Default Second AR Build? Opinions and Ideas Welcome

So I am looking into building a second ar (first one is a carbine) and was thinking about making a long range ar. However, after research, it seems like I should just go up to a 308 if I plan on reaching out to 600+ yards.

What other kind of ar's are out there? I have stripped lower so I can't build a pistol out of it.

SPR?

Etc.?

Thanks,

Ever consider a rifle length, 20" barrel?

Yeah I was going to go 20" SS bull barrel and make a long range shooter but how far can a .223 go without holding over 10 feet?

There are plenty to consider for a small frame AR...

Alternate calibers like the 6.5 Grendel is a popular choice if you want something for longer range shooting. The available bullets with better BCs make for a nice target shooting setup in the same frame.

18” – 20” heavy match barrels would also make a nice shooter in a .223 or you can do something along the likes of an SPR clone.

Either way, if you want to get into shooting at longer ranges, be prepared to buy or load your own match ammo. Without it you probably won’t accomplish much more than what you can already do with your existing carbine.

The great thing about the AR is there are thousands of different variants you could build. You could just pick a general theme/usage and go from there. You could build a competition 3 gun type build. You could build an SPR. You could build a Recce rifle and get the best of both worlds. You could build a battle rifle. You name it, you could do it.

Right now I have two carbine type run-n-gun CQB rifles. I went with the "two is one, and one is none approach". The upside being I have two of basically the same rifle so that if one is down I can just pick up the other one and run with it. Also if a friend or relative wants to take a course with me they don't need to own their own rifle. They can use my backup. The downside being that I have a lot of money invested in two rifles that do the same thing when I could have two different rifles meant for two different rolls.

My 3rd rifle is still under construction. I am thinking SPR, but might go 3-gun. It has a CMC drop-in match grade trigger in it. So it won't be another CQB. You don't want a hair trigger in CQB gun...to dangerous. I'm in no hurry to finish this one. When I have extra cash I buy a part. But right now I am focused on buying a house.

I've built a ton of different rifles over the years. The one I hang onto is always the CQB rifle. It's my favorite. But building the other types is loads of fun.

Build an upper in a different caliber... You have many choices. My current project is a 7.62x39. Many people frown at that round in an AR but if you do your homework and get good parts (key here is bolt and magazines) it can be done. I've shot an AR in 7.62x39 and it was a blast to shoot and it was reliable. You can do 300blk, 6.5, or go big with your small frame lower and do a 458 socom or a .50 Beowulf. Going big is expensive which is why I chose the 7.62 route. Plus, I have ammo already from my Saiga so it made sense (to me)

build something with a 18" match barrel and good trigger. With good ammo that should get you to 600+.

I shoot 75’s out of my 20” 223 and it’s a real hoot shooting 500-700 yards with it.

Elevation is easy to dial in and gives me good practice on making those wind calls.

And to your reference of holding over 10 feet... that's pretty much what my dope is at around 600 yards with my 75gr 223 load... -122" of drop, just under 20 MOA.

As a comparison, my 168gr 308 load shooting out of my 20" barrel, my drop is around -115"

A lot closer than most people think it would be... dialing in 20 MOA of drop isn't a big deal, making those wind calls is what counts.

I concur with going to one of the other small frame calibers. I built two basically identical .223 Wylde chambered ar's, and one "beater". With the other three that I have, I'm going with the 6.8spc cartridge. Two fancy tacticool ones for me and one "beater" that can go to the range with me when co-workers want to shoot an one. That way I still have backups if anything goes wrong with the primary ones.

SRP MK12 Mod 0 rifles look nice

AR9/45 for cheaper ammo

I have assembled three ARs and am working on my fourth. My long distance AR is a 20" in 6mm Fat Rat.

308 is too expensive especially for shooting paper.

that's what I did... with a Geissele SSA-E trigger and Mako SSR-25 stock... after a carbine and 3 mids, I figured a rifle length semi-precision would be fun.
