AR Build

[lokidog]

OK, getting the lower figured out and I can't stop....  Just a side note, I will not be putting thousands of rounds through this gun.  I will likely be shooting whatever is the cheapest ammo, 55 and 62 grain.

I've found these components, any feedback on brands or other?

Barrel - Radical Firearms 16" mid-length melonite or 16" M4 profile phosphate, both are 1:7  $102
BCG - PTAC 5.56 Full Auto Nickel Boron BCG $90
Upper - Anderson assembled incl. charging handle and gas tube  $103

or Stripped Upper Receiver & BCG Kit (Bushmaster) $119

Thx

That's a good deal on the BCG with nickel boron, as far as Anderson components, they are cheap but well made. I have put a few of their lowers together and they are all in spec. Keep in mind these were $45 lowers! The parent company produces aerospace parts if I remember correctly.
 Never heard of Radical Arms, but man that is cheap.

Looks like they're all pretty solid parts. I couldn't see many negative reviews really.

Thanks, how about the barrels?  I don't know what melonite is, guess I should do an internet search.   

Looks like melonite might be the better one?

The barrel a friend of mine is getting for his build is Black hole Weaponry out of St. Helen's OR. It's a bit pricier and it'll have a muzzle break on it, too.

Melinite is supposed to be more accurate but less durable. Also harder to re-throat/rechamber if I understand correctly.

Thanks, I don't think I'll shoot enough to wear out the chamber though.

Welcome.

I've never heard of anyone setting an AR barrel back. You would have to remove the barrel extension and re-thread and then the gasport and gasblock shoulder would need a modified gastube.

Melonite/nitride is a relatively cheap process when done in quantity and at the end of the day is just hype.

Shoot 'em like you stole 'em.

OK, so I think these are my two barrel alternatives.  Are there any issues to be aware of with the carbine vs. mid-length gas system?

Also, I've seen mixed reviews of the PTAC BCG, though the negative reviews seem to be older ones, any thoughts?

Thanks y'all.

Mod 1 , has just about doubled their prices over the last 3 years.

Thanks guys, how about carbine vs mid-length gas system on a 16" barrel?

I guess that's why my 204 complete bull barrel upper was spendy. I just found them last year........
