AR-15 BS Thread

When you built yours did you add the buffer spacer to the other side of the spring?
Disclaimer: I don't have an answer to your question, I'm building my first AR9 and am curious if it actually helps cycling.

 

No, no spacer. I think that's only needed for certain setups.

I have 7.5 oz buffer and a 308 spring. Runs flawlessly. Everyone's setup is going to be different though. I use a Spinta precision barrel and their bolt carrier group, I called them and asked what they recommended to figure out what I needed.

 

Thanks, I know they like the heavier spring due to the blowback design. But, damn that's a heavy buffer. I ordered the spacer anyway since it was only $10. I'll check with them to see what my options are.

 

You might be able to use a captive buffer spring set up depending on your bolt carrier. Mine is weighted, so I had to use a conventional setup.

 

Spinta Precision blemish upper $32!!! They're usually $80. Great company, if you need a good upper, jump on this.

Aero has some good deals on blem complete lowers.

Fuuuuu it's already sold out

I wouldve felt worse if it was a 9mm bolt or something but still

 

Was a seriously good deal. I would have bought one, but Christmas has killed my fun money. I have a barrel and a bolt carrier group from them, I intend to get more. Great company, awesome customer service.

 

Yea I've been eyeing them for a while for the right bolt and barrel to be on sale to start my 9mm build but so far there hasnt been anything really worth while to me.

 

Although I did just find this nordic components slick side for $40 I think I just found my upper

 

Not sure if you are building a pistol or a rifle, but I got their 8" stainless 9mm barrel blemmed for liik

Nice! I have a slick side myself. Perfect for a 9mm build.

 

Scott, did you finish your AR build and if so what parts kits did you use for the lower?


@GHOST SHIP - same question as above..................

time to grab the bits and get cracking on.......................

 

Bear Creek also had side charging uppers for $118. Not sure if that sale is still going on but it went on sale yesterday. They have a deal everyday until Christmas.

 

I've been reading and thinking about what was suggested on here. Originally I wanted a M&P 15-22 b/c I figured it would be cheaper to shoot plus I didn't know how much "range" time I would have or use a .223/5.56 model. Someone here suggested that I get a .22 conversion kits by CMMG. I've been looking at videos and reviews and the only negative that I've seen is that b/c the .22 would be shot out of a bigger barrel, it's not as accurate as a stand alone .22lr model. But the groups isn't that bad either so I don't think it would be that big of a deal. My concern now is, what kind of sights or scope would work on both calibers? I like how the 15-22 has the Magpul front and rear sights but the 15 Sport II has the "A" front sight. I'm not sure if that's what it is called or not b/c I'm a newbie at this. If you put a scope on it and shoot the larger caliber and then shoot the .22lr, would it affect the scope accuracy? Also, what would be some accessories that would benefit both calibers? Sorry for all the questions and I'm sure I will have plenty more.

 

I don't have the 22lr conversion, my suggestion though would be just to build a new upper. Then it is an easy swap and you wouldn't have to worry about new scopes or adjusting the sights. For $200 bucks though, I'd get a Ruger 10/22 and make it look like an AR if that's what you want. I've had a 10/22 for 10ish years it has never ftf or fte, it eats everything you feed it and will give you clover groups at 50 yards.

 

I've got a Marlin model 60 .22 now which I know doesn't have many mods available like the Ruger. I haven't been interested in an AR style until lately, my uncle bought the Ruger 556, I shot it and I was like "oh I like this". Being my first one that was one of my main reason of getting the M&P 15-22 to learn on and let me wife and daughter shoot some.

How would you build a new upper? What parts would be needed and where would I purchases these from?

 

WHY IS THERE A HAMMER ON YOUR DESK??????

 

you see hammer I see proper motivation to fit

 

so in this case, it is a persuader?

 

Yaaa! one of my Larues was like that also
