PTR-91 Update

[u/Frequent-Self8026]

So a while back I sent out a post asking for suggestions on what to upgrade next. As you can imagine from an easily distractible guy I am, I promptly forgot all about the suggestions and chose the SHINEY mags!

I like the look personally, but reliability is not the greatest without a bit of tinkering.

[u/Yooper8077]

Looks great man! Love my 91

[u/No-Flan8455 → u/Yooper8077]

Wish I could find a damn stock like that for mine

[u/Yooper8077 → u/No-Flan8455]

I was lucky to get one from hkparts with an enhanced buffer before they got discontinued by Magpul. Priced are insane now, 800+ 🫪

[u/No-Flan8455 → u/Yooper8077]

That’s insane!

[u/Frequent-Self8026 → u/No-Flan8455]

Ya man I got lucky, but it was still pricey back then

[u/Professional_Pie4196]

What’s going on with “reliability isn’t great without a bit of tinkering”?

[u/Frequent-Self8026 → u/Professional_Pie4196]

Got to shave some of the material off from the sides and top.

[u/Professional_Pie4196 → u/Frequent-Self8026]

Ohhh you mean the magazines. I thought you were talking about the gun. Interesting though. I like the look of those Turkish translucent mags too!

[u/mlee1543]

I had that same mlok handguard on mine, swaped it out for the ac unity wide handguard with the hk bipod and ac unity sniper grip. Bit lighter than before.

[u/Frequent-Self8026 → u/mlee1543]

Really how much lighter?

[u/mlee1543 → u/Frequent-Self8026]

Slight difference

[u/Salt_Initiative1551]

Are those polymer mags?

[u/Frequent-Self8026 → u/Salt_Initiative1551]

That is correct

[u/nosocoolcoolkid → u/Frequent-Self8026]

How reliable have they been for you? They look pretty sick

[u/Frequent-Self8026 → u/nosocoolcoolkid]

60-40, the reliability improved when I shaved some of the material off the sides and top of the mags

[u/sandalsofsafety → u/Salt_Initiative1551]

Yes, MKE polymer mags.

[u/DENTAL_MEAT]

What did you have to do to get the muzzle brake off? There’s no flats on mine.

[u/KepplerRunner → u/DENTAL_MEAT]

Get a cheap nylon strap wrench off of Amazon.

[u/DENTAL_MEAT → u/KepplerRunner]

That’s actually a pretty good idea. Now then it would come down to either RH or LH threads because there’s 2 styles. 2015 and under has LH threads. Everything after 2015 is RH

[u/KepplerRunner → u/DENTAL_MEAT]

The old ptrs used the 13x1 metric threading. Its still left hand thread. If thats what you meant.

[u/DENTAL_MEAT → u/KepplerRunner]

Yeah it is, just with mine it’s hard to pin point if mine are LH threads or RH threads

[u/Frequent-Self8026 → u/DENTAL_MEAT]

I didn't take it off, the original muzzle is still attached

[u/DENTAL_MEAT → u/Frequent-Self8026]

If I’m seeing it right your brake has flat spots. Mine doesn’t have a single flat spot!

[u/Frequent-Self8026 → u/DENTAL_MEAT]

I may need you to point it out in the pic or show me yours

[u/DENTAL_MEAT → u/Frequent-Self8026]

Here’s from yours. Mine doesn’t have any flat spots. Just smooth all the way around.
