AR-15 BS Thread

Ok, figured that was the company brand since it’s the only thing on it

 

got a pic of the whole rail?

 

So, my first AR. Built from a parts bucket, really cheap. 300 AAC 10.5in barrel. PSA lower, not sure about upper and barrel.
I’ve got a Nomad Ti in jail that will go on it.

 

Clean. I wish I could legally build one like that in the state I live in.

 

Nice! I call the 510C the F-150 of Holosuns. I have two!

 

I wanted the green dot version, but this one was $237 new and too good a deal to pass up. I’ve got the riser plate on order as I think I want it a little taller.

 

If I were going to buy all the parts to build that, what would it run me?

 

The lower is a PSA blemish that was around $135. I paid very little for the rest as they were someone’s extra parts they wanted rid of. Nothing has a manufacturer on it, so I doubt it’s more than $300 total for everything on the upper.

My goal was a very utilitarian SBR. I’ll be happy if it shoots inside 3 inches at 100yds and goes bang every time.

The suppressor will cost more than the rifle.

 

Gotcha. Thanks for the info.

 

So the upper cost as much as the tax stamp will hahahaha.

 

Basically. Pretty inexpensive build, even with the stamp.

 

Went out recently to my local range (Metcalf)

 

So let me pick y'alls brain a bit about this build.

Went out and shot it yesterday for the first time. Love it. First time I've shot a 300 BLK and there was more recoil or slamming of the bolt than I expected. Maybe it's normal, not sure. My subsonic loads had no problem cycling and locking the bolt back, even without the suppressor installed.
It's a PSA blem lower with a standard carbine buffer.

Should I not worry about it since it's working, or should I experiment with a heavier spring or H(1-3?) buffer? I plan to run thousands of rounds a year through this and don't want premature wear if I can help it.

 

where does the brass go when it ejects?

 

Trying a different spring and buffer would be easy. A bit more difficult would be to try an adjustable gas block. But if you want to run thousands of rounds through it and want it to work flawlessly with all ammo you have to have some compromise somewhere. Subs vs sonics are going to shoot different, perhaps a selectable gas block might be the ticket.

 

The brass is hitting the deflector on the receiver.

Where does it throw it? This is why he's asking:

The goal of this rifle is low cost and simple. Right now it is shooting everything I put in it. I was just surprised how well it functioned with subsonics and no suppressor. I assumed I would need the back pressure from the suppressor to lock the bolt.
