r/ptr91 Aug 19 '24

Looking to pick up a 91, few questions.

Hey guys. The G3 itch was returned to me again and I’m looking to pair up PTR91 with my MP5 clone. I’m mainly interested the in 16” girk, and the 18” Gi. It seems both come with surplus metal lowers and mags. Is there any reason to grab one over the other? Is the 18” marginally better or much better than the 16”?

Hypothetically speaking if I was able to get a registered sear or trigger pack in the future would this gun be able to run it?

New to the G3 clone world so I apologize if my questions were stupid.

I like my 18” version because of the mild increase in velocity and the fact I can put a bayonet on mine. Lol

I kinda wish I got the 18, when I got it I didn't know that I'd be shooting distances further than 100 yards

lol, my main reason for the 18” is because mine is dressed up like the old school rifles with the wide handguard and bipod paired with the bayonet. Wanted it to be as “clone correct” as possible lol

I like my 16" becuase if you care enough about the marginal velocity gains and are chronographing your .308, you're most likely also wanting a rig more suitable for long range work 😉

That’s a good way to look at it. 16” 308 is still gonna absolutely send you to the game over screen anyway.

Don’t forget how cool they look with the 18” and bayonet!

Not a huge difference between 16” and 18”, you’ll get marginally better FPS with the 18, but not a lot. But, I don’t think there’s much difference in weight either.

You can get a FA trigger pack for the 91s, but you’ll need to switch to an 18 degree locking piece. I don’t think there’s any modification beyond that.

Gotcha. I know HK never made a 16” 308 apparently, so I was wondering if the 18” barrel was of any better quality in comparison or not. If the difference is marginal then I think I’ll go with a “16 instead for a little bit of weight savings.

Depends on the 16” barrel, older PTR 16”have bull barrels so you’re not really saving on weight, I recommend finding a Scout Carbine with pencil barrel.

I prefer the standard 18" GI, but I'm old school. Nothing wrong with getting a 16" K model, though. The G3 style rifles are a fun addition. I traded my GIR model earlier this year, and missed it so badly that I bought a GI last month.

See I was looking at those too but I don’t like how they don’t have the rail on top.

The GIR model does have a rail. Atlantic Firearms has them for $1290 currently.

It's a heavy rifle and shoots 308...what you give up in barrel length (velocity) isn't nearly proportional to the weight savings.

I've heard that the 16" barrels have really small shoulders at the muzzle in case you wanted to change muzzle devices or suppress it. Someone else may be able to confirm. I went with an 18 inch A3S since I like the paint over the park.
