails for their 308s.

I had the same question and just found that today. I just don't know if I should get the clamp-on or non clamp-on for the RA ultramatch barrel

in regards to the OP, that's a nice looking rifle!

Apologies to OP for sort of hi-jack.

 

I am interested in the Troy Alpha and a similar look as OP (may have a Magpul CTR or a Ace Skeleton on mine). 

 

I saw the Syriac blocks, and they are high on my list, especially if they will fit under the Alpha.

 

Building a .204 Ruger in what I guess is mid-length or carbine.  Looking for 18"-20" heavy bbl (will have a .936 block) and the hand guard to cover as much bbl length as possible.  I am hoping that I will be able to access/adjust the gas block through the side of the rail.

No worries! The gas block came with the assembly no brand markings. Someone on another forum said they had mossberg barrels.
