I decided I wanted something I could use for Elk season. Want to keep it light so going with 18 inch barrel.
What I have so far Quentin D anodized 308 lower dpms a3 flattop upper low profile w FA and DC Interested in: dpms sass 308 18" barrel w micro .963 gas block RRA 2stage trigger MI keymod 15" ergo grip magpul str or ctr stock dpms panther muzzle break also need: LPK buffer tube and spring sights or scope mid length gas tube anything else I am forgetting? Suggestions on parts? thanks |

The DPMS SASS barrel is heavy. I would not want to do a lot of hiking for fun with a rifle built with one. I have a DPMS SASS and its the heaviest semi auto rifle I own. It may be even heavier then my 26" bolt action rifle but I have never weighed the bolt action w/scope to be sure.
AIM surplus has a 18" barrel listed for I think $140 right now. I do not know anything about the maker but might be worth looking at it. Also look at Rainier Arms barrels. |

I assume you are building a stalking gun for quick/snap shots within 100m, right? Otherwise you would be going with a bolt action. I have a carbine I built for the same purpose and I used this:
link No need to lug around a bull barrel for boiler room shots on elk at that range. Just my 2c; ymmv. Good luck with your build. |

Went with a Faxon 18" SS heavy fluted weight is 2.31 lbs only 2 ounces more than your 16" rainier armalite.... yes that sass is alot more than what I wanted for sure. |

| I know PSA has gotten a lot of flak over their PA10 and what parts are proprietary but their BCG is dpms pattern, has FA serrations, worked good on my Maten with rainier match barrel and is in stock. It was tight when first out together, but passed a go gauge and after clean, lube, and break in it's been great. Machine work looked excellent, coating was even. If rather have em on the right side than the loose side. Just a recommendation if you get it a time crunch. |

What I have so far Quentin D anodized 308 lower dpms a3 flattop upper low profile w FA and DC Interested in: dpms sass 308 18" barrel w micro .963 gas block Way too heavy for a hunter RRA 2stage trigger Don't get this trigger. There are much better options for a hunter. A simple tuned rack trigger or drop-in single stage trigger is what I prefer. MI keymod 15" ergo grip magpul str or ctr stock dpms panther muzzle break make sure you know what a .308 with brake will sound like, and reconsider whether you want that kind of blast. For hog-hunting on multiple targets, they are awesome, if you put electronic muffs on before you start slaying. For stalking hunts on elk, where chance contact is common, a brake isn't much fun. also need: LPK buffer tube and spring sights or scope mid length gas tube anything else I am forgetting? Suggestions on parts? thanks I would get the lightest barrel from the most reputable manufacturer possible, with a chamber leaning on the generous side for the case body and neck, and throat length ideal for your intended loads. The DPMS SASS barrel is a heavy beast meant for precision shooting from the prone/bipod, not carrying around while hunting. Trust me, they are exceptionally heavy. You want a light or medium-light barrel profile. 18" is a good length. I would start this by looking at what load is going to be suitable for Elk. For me, that means the Hornady 150gr GMX Superformance factory load. Hornady 150gr GMX Superformance Because of the medium-slow burning powder, I would prefer a rifle-length gas system, and seal it well at the gas block and tube. For these reasons, I would go with a Fulton Armory 18" RLGS lightweight Criterion barrel. They are very accurate, well-made, and priced just right. Fulton LW 18" RLGS You should be cranking the 150gr GMX out at around 2750-2790fps, which is more than adequate for Elk. It will blow right through them and expands rapidly, without losing any weight other than the polymer tip. You're looking at 99% weight retention. The MI KM handguard is great, however, I would also consider a carbon fiber tube. Just don't grab onto a metal tube in the cold after you have dressed out with bloody hands. A friend of mine pulled the skin off his hand that way. I don't know what pin length and diameters will be compatibly with the Quentin D lower, so you will have to navigate that aspect yourself, or with the help from others who have them. For BCG's, I would go with one of these: JP Lo-Mass with high pressure bolt and firing pin AP Customs/Rhino Lo-mass BCG Rubber City Armory fluted carrier and high pressure bolt, black nitrided For recoil systems, I would go with the JP Silent Captured Spring system and balance it out with your gas system and BCG for optimum cycling. The 18"/RLGS will help you out with that. With all that said, I've been down the .308 AR road and got away from it because of 6.5mm. I currently have a .260 Remington AR on DPMS receivers (basically a 6.5-08), and several 6.5 Grendel AR15's. A lightweight .308 18" AR will be plenty for elk hunting, but you will need to pay attention to parts selection as you work to keep the gun light. A lightweight barrel and handguard will go a long way to making that happen for you. For a scope mount, I would go with Aero precision or NightForce for the lightweight mounts, and get appropriate glass for Elk hunting, where you aren't worried about target knobs getting accidentally turned, glass is clear, quality brand with a solid reputation, great low-light gathering capability, and the ability to hold up to .308 AR recoil and return-to battery shock on the tube. Leupold Vari X's are good for that, at good price points. Most importantly, get out and get some training on making hits in the field, in field conditions, at UKD targets with Elk vitals in mind. |

just built a recoil system on my 308... A5 vltor tube, regular H2 buffer, 308 length recoil spring. The key to all of it is the adjustable gas block. Ive got an SLR rifleworks that is key when shooting it suppressed. FYI, this is a 16" Rainier Match barrel. Thanks ill check them out I ordered a geissele g2s for $150 today too |
