View Full Version : I’m considering my first pistol, that may become an SBR.
Looking at a few directions. Optic will be Sparc 2, or possibly Aimpoint PRO in the future. Trigger will be Hiperfire 24C. Laws will be followed in regards to intent/building order, etc.
1. 8-11” 7.62x39. I have a 16”, so mags etc. are there. Would probably transfer parts (Syrac Ordinance adjustable gas block, LMT bolt and Tactical Ambush carrier, maybe handguard) and sell the 16” if I went this route. 10.5" length should allow VFG as a firearm.
a. Buy different barrel and transfer parts
b. Buy different upper and transfer parts
2. 4-9” 9mm. Don’t own a Glock, so I am on the fence as to Glock or Colt pattern lower, and dedicated or mag adapted lower.
3. Short 5.56. Just got into the caliber, so don't have much knowledge about running one.
4. Short 5.7. At bottom of list because I want one, but I don't think it could do anything better than the others, aside from capacity, and probably better for small game use. RDS would be fine with no real rail space.
Ammo is not a worry. Best for short barrel suggestions would be great.
Can anyone offer opinions or thoughts as to which way to lean?
Use will be range toy, walk about/hunting pistol, and possible travel to big city vehicle carry.
No other calibers are currently in consideration.
Of your choices, I'd go with 11" 5.56, followed by a shorter 9mm.
My top choice would be an 8-9" .300 BLK, but that wasn't on your list.

THIS... Though the 11.5" 5.56 would be my second choice. Is there a reason you don't have a 300BLK listed?
Another vote on the 9-11" .300 BO
I can only assume the OP is committed to the 7.62x39 and the .300 is too close to justify adding another caliber. To that I'd suggest dumping the 7.62x39 getting a .300 BO, already having something in 5.56 so your covered there for now, next figure which AR lower that accepts Glock mags you want to go with for a near future project.
Wait wait wait, never mind, that's my plan.

Overall ammo availability, already purchased ammo (8m3, 8HP, SSTs, etc.), 25 years of shooting it, $/rd. superiority of commercially available supersonic hunting ammo, and no widely available subsonic hunting ammo for .300 that gives enough confidence to use on medium game vs. x39.

I have considered dumping the x39, but only for a 6.5 Grendel. But again, with hunting in Central TX and KY at 25-150 yard ranges, the 6.5G doesn't do much.

Roger that... My vote is to then go with an 11.5 5.56 pistol to SBR plan. Easiest upper to flip if you decide you're not a fan, and IMHO the perfect length for an SBR 5.56. Do you plan on hunting with this gun, or just keeping the option open?

I hate to pile on, but I too would go with 300 blk. However, this last sentence confused me. There is no widely available x39 subs period, much less suitable for medium game.
However, if you are dead set against it, then a 11.5" 5.56 is my next choice.

If I already have the "same" in a rifle length, I'm not sure.
I was only considering the 9mm or the x39 because the shorter barrel wouldn't be as much of hindrance. The 5.7 with the small case should probably be the same.
Asking out of ignorance, as I mentioned in my first post, I'm not sure what kind of velocity hit I am looking at going from a 18" 1:8 Wylde with rifle gas to 11.5". I've got 55-75 grain ammo.
Honestly my main recommendation would just be to make your first SBR a standard AR lower regardless of the caliber you choose to get it in. This will just give you the most options down the road for your tax stamp.
That being said, of the options on your list I would personally go with a 10.5" 5.56 with an adjustable gas block or an 11.5" one if you don't want an adjustable gas block.
300 Blk. Otherwise I agree with Plinker - just pick up a quality lower and do a form 1 on it. Now you can do 300 Blk, 556, and 9mm in any config you desire in any upper.
SBR a 10.5" or 11.5" 5.56mm AR. If you're already into 7.62x39 and just got into 5.56, I would not add yet another caliber in 300 BO unless you're planning on reloading.
If you want to go pistol caliber, I would recommend a MKE mp5-n, MKE mp5k-n, or B&T APC9.
Since you're considering dedicated lowers, versatility seems a non issue, so... I'd say if you want 7.62x39, go with an ak sbr.
I don't know ky hunting laws, but make sure you're within regs before going nfa for that purpose.
Starting from scratch I'd go 300blk. Actually, ime, it costs more to try to fit around stuff, so I'd still suggest a 300blk in 8-9", or 555 11.5".
Subs and pistol ammo give up a lot in terminal ballistics. If I wanted to run subs only, I'd go 9mm, as I havnt seen a lot of 300blk good subs out yet. Even if they come out, it's going to be a really good pistol caliber with better reach when you get down to it.

I have some 115s for the pistol, but a good amount of 147 fmj and hp. Plan for the 9 was always subs. We will probably never see .300 subs near the price of 9mm subs. Just don't know if I should stay 4.5" or go 7 or 9".
Unsuppressed range toy? I would just shoot a 16" gun. Save $200. Save cheekweld.

This, especially if you even remotely plan to suppress it in the future.

5.56 is what I did.

Oh, I must have missed it. I was assuming a supressor was going on.
If I did 9mm, it would be 4-5" bbl. No silencer changes things. I'd go sbr 762 ak or 223 11.5"ar, especially being a potential hunting gun.
If I were to do a SBR from a pistol today, Id form 1 the nickel plated PAP pistol from atlantic firearms and get a reputable builder to convert it to a triangle side folder, which I would also have nickel plated to match the rest of the gun. Slap an afghan braided goat hair sling on it and youre ready for action.

I have a blast with my 9mm. And Ammo is always plentiful.

No suppressor: 11.5" 5.56
Suppressor but not reloading: 11.5" 5.56
Suppressor and reloading: 8-9" 300 blackout.
I personally wouldn't go 9mm in a dedicated AR platform (unless you already owned Glocks). I would go Scorpion Evo, Sig MPX, or MP5 clone (in that order).

I do not own a 9mm AR or a Scorpion Evo, but I have a SBR MPX and picked-up my MKE Z5P today from my FFL - function checking that little beeatch begins tomorrow. Let me just say a brief word or two about the MPX. It's a very easy gun to shoot and very well thought out in terms of controls with ambi everything. I've had no complaints in terms of accuracy or function. It is a bit hefty and thick at the handguard. BUT, that handguard will accomidate a 1.5" diameter can and still allow full use of the Keymod rails.
My only bitch is with the tapered barrel shoulder. Who the hell does that? It basically eliminates half of the 3-lug muzzle devices since they will index on the shoulder rather than the crown. The Gemtech and TROS seem to work properly, but this could have definitely been executed better.
I have a 16" 9MM AR, two 556 SBR's, a 11.5" 556 pistol, and a 300BO (currently a pistol).
I have suppressors and I reload. For what you want I would do a 300BO pistol and put the $200 tax stamp towards a 762 can. Further, I suggest you buy the can first. After a trip or two to the range shooting rifles with the can, you will not want to shoot a rifle without one. As the barrels get short the value of the can just goes up.
The 9MM AR is a fun toy. But it would be at the bottom of my semi autos in a more serious role. The 556's (SBR's and the pistol) offer special roles. But if I had to pick just one, I would give up the range and take the 300BO.
I hate to pile on, but I too would go with 300 blk. However, this last sentence confused me. There is no widely available x39 subs period, much less suitable for medium game.
However, if you are dead set against it, then a 11.5" 5.56 is my next choice.
Yes, therefore I have no reason to shoot either subsonic in a hunting situation.
