A Faxon pencil barrel is about $270. ADCO will turn down a barrel for $120. If I were in your shoes, I would start by having my existing barrel turned down. If that didn't solve the problem, I would go with a lighter BCG and an adjustable gas block. Next, would be a lighter handguard and stock. You might solve your problem with $120, so that's where I would start.
ETA: I see where you just want to use the .308 AR for deer hunting. Just use the bolt gun, and call it a day. |

ADCO will turn down a bbl, Paladin Machining of SC will make a bbl from a blank & a bbl extension - who will nitride a bbl & extension?

Quote HistoryQuoted: I ventured into this not too long ago. Carbon fiber barrel, titanium BCG, titanium parts (they add up to save weight), lightweight handguard. The one I built was well balanced, but the money involved didn't really make it a game changer necessarily. Quote HistoryQuoted: I ventured into this not too long ago.

Compare the FAL bbl and piston to an AR gas tube and bbl w/o the bbl extension. |

They are light but have a lot of QC problems. Some catastrophic. |

Compare the FAL bbl and piston to an AR gas tube and bbl w/o the bbl extension. You're right. The FAL rcvr prob weighs 2-3 times as much as LR308 upper. |

Proof Research. If you get a good deal, you can get into one for a little over 700 bucks. They are damn nice.

Quote HistoryQuoted: By the time you are done reprofiling or replacing the barrel, shaving lightening cuts into the receivers, messing with the bolt carrier (a significant portion of the weight), and everything else, you're into new rifle money. At that point, maybe consider getting a POF Revolution DI or Rogue. https://cdn.athlonoutdoors.com/wp-content/uploads/sites/8/2020/01/POF-Rogue.jpg You could also build or buy a 2A Armament Xanthos XLR. https://cdn3.volusion.com/aecne.wevxc/v/vspfiles/photos/2A-XRC20SC15CAM-2-2.jpg Or you can go to town on the DPMS with an end mill, get a Faxon pencil barrel, Titanium parts, lo-mass BCG, adjustable gas, increased spring weight, carbon fiber handguard, skeleton stock, etc. It's only money... Ooohhh. I had no idea those POF rifles existed. |
