Bought an AR-556 a couple months ago. Haven't had time to get out and shoot with it yet, but I've been gearing it up with add-ons (vert grip, reflex sight, sling, extra mags).

Yesterday I was taking a closer look at the BCG and noticed something like a small notch in the groove on the left underside of the carrier, right at the front end.

I've only done a preliminary check of the charging handle and bolt catch a few times to get familiar with how it functions.

I'm hoping what I'm seeing is actually part of how the BCG is machined and not any damage I may have caused inadvertently.

I'm new to the AR game, so I'm not sure on this, but it just seems to me like the front ends of the grooves on the underside of the BCG should be identical.

It'd be a real bummer to discover damage before I've even had a chance to put any rounds through this thing.

I'll post a pic when I get back home, but any advice would be welcome.

General advice on any further things I should do with the rifle before taking it to the range would be welcome as well; aside from accessories being added, it's pretty much fresh out of the box.

Welcome!

Give your rifle a thorough cleaning and lubricate it well.
+1 I am with Ditto, lubricate the crap out of the bolt carrier, and go out and enjoy it. The barrel should settle down after 150 to 300 rounds and provide very accurate groups if you do your part. If you run it with aluminum mags, brownells are top quality, if polymer magpul and hex mag do an awesome job. If you decide to sight it in, start at 25 yards, then go out further to avoid wasting time and ammo.

Biggest thing, ENJOY IT!

I’d run it “dripping” right out of the gate............
:D you know the first time one of my buddies saw me hose down one of my bcg's after cleaning it he was like, I need to run mine that way? I replied yep dripping wet. I use prizm which is a teflon gel lubricant, its produced good results, no stoppages. I use less later on but its still lubricated. Most think your exaggerating when you say dripping wet.:eek:

Tacky, the upside of running it dripping, other than zero stoppage...........the BCG cleans up in a snap. Hell, nothing can stick to it, lol

Nice AR’s to start with. I just picked up a .300 blk AR-556 pistol myself.
I have also owned a Sr-556.
Been into AR’s since I joined the Army in 74’. Been building and using AR’s since.
The Ruger AR-556 seems to be a well built entry level AR.

:thumbsup:

True that, which none seem that bad since I clean mine in my parts washer with mineral oil, clean up is a snap.

I think you could possibly wipe it down with a rag and clean it after its been fired well lubed too. If you had no other option.

300 rounds? I'll need more FMJ. Lol!

Already had the reflex sight boresighted, so now I probably just need to break it in.

PMags all the way. It came with Magpul furniture, including a PMag.

Yeah, your gonna need more ammo. I probably shoot 100 rounds through each firearm I carry with me everytime I go to the range, however I reload so I have way more than that on hand. I usually go to the range atleast once a week. Reloading 5.56 is pretty cheap, you can buy 100 once fired 5, 56 cases for $3 or $4 dollars. Then take them, swag the primer pocket to remove the crimp ring, size them, trim the to size and roll on. I use the cases for .223 and convert to make 25-45 sharps.

I would say look at these places for deals on ammo.

Natchez shooters supply
Graf and Sons
Midsouth shooters supply
Primary Arms
Palmetto state armory

Those are some off the top of my head....

Thanks for the intel! I've been grabbing from Academy when I can, but it'll be nice to have other sources.

Haven't gotten into the reloading part yet, but I'm sure I eventually will once I get some other stuff squared away.

No problem, us gun people have to stick togather.
I used to purchase federal .223 remington 55 grain fmj 100 round value packs from walmart years ago for like $32 a box. But seeings how I have alot of bottom feeders and different barrel lengths, twist rates etc I started rolling my own to get the best accuracy from each. I load these .223 loads.
40 grain v max at 3700fps
52 grain sierra bthp match 3000fps
55 grain extreme fmj cannlure 3000fps
75 grain hornady bthp match 2600 to 2700 I believe.

I cannot remember the last time I bought factory ammo. I load for these calibers as well.
Pistol
380acp, 9mm, 38spcl, 357mag, 40sw, 44spcl, 44mag, 45acp, 45colt, 454casull, 50ae
Rifle
.223 rem, 243 win, 25-45 sharps, 6.5 grendel, 6.8 spc, 270 win, 7mm rem mag, 30 carbine 308 win, 30.06, 7.62x39, 338 federal, 8x57JS, 450 bushmaster, 50 BMG. Probably a few others I forgot. Some of my rifles have never seen factory ammo.:D

Check those sites out though, they usually have sales going regularly this time of year, I know they do black friday, thanksgiving, christmas, and new years sales where you can rack up good deals. I do the same. If I can be of any help, just drop me a line or a PM if needed.

Hey mark, here is a good example of how I run mine.....
Tacky, when my son bought his first AR he had it all apart and asked me if there was anything special he should do. I said “yeah, make sure you hose down the BCG with the Balistol “ and left. I came back later and he said “how’s that?” I looked at and said “ that’s a start....hand me that can.”

Also, did you ever look into the brass catcher from EL MFG??

Will do.

Currently stocked up with; Federal American Eagle 55gr FMJ, Hornady Frontier 55gr FMJ, and Hornady Frontier 75gr BTHP.

Still got more stocking up to do if I'm gonna feed it 300 rounds of FMJ to break it in. 😁

Agreed, us gun folk really need to stick together. Thanks again. 😄

I have shot alot of american eagle, I remember many years ago buying remington umc 223 ammo in a yellow box, heck that was more than 20 years ago. Keep them in the 10 ring brother!

Seems like some good advice just bought be some Balistol. Should I use the Balistol to the barrel also?
NO.....Just the BCG. I use Balistol on my 1911 barrels, (disassembled) as a pre-cleaner and it works wonders. But if used in an AR you would never get all of the Balistol out of the chamber. Oily chambers and brass don’t mix well., the oil will not allow the brass to expand and seal the chamber properly, this could cause an unsafe over pressure situation. I’ve seen guns come apart because of this, albeit they were bolt guns.

I've noticed that .223 seems much more readily available than 5.56 NATO at the brick & mortar shop where I've been buying ammo.

Ruger's page for my rifle model says that either will work, but I'm wondering how much difference there is, and are there any caveats I should be aware of?
