So I'm building a 10.5" SBR and I need a barrel. I would like to go with a dimpled barrel to reduce weight and increase cooling. I plan on using a Hornady 55gn V max at about 2840 fps. Does anyone have any suggestions on brand or any input or ideas for parts?

Send whichever barrel you choose to ADCO for dimpling.

Did you mean SBR? As in Short Barreled Rifle?

100% agree on ADCO.

no melonite or any other coating like it. Its too hard to work on and dulls tooling so most wont do it. Get a nice stainless barrel or something of similar hardness.

Ah, yes i did mean SBR, Thanks for the advice. I'll have to look into that, I was looking online for a place that sold them already dimpled. I know KAC has a model with dimpled barrel. Any advice on trigger or buffer system? I'm planning on using a Sig arm brace so its not really gonna be a SBR

I run a KAK tube and a SB15 brace on a couple of pistols.
The buffers just depends on the upper, some just seem to like different weights.
Triggers I like the ALG ACT ($65) for its price it can't be beat.
I also run a SDE and a SD3G Geissele. I like the flat face more than conventional triggers.

I had ADCO recently dimple and refinish my barrel, it came out great!

I don't have any numbers handy, but the crux of the problem is that you have to buy a heavier, stainless steel barrel to dimple in the first place.  On balance, an undimpled CL barrel might serve you better, especially at 10.5".

And I love ADCO, but if you're going the dimple route - it definitely looks cool - also consider Marvin Pitts of Nefarious Arms.  He uses, IMO, a cooler looking dimple pattern in his work.

That dimple barrel looks sick! But I did email ADCO and they did say it would be best to have a heavy barrel AO its gonna cost a bit plus end up heavier anyway. So I think I'm gonna skip that. Thanks for the advice everyone. I'm thinking about buying Sig brace with the KAK buffer tube kit, geiselle SD-C trigger, KNS trigger pins, and a BAD ASS safety. Already have the upper, lower, Aim NiB bolt, BCM gunfighter charging handle, and a Eotech 512. Just need to figure out a barrel and handguard.

Geissele doesn't recommend the Knights pins.

IMHO, adco dimpling looks like crap. You want the dimpling from Marvin at nefarious arms, especially if you already like KAC.
Edit: he can also do it on thinner profile barrels, you don't have to have a heavy barrel.

Marvin Pitts is the way to go, ADCO's barrel dimpling looks cheap, which would match their service.

This is true. Geissele had posted in a thread I created once about this question. The Geissele pin tolerance spec is WAY WAY WAY tighter than KNS.

Marvin's Prices aren't that bad either and IMHO his dimpling looks far superior. And I personally send all my work to ADCO. But if I had to choose dimpling I would say Marvin Pitts! Just google him, he has a Facebook page for his shop.

How much does Marvin charge for dimpling like this???

Thanks for the heads up. I was just about to order both. KNS sells Geissele triggers too.

I think autocorrect got you - Geissele doesn't recommend Kns pins.

And I think Geissele triggers use a different pin retention system than mil spec triggers so the kns pins mess that up as well.  With that being said, my dumb ass used kns pins on 3 of my Geissele triggers for years before I figured out you weren't supposed to.  They all worked and still work fine.  I still use kns pins on those because I think the retention spring thing in the hammer is probably worn out at this point.

Oh I got it. I was just saying I was gonna order both until you said they don't reccomend the KNS pins. I sent Geissele a email asking what was the deal and what they suggest. I might end up getting a different trigger. They are super expensive anyway.

The pistol forum is literally full of all this SigBrace stuff, those boys will be overjoyed to fill you with all kinds of information.  Including barrels and KNS pins.

I agree they are expensive but worth every penny. The trigger is not an area to cheap out on.

Emailed Geissele about the pins. Here is what they said:
The Geissele pins are precision ground and hardened to our specs. We recommend using our pins because we have found that other pins are not properly sized for our triggers and can be made out of a softer metal which may pull up burrs during installation causing the trigger to not perform as designed. If our pins are installed properly and the hammer spring is in the right position, there will not be an issue of the pins walking out of the lower receiver.

So is there any trigger that would be a better value/$ ? If not I think I'll suck it up and get the SD/C. Its only $210 on sale now!
