Thanks guys, ill get some .223 mags.

Any polymer mags you all like? Looks like magpul doesn't make a .223 Pmag under 10 rounds.

L5AWM® 5 Magazine - Lancer Systems

Lancer set out to design a better 5.56 magazine; one with the reliability of steel and the durability and weight of polymer. The L5 Advanced Warfighter Magazine (AWM®) is that magazine. The L5AWM's exclusive hybrid design includes a hardened steel feed lip assembly molded into a proprietary...

I think most 5 round mags use the same magazine body as 10 round magazines and just use a follower with longer legs. Unless you're required to use the 5-round magazine for hunting there doesn't seem to be any other advantage to them. Could be wrong on that, but that's how they appear in pictures.

If you're buying, not using what you have, why not get 300bo mags?

If you have some recommendations for 300 blackout mags that are 5ish round capacity, I'll probably do that. I am pretty green on this AR world, so bear with me...

Well thats too bad.. I was hoping for a smaller, lighter, shorter mag. Ill have to look at the game regs in my state. I can't remember if we have a 5 round limit.

For an UL or ULUL hunting gun, it sure would be nice to nock an ounce or two off with a smaller mag. Are there any options out there like that?

In this case, the 10 round mag should be slightly lighter than 5 round mag having less material in the follower. More capacity, less weight. Win-win!

I doubt you'll save more than a half gram on a mag.
The Promags & Lancers are a little heavier than stainless & aluminum might save you a half gram, but they're known for deforming the feed lips.

Unfortunately, a 5 round length mag would sit inside the well.

I've been shooting a lot of 5.56/223, and have an LS Wild pack pillow and rear bag en route. I'll be interested to see if the ULUL is any harder to shoot off field positions than my bolt gun

One of the guys on here with the time and coin for it should take a ULUL to a shoot2hunt 0-600 class and see how they compare to the bolt guns. I bet they would do pretty good if there were no break downs

I ordered an asc or duramag 5 round for ARC/Grendel and turns out it was the same as a 10 round body but super heavy because the spring was super dense and filled up the extra space in the bottom.

I’ve since ordered a standard spring and converted that to a 10 round mag

If anyone is interested in my portless BSF carbon-fiber-tensioned barrel in 6mm ARC, PM me. It is 16 inches long and weighs 1 pound, 7.9 ounces. The muzzle isn't threaded, so you'll save weight by not using a suppressor!

It's not been fired much and is accurate as hell. I've since turned the build below into a 5.56, so the 6mm ARC barrel is up for grabs.

This is the same for the lancer mags I posted. I didn’t realize you were trying to cut weight. As stated, they won’t do that.
We have a 5 round mag limit for semi-autos here in OR.

You can't break apart the SPARC! That's one of the OGs.

Thanks guys for clearing that up, showing how green I am with these fancy new AR's

Ooooh, just a quick heads up.

I just got a stock alert notification that the BCA lightweight, 16" 1:7 5.56 barrels are back in stock at $63

 

[Hardly_Hangin]

What barrel are you using on your solo?

Its actually the same faxon 16.5" pencil barrel i had on my gasser, just swapped receivers and closed the adjustable gas block all the way. Accuracy was MUCH better than it was as a gasser.

Ran a pressure ladder test with my new hand loads today and I'm very impressed. Loaded 2 batches of 6 different loads, one batch with 75gr otm and one with 77tmk, starting at book start and ending at book max in 0.5gr increments. No pressure signs that i could identify, and each 6 shot group was 1ish moa with varying powder grains and coal.

It looks like those have gas ports in them if it is the ones I am looking at... what is the most accurate (non gas port) pencil 223 wilde barrel yall have found?

Samson gas block is something like 0.2oz. Put it on upside down and turn slightly

This barrel with a cap screw inserted into the gas port with red loctite.

Not a huge sample size, and not by a lot, but it shot tighter than my Shaw portless.

The Shaw portless currently is the only “answer” here.

That said, the BCA pencil barrel, in my opinion, stands alone on precision center fire barrel to dollar spent ratio.

Curiosity, do the light weight (non ported barrels still have the bulge in the middle they just do not drill the port? Or are they thinner full length and not port and thierfor lighter?

If they have no bulge and are lighter and you save the $50 (after shipping) of the Samson gas block, you could possibly spend the same $ but get a slightly lighter setup.

(You would just lose the option of turning it into a gasser at a later date.)

Please educate me as I have ever seen an ar barrel that was not ported.

You are referring to the “gas block journal”. Yes it cuts weight not having it. Some non-ported rifles have been ordered without the journal. X-caliber, you don’t get the option of no journal. So it depends of what company you order the barrel from.
