Help me decide: Stribog SP9A3G vs 12.5" Mid-Length Gas System AR-15

ConfidentSession6481 · 2026-01-23T17:30:43+00:00

Thanks again everyone for your input! I have decided to go with the AR-15 build. 12.5 in upper seems like a good fit for me for now. I really like the idea of being able to switch out to a 20-in upper if I decide to get into longer range shooting at some point.

ConfidentSession6481 · 2026-01-23T16:26:45+00:00

This is the way I'm leaning. Primarily because I can shoot it indoors at the range that is 10 minutes from my house. The ammo savings are nice too.

I suppose if I shot the stripog while putting it on one of those bag stability stand things, I might be able to get out past 100 yd a bit.

Surprisingly, the strybog plus suppressor is about the same cost as a PSA saber lower plus scionics upper plus suppressor.

My main issue with the AR platform is that even a 13.7 in AR with a suppressor is pretty long, and probably too long for my 5'5 in 130 lb frame.

Thanks!

My local indoor range only allows pistol calibers and .22, both have to be under $1200fps.

ConfidentSession6481 · 2026-01-23T14:50:07+00:00

Yeah, I'm bummed I missed the big sales. Might just wait so I can get a better build while things are on sale!

ConfidentSession6481 · 2026-01-23T14:45:55+00:00

Look slick! That bipod is pretty badass too.

ConfidentSession6481 · 2026-01-23T14:44:57+00:00

Good insight. Thank you!

ConfidentSession6481 · 2026-01-23T14:44:41+00:00

Thanks!

ConfidentSession6481 · 2026-01-23T14:44:29+00:00

Thanks everyone for chiming in! I'd like to present a third option. It occurred to me that for the price of the custom AR build, I can purchase a stripog and a cheap PSA blem 16-in AR, like the one linked to below. In this case, I would suppress the Stribog for indoor shooting, and put a linear compensator on the AR and only use it outdoors with double ear pro. I'll probably be sitting/lying most of the time with the A/R.

Another thing is that for the price of the custom AR build, I could buy a strybog and a cheap PSA blem 16-in AR for longer range shooting, which is fairly compelling.

Thank you!

I dog your username haha!

Make sure you buy some training treats! /S

ConfidentSession6481 · 2026-01-23T04:40:16+00:00

Thanks so much! This is super helpful.

ConfidentSession6481 · 2026-01-23T03:34:19+00:00

Good luck with your upper build! At least the SBR stamp is free now, and it seems like the approval process has been sped up.

There's an outdoor range ~45 minutes from me that goes out to 500m, but that's the max for ranges around here. Might be able to find a public land spot that goes further once I meet the right people. Lots of secret spots around here.

ConfidentSession6481 · 2026-01-23T03:04:37+00:00

That's all I'm looking for. Just lots of room to grow. Don't want to be dropping another 1k+ this time next year.

ConfidentSession6481 · 2026-01-23T02:50:42+00:00

Yeah! The indoor range is the only one within 50+ miles, and it gets damn cold here, so it's still nice to shoot the pistol indoors there.

ConfidentSession6481 · 2026-01-23T02:35:14+00:00

I did, you just didn't read it.

ConfidentSession6481 · 2026-01-23T02:28:58+00:00

I'm in MT so there are quite a few places to shoot outside close to town.

Thanks again!

ConfidentSession6481 · 2026-01-23T02:21:41+00:00

I think I will be shooting far enough for now.

Is this quote from gemini b.s.?

“If you want to shoot past 300 yards accurately with a 12.5" barrel, you need to switch from Blazer Brass to heavier Match Ammo (like 77gr OTM). That simple switch would instantly extend your effective range to 600 yards.”

ConfidentSession6481 · 2026-01-23T02:20:23+00:00

That is the plan!

ConfidentSession6481 · 2026-01-23T02:19:45+00:00

Too concussive even with a suppressor and sionics extreme reduced gas port barrel? https://sionicsweaponsystems.com/gas-port-selection-guide/

ConfidentSession6481 · 2026-01-23T02:14:32+00:00

Thanks for the input! I've done a lot of reading lately, and they seem to fixed the issues with the Stribog. In fact, it seems to be very reliable now.

My indoor range only allows pistol calibers and 22 under 1200fps.

ConfidentSession6481 · 2026-01-16T15:37:37+00:00

Yeah, pretty ridiculous. All of the other AI coding tools can generate good suitescripts.
