Sitting here looking at my rifles, and one of them is really sticking out to me.  It's an SPRish 18" AR in 556.  I haven't shot it in a while and I need to get a scope for it.  I guess I've just been shooting my other rifles which are SBR's.  I know it's ultimately my choice, but trying to figure what to do with it.  I could sell the upper and build something else with the lower, sell the whole thing, or just keep it.  Here's what I currently have:

5.5" 22 upper
5" AR9 SBR
8.2" SBR 300blk
10.3" SBR 556 (wife's)
10.5" SBR 556
13" SBR 556

I also have a 10.5" SCAR16, 13" SCAR17, and a 10" PAP M92 AK.

I've thought about building a 6.5/6.8 and maybe a 458 SOCOM, but have considered just doing uppers on those and making them around 12.5" so I couldn't use them on the SPR lower since it's not an SBR.  Suggestions??

Nope...haven't shot them in years.  

The only non SBR I have is an SR-15 mod 2, which does get action on the regular.

some.

only non NFA rifle I have (MSR) is my Arsenal SLR-107.

everything else is 10.5 - 14.5"

I never shoot my full size guns. Debating selling my n-pap. I have an SBRd M85 and a Draco that is about to get a stamp.

My 18" get shot at distance quite a bit, yes.  A longer heavier gun is also nicer for groups.

Ostensibly, my 18" 5.56 AR is my mid-range, less expensive alternative to my 6.5 Creedmoor with a 24" heavy barrel.  The Creedmoor is great at distance, but it's mostly overkill for tannerite or steel at anything less than 200.  Because the 18" 5.56 is a bench/prone gun that wears a bipod, I don't mind the weight or length with the can attached.  That said, I still don't shoot the 18" that much because the Creedmoor is more fun to shoot, even if I am burning a quarter or more per shot.  I'm on the fence about what to do with this gun.

The other non-SBR AR was a 16" lightweight Noveske 5.56.  With irons and an A2 flashhider, it was a nice, handy gun.  However, after the addition of a QD can, even the lightweight titanium version still felt like a brick hanging off the end of the barrel.  I considered going the 10.5" or 11".5 5.56 route and SBRing that one, too, but my Blackout felt too long at 10.2" (I had it shortened), so I knew I wouldn't be happy with even a 10.5".  A 7.5 5.56 would be really fun for plinking, but YHM doesn't warranty the can for that short a barrel in 5.56.  I already have guns in 7.62x39, so that wasn't an appealing caliber for an AR SBR.  

Although I looked at them and ruled them out a few years ago because cheap, milsurp ammo dried up, I stumbled across an old thread on running 7.62x25 Tokarev in an AR upper.  Although the price per shot is slightly higher than 5.56, it's less than Blackout, so that's a plus.  I can still use the same .30 cal can that I run on all my other rifles.  Additionally, I figured that I could run an even shorter barrel than the Blackout and have no issues with the suppressor blast baffle wear.  Finally, though it shoots pretty darned flat to 100 yards for a pistol, the velocity is still low enough that even at fairly short range it won't eat up my target steel like the 5.56 does at distances less than about 75 yards.  I took the plunge and sent some parts to Tim at Heavy Metal to have a 7" Tok upper made to run factory ammo.  Though the 7.62x25 can be throated to run longer, heavier bullets at subsonic speeds, like the JD Jones 7.62 Mini Whisper, I decided to stick with supersonic factory ammo for the sake of plinking.  It's still a work in progress as "custom" takes time, but I can't wait to get it to the range and ring steel with it.

i'm in the same boat (except i've only been in the NFA game for about a year). the 16" SS BCM came out once for shooting groups, but other than that it's been entirely SBRs.

 

16" recce

Building a 18" SPR

Builidng a pinned 14.5" .308

I can't remember the last time I shot a 16" gun but it has been at least a couple of years.

I shoot my work AR (A2 with a 16" HBAR, soon to be swapped with 6920 uppers with an Eotech) when I have to, which is 3 times a year for quals. I rarely shoot my 6920, but shoot my 10.5 monthly at least. My 6920 is set up with a Leupold MarkAR MOD1 1.5-4, so it's not so much a CQB tool, and not as fun as my SBR.

I finally pulled out my pinned 14.5 KISS rifle last weekend, my 11.5 sees the most action these days. I have a 16" middy all decked out with a 13" KMR, B5 Sopmod stock, MBUS (did have a PRO but it got moved to the 11.5) and painted in sponge camo. I can't remeber the last time I've shot it. I've been thinking about selling the KMR, picking up a 10.5 or 7.5 barrel and new bolt or keeping the KMR and just doing a 14.5 barrel and new bolt. I'm still not exactly sure what I'll do yet but I can promise that the 16" barrel will be going bye bye soon.

Have not touched my 16" barrel since i got my 10.3" and built my Mk18

Yes, I still shoot my title-1 guns despite having more SBRs than title-1s.

I have a 22LR that I shoot regularly that is 16".  Once my suppressor stamp arrives I doubt I'll use it much.   The only 5.56 AR uppers I shoot anymore are SBRs.  I'll keep my other uppers for out of state use as well as sentimental reasons.

Nope.

Do it!

My 11.5" 6.5 Grendel is the most fun to shoot out of all my ARs. It's cool how much "thump" comes out of such a small package -- after the first shot you know you're not shooting 5.56. As an added bonus, the BHW barrel is capable of good accuracy: I regularly see 1 - 1.5 MOA off the bench using Hornady 123gr Grendel ammo.

I've now got my collection to SBRs and a precision dedicated rig. I don't care to shoot anything in between.

favorite non-SBR is a 20" A4 setup with ACOG.  opposite ends of spectrum

Can't remember the last time I shot a rifle that was not a sbr

I have two uppers that I use with the same lower, but both for Civilian Service Rifle matches. A 20" Hbar with a March 1-10x24 that I use past 300 yds, and a 12.5" medium weight barrelled one with a 1.25-4x VX-R Patrol that I use from 300 yds down to 25yards. Ticks all my boxes...

I sold my non SBR rifles.  Just have a shotty and SBRs or projects becoming SBRs.

Not nearly as much as my SBRs, other than my .308 bench AR.

no sbr ... :(

Yep, I shoot my 18" and 16" 10 times as much as my SBR.  But those are both 3 gun rifles.

in 5.56 its either my AR SBRs or 16" bullpups...

shoot .308 and 7.62x39 often, no SBRs there...

AKs? No. I find myself shooting only my 12" AMD-65 SBR. But my non-NFA ARs see regular use. I have a few 14" 556 ARs with permanently attached YHM Brakes and ACOGs mounted on each. I enjoy shooting them as much as my NFA ARs.

Then there's the 20" 1:8" upper I built using an Olympic Target barrel. With 75gr TAP it shoots 1/2" 3-shot groups at 100 yards. I've been enjoying that upper even more than my SBRs lately.
