I have been thinking about building a lightweight AR for some time. This is my first AR build. I think I am ready to buy the parts. Maybe you folks could steer me in the right direction? I shoot mainly steel targets from 50 - 300 yards. I have a few questions but will hold off until I get some feedback on parts list. Thanks! Main Parts: 2A Balios matched reciever set Geissle Trigger JP Enterprises Bolt Carrier Proof Research 16" Barrel 13.5" v7 hand guard Adjustable gas block  "We've done four already, but now we're steady..." | ||

For the buffer and buffer spring, Swap over to JP enterprises silent capture set up. It is so much nicer and easy to tune to a different caliber if you swap uppers. I don't have any exp with Proof research barrels. I do have some exp with Wilson, baer, and rainier barrels. For the money, rainier is hard to beat. Something like these. https://www.rainierarms.com/ra...ly-barrel-1-7-twist/ https://www.rainierarms.com/ra...un-fluted-barrel-16/ https://www.rainierarms.com/ra...-barrel-18-polished/ Yeah, I know those will way a shit ton more than the proof Research. As for a muzzle brake, I would consider the new shorty brake by Dead Air. Which would allow you to mount any of the Key-mo Capable cans. you can see the shorty on the right side of the muzzle devices. https://www.instagram.com/p/B8MIASNIzOD/ Other than those, I think that is a pretty solid assembly set up. | |||

Holy shit, those are some expensive parts! I'd be hard-pressed to pay $42 for a dust cover assembly. $225 for a brake? Good luck with your build; post pics when done please! __________________ "Owning a handgun doesn't make you armed any more than owning a guitar makes you a musician." -Jeff Cooper | |||

That 16" Ranier Arms fluted barrel is intriguing. It really doesn't weigh that much more, a few ounces at almost half the cost. "We've done four already, but now we're steady..." | |||

Agreed, probably some room for cost vs weight reduction adjustments to be made. I was just trying to get the weight down as much as possible and go from there. "We've done four already, but now we're steady..." | |||

I have a DDM4V1 that has a Vortex Spitfire optic on it. I am considering using that optic on this build for now. It weighs less than the nikon not to mention the mount, and I already own it. I can put that DD back to iron sights. "We've done four already, but now we're steady..." | |||

This is my list from last year when I built my 300black out sbr.   The trigger Is ALG ACT, which is superb for the money. https://algdefense.com/alg-combat-trigger-act.html | |||

Consider an Odinworks handguard. You can save a bunch of money over the magnesium V Seven for the cost of an ounce or 3.

Any reason not to go with a 1-7 twist barrel for my build? I likely will stick with a traditional buffer setup. I thought a 3oz T1 buffer would be adequate with an adjustable gas block. Any reasons to go with a heavier buffer? "We've done four already, but now we're steady..." | |||

That's a lot of money to shave a few ounces here and there. I can see it for a rifle that will be carried miles for hunting, but not for a range toy. Especially the money for the Proof barrel. I have a Proof carbon barrel in my 223 bolt action precision trainer rifle. Nice barrel, great accuracy. I won it in a match -- I sure wouldn't pay for one, however. I consulted with my trusty gunsmith before ordering the Proof barrel. Should I go with a premium AR15 build or a 223 bolt action? My 'smith stated that all the bolt action Proofs they saw in the shop just shot lights out. However, Proof's AR barrels were inconsistent -- some shot really well, others not so much. Slimmer profile barrels with flutes can weigh about the same as a Proof carbon barrel, and they will cost a whole lot less. For what you are likely doing, the accuracy of a quality fluted SS barrel will be equal if not better than that from a Proof. I have a number of Wilson Combat barrels and they all shoot quite accurately. If you plan to shoot enough to burn out barrels, replacing them with Proofs each time will become expensive. By the way, I prefer 1:8 twist barrels over 1:7 twist barrels, but either one will work for most shooters. I do find it odd that you are willing to invest so much into the rifle, yet you choose what must be described as a value-line optic. I sure wouldn't put that Nikon on a rifle that is intended to excel at steel practice/competition. | |||

I will check out Wilson Combat barrels. What do you suggest for an optic? "We've done four already, but now we're steady..." | |||

With an adjustable gas block, you can go with a standard carbine buffer. Just tune the block. That will save you a few dollars. Try a reduced power buffer spring to take the most advantage of that set-up. Bruce "The designer of the gun had clearly not been instructed to beat about the bush. 'Make it evil,' he'd been told.

Take a look at Faxon barrels. I have my eye on this one, to build with an older BCM magnesium rail, that I am switching out for a longer mlok on my primary rifle. https://faxonfirearms.com/14-5...6-nato-4150-nitride/ | |||

16"light weight barrels must be in high demand. Wilson Combat and Ranier 16" fluted barrels are sold out almost everywhere. The proof barrel is not available either unless I got one with 1/8 twist. Any other suggestions for a fairly light weight 16" barrel? "We've done four already, but now we're steady..." | |||

Call rainier. I had only to wait a few days for mine. | |||

I setup alerts to be notified when it's available but I can certainly do that as well. Thank you! "We've done four already, but now we're steady..." | |||

Every 16" 5.56-chambered barrel that WC makes is available for sale at wilsoncombat.com. Why do you feel you need a 1:7 twist barrel? Are you planning to shoot bullets weighing more than 77 grains? | |||

I wouldn't even consider Nikon, as they are exiting the scope business. Consider a LPV scope with 1-6x, or 1-8x, or even 1-10x magnification. Consider whether you want a first focal plane or a second focal plane reticle. Consider the reticle type -- do you want to use a hold-over reticle, which is based on average ballistics for 223 bullets? Or do you want to use a mil/MOA reticle and calculate the exact drops for your load(s)? I like Nightforce scopes, but they are expensive. Vortex is well known in the 3-gun circles for the LPV optics. Vortex prices & models range from value-line to premium. They are a few other brands that work quite well, too. | |||
