Buffer tubes, buffers and springs

[NATEWA]

I just placed an order and now thinking "did I order the correct parts?"

I'm putting together an ar308 and here is what I got and just ordered.

Ace Skeleton Stock
DPMS A2 308 Buffer
AR 308 Rifle Length Spring

I have a DPMS bcg and barrel. The barrel is a rifle length gas system. I also have an adjustable gas block.

Correct set up? Is there a sticky or online resource for proper lengths, springs, buffers?

Thanks

Seems right.
You need a rifle-length 308 buffer and a rifle length 308 spring to use with a standard AR-15 rifle length receiver extension that is used by the ACE stock.

Thanks Randall. This is my first build and I'm ignorant about a lot of things in regards to the ar308. Could you please answer a couple of questions for me?

I ordered this handguard.

Will this barrel nut work?

One more question. I have a dpms bcg with no forward assist groves. I bought a forward assist knob and spring to put in my aero m5 upper to fill the hole. I understand it won't assist the bcg to go forward. I read somewhere a forward assist is not necessary for a 308. Is this true?

Thanks again.

the tube comes with a nut.

And forward assist is not needed on any properly functioning rifle but if it fails to go home.... then you would need a forward assist

I just read the description and see that it comes with a barrel nut. It must be inside the handguard because I don't remember a seperate part. I'm going to go look at it now. Sorry to be dumb about this. I was watching a Brownells video on how to install a barrel and saw them install the barrel nut and thought "I didn't order one."

Thanks
