where my ptr 91 homies at?
i'm getting ready to pull the trigger on a PTR 91 and need some help:
Apparently the newer version of the PTR91 has a different cut of the flutes in the chamber and/or less or more flutes (11 vs 12 or vice versa) to address the extraction problems that the "old" flute cut had with sealed ammo. Apparently the new cut does not hold the spent casing so tightly.
also i understand - is this right or wrong - the PTR91 GI has this more forgiving chamber so it is less finicky with ammo? or is the GI another step different from the other PTR versions somehow?
I would prefer a PTR with an aluminum hand guard so i can put on a couple rails and a decent bipod (not barrel mounted) but there are some good deals on the GI so perhaps oi get it and just buy an aftermarket handguard.
am i correct in thinking that if a PTR91 has the paddle mag release that it is the newest version of PTR in its series and it will have the "better" flute cut, i.e. less finicky?
pic is an older version of the PTR without paddle mag release.
also i donut want to mess around with drilling/machining an older version into a paddle mag release version.

Yep.

Yep.

Paddles were introduced one or two years after the fixed fluting rolled out. Every paddle release model will have proper fluting.

thank you kindly. How can I tell, on a model with no paddle release, if it has the fixed fluting? is there one less or more flutes?
i am finding mixed info on this lurking around on other boards; some discussions say there is one less flute and some say one more and some are saying the same number just a different cut.
i probably will not bother with a ptr91 without the paddle release but was jw.
also is there any difference in the chamber between a new GI and, say, a new FR/SC/KFM4R?
>>
>>31059235
Dunno how to tell, IIRC the cut is deeper. Contact PTR, they could probably tell you.
>is there any difference in the chamber between a new GI and, say, a new FR/SC/KFM4R
No chamber difference, but FR/SC/KF series have a bull barrel for target shooting instead of the thinner military barrel profile.

perfect, dood. ty.
i wasnt really clear on the barrel thickness from the site description, it does say tapered but still says match, helpful to know its thinner on the GI.

The flutes haven't been an issue for years. If I remember right the bad chambers had 10 shallower flutes while the good ones have 12. I could be wrong on that.

While we're here I guess I'll post mine. Green is in vogue it seems.

I'm pretty sure the fluting issue was resolved in 2011; all the rifles, whether heavy-barreled "F" models or pencil-dick "GI" have the same fluting as a real G3. All of the models made at Aynor will have the better, HK-spec fluting.
You can mount a bi-pod on the slim handguard by just drilling though the center of one of the heat shield rivets and screwing a detachable sling-swivel stud into it. Or you can get a wide handguard and an HK bipod while RTG Parts still has them for cheap.

I got a new production PTR 91 back in April. Came with paddle release, optic rail, steel receiver etc. I've never had a single problem with extraction or feeding. I haven't had one jam and I've put a lot of different ammo through it, probably close to 650 rounds now.

Get an AR10 with the worst BCG you can find, then tape a 5lb dumbbell to it, and you will have a PTR91

This guy's has perfect trigger control.
I fucking wish I didn't live in such a communist state, if I could buy a PTR91 I would right now. Gonna have to stick to M1As for now.

Anyone try a brake on their ptr to try and mitigate recoil?
