I have an M1A in a precision stock that weighs like 12lb no scope. I hate a few things about it but weight is not really one of them. I’m set up to reload.308 and everyone I shoot with has one so I’m gonna stick with it
I just graduated high school, I don’t have Proof CF money, but I wish I did and hope I will in the future. I’m sure they’re awesome
Fair enough. You’re way ahead of me straight outta high school! Either of those barrels will be excellent. I prefer 1:10” for heavies
For what you're looking for, I have a feeling this would do you just fine. https://www.opticsplanet.com/lothar...arrel.html?_iv_code=3ZH-ATB-AR1-A0-N-P-030-10
From what I can tell a criterion 20” is about $500 with a headspaced bolt. I can a shilen of the same length for the same price from Midway. Which is the better option?

I had planned on buying an Aero BCG, would that bolt work?1020S-HYR - Criterion Barrels 20" .308 M118 Hybrid Stainless Rifle Length Barrel - AR15Discounts

Including a headspaced bolt usually just means they are selling you a full priced bolt.
How is your velocity on the 185gr juggs? Just picked up 80rds of FGMM for $1.50/rd. Though with the introduction of the 174gr ELD VT i think it will be my go to 30 cal round from now on.
Just buy the entire BCG at one time. Source it from whomever you think is best. Here is a source for the complete TooCraft double ejector BCG. They are very good for the money, probably as good as JP for less than half the price. Swap out the ring and extractor spring with SprinCo.

I've heard a lot of problems with Aero large frame BCGs. What I would (and will, as I'm in the planning stages of an AR308 build myself. See this post) do, is buy the Lantac Enhanced BCG. They're OOS pretty much everywhere at the moment, but they seem to offer better reliability in large frame gassers and may give you a little more accuracy since it's a supported tail carrier.

What is the thermal fit and what would you think about this for a BCG?https://www.armorally.com/shop/toolcraft-ar10-308-double-ejector-bcg/
I assume I could buy just their ambi lower and stick an M5E1 upper on it, right?
I used a Toolkraft (sp) complete bcg, with the nickel coating. I had and continue to have, no problems. YMMV. I think this has been answered now though.
I don't know, through 5 builds I've not had a single issue with Aero large frame bcg's. hell, the torture test went 3600rds of no lube before the firing pin failed. I'd say they are gtgThe same barrel on LWs website *does* come with the bolt

Would you pick the RCA over the toolcraft dual ejector BCG?Krieger and Bartlein are going to be your best of the best. I have 10-12 in the safe in 308 and 6.5cm on multiple MEGA uppers
Headspace bolt for sure, only way I role.
In regards to BCG, I'm a JP or RCA only guy.
The RCA HM coated High Pressure bcg are top of the line.
Little secret, you can buy their 350 398 HP+ BCG for $180 here. They call it their blem, not mechanically but laser engraving, cosmetic they say. Guess what, I've bought tons of these, I've never had one arrive that looked anything different than my non-blems. Same box, nothing wrong with it.
Also, they say backorder. I place an order many times on these blems that say backorder and they all shipped in a few days

You're going to get a lot of opinions. I have gages and I headspace everything. I can't recall the last time I've had one fail the gages. It does happen but generally not with brands you're looking at. If I were building a single rifle, I wouldn't bother. Just shoot it and assess the brass. If you end up building more rifles and need to set HS yourself, buy gages at that time.

So that acts as an adjustable gas block? I had planned on a superlative arms bleed-off gas block. They claim that it does not cause things to sieze. SA gas blockYoull be fine. RCA and JP are widely used bolts companies worth a damn use to headspace their barrels to. I have been personally told this by multiple barrel companies.
Get the RCA blem, you will love it. Top notch lifetime warranty and the HM coating makes cleaning super easy. Slick as snot, wipes right off.
Ill get a step further and also know you can do this later if you dont want to know but its an AWESOME cheap upgrade that can make turing your new custom build even better.
I have used adjustable gas blocks for a LONG time. Was a necessity for me when building any custom AR to fine tune the gas. I have used ALL the top names. They all eventually seize and need replaced or rebuild kits. You can prolong this be cleaning and moving the adjustment screw in both directions after each range session then back to your setting.
Its been a few years since I made the switch on all my AR15 and AR10 builds to Rubber City's adjustable gas key. I fixed low profile regular gas blocks on all my custom builds with the RCA AGK.
RCA Adjustable Gas Key - Welcome to Rubber City Armory
Made from Pre-Hardened 4140: 28-32RC with radiused corners reducing sharp edges. Enhances performance of low mass and standard mass GI systems without unnecessary dissassembly. Gas flow is adjusted and maintained at the carrier with set screws. One to adjust gas flow and one to lock it in place...
It is stupid easy and fast to adjust/tune and works excellent. Zero issues in the 3 years or so Ive been using them and I have them on my AR10 308's, 6.5cm, SBR's, 16" AR's. Zero issues, tune super fast and work great.
You can even place your order and call RCA (great people and great customer service by the way every time Ive talked to them) and ask them to install the adjustable gas key on the blem carrier before they ship it if you would rather they do it....
To tune, you take the tuning screw and screw it all the way into the adjustable gas key until it stops. You then turn it back out 1 full turn. This gets you very close. You then turn it out 1/4 turn at a time to open the gas more or in 1/4 turn at a time to close the gas off more. Once your fully tuned where you want it, you install the lock screw and your done. I set mine where the gas allows my bolt to fully cycle and lock back on an empty mag. I will then go fire a 20-30rd or so, with only 5rds in the mag at a time to ensure every one feeds and the bolt locks back every time. Then lock it down.
I have a Schilen, Proof, Wilson Combat, barrels in AR 308.
The RCA gas key adjustment is another way to restrict gas flow into the carrier. So , yes , it achieves a similar effect.
