AR-15 BS Thread

Maybe it's because I'm looking at .223 Wylde barrels? I'm going to build with an 18" .223 Wylde with a mid-length gas port.

 

Not sure if you're stuck on gunbroker or not but I can find lots of 18" 223 wylde barrels that specify m4 feed ramps.

Mobile android link may not work for you but it's just a Google search for "18 223 wylde m4"

 

Thanks, guys, for the advice and patience. I'm not hooked on any one place to buy components. I've used corporate websites, eBay and Gunbroker to acquire components so far. I ordered an assembled FDE Aero Precision upper last night through Gunbroker for $85 shipped and a matching free float hand guard with barrel nut and shims through eBay. At this point, I need the barrel, gas block, gas tube and muzzle break. I also want to put an adjustable, fixed stock (have the components for a carbine stock on hand) at some point.

Any thoughts on Bear Creek barrels? I found some on sale on Primary Arms. I want something that is going to give me good accuracy...but I'm not going to compete nationally so good is OK.

 

Haven't used bear creek personally, but was looking at them when I built my 300 BLK... Ended up going with a Ballistic Advantage barrel and couldn't be happier. Great quality and accurate, all I could really ask for.

 

Have you checked out DSGARMs.com? They usually have a pretty good selection and offer a .mil discount.

 

My upper is a bear creek built 6.5 grendel. It's been reliable for me thus far, haven't shot it for groups yet.

 

Excellent triggers for (now) under $100!

Have you looked at Larue barrels? $200ish and crazy accurate.

 

I have never used Bear Creek barrels, but I own a couple of their lowers and wasn't a big fan of the coating they use, although no actual performance concerns. Check out faxon barrels, used them on my last 2 builds.

 

I second Faxon barrels. I really like the one I used on my 18" upper build.

 

Has anyone found a need for Go/No Go gages? I have a set for my Mosins but am wondering if the mil-spec tolerances offset the value of the gages. Then, on the other hand, I keep thinking safety.

 

I plan to pick up a set for quick-changes of my Savage barrels, but in an AR15 most people shouldn't need them. If you build your own rifle they're not a bad idea for final fitment checking.

 

I'm speaking on my own behalf. absolutely YES on the go/no go gages.

 

So, since I am going with a .223 Wylde barrel, should I go with 5.56 gages or .223? I assume 5.56 since if that will chamber, a .223 will chamber, too.

 

If i had a set of gages it would've saved me a big headach figuring out what was wrong w/ my 223 wylde barrel a while back. Seems like a good investment

 

That’s a good question?I believe I would have to agree with you

 

Are they totally needed....probably not. Especially if buying name brand stuff. If using cheap no name stuff I'd definitely use them. When talking AR-15s that is. They are pretty cheap though so if you plan on more than one build its worth picking up a set.

Another option is to just go to a gunstore that has a gunsmith. Just call ahead but the local one by me will usually check it for free. It takes all of a minute or two to do so its no big deal....plus they know ill more than likely end up buying something lol.

 

Built my first lower last night. Took about 2 hours watching videos and only managed to launch the buffer detent across my kitchen.

AERO m4e1 lower
AERO lpk
Rise armament ra-140
Kns anti rotation pins
BCM mod 3 grip
BCM qd end plate
KVP 4.3oz buffer
Jp enterprises spring
SBA3 tactical brace.

 

Nice! I had one of there lowers also. sold it looking basically like yours there but a different buttstock for $250

 

For the price point, aero makes some great stuff. Went together pretty nicely, only thing I might switch out is a ambi safety since I'm a lefty.

 

I agree, I’m an ambi shooter so that’s must in all my setups.
