View Full Version : Throwing out an idea- PTR 91 grip...

Well, I just bought a PTR 91 that I was not expecting to buy. (you do understand, yes? :o ). Since I have small hands, putting on a mechanics glove and sticking my smallish female fingers in the ejection port to reload seems easy enough but... While I wait YET AGAIN FOR THE BILLIONTH TIME :mad: to pick up my new money pit LOL (need dies, brass bullets...) I've been thinking about making a non-pistol grip. Now since the grip fits on a frame that is the full length of the grip, it would have to be a straight down grip like the original but with a 'wing' sticking out the back to prevent my getting my thumb around the back. The rifle has a standard stock, and bull barrel without a FS so the only thing holding me back is that darn grip. Does anybody have a suggestion as to material, something I can possibly 'build up' into a shape, then cut/sand to fit over the frame the original grip attaches to? Does anybody see a legal issue with a grip that sweeps down at the same angle as the original, but with no ability to get the thumb around the back?

Just thinking out loud here...

A few members here have just cut off the grip portion of the LFCG (Lower fire control group) and leave the part that pins on to the receiver and or butt stock.


And Yes I do understand the need to buy something when it becomes available I have been doing this like 3 or 4 times since Christmas.

A HK41 a NIB FN 50.63, well actually 2 FN 50.63's . but thats part of the fun.

I was thinking of making something more like the Kydex grip that someone here did for an AR (with a knife built in), and building it over/around the existing grip, basically giving it a 'fin' like the monsterman so you can't do the pistol style grasp. Or using something like Kato Polyclay to mold a grip that will fit over the existing grip base and fill the back in. I'm leaning to the polyclay, never used the stuff and will be researching in this direction. I do not want to go 'gripless', but rather non pistol grip. When I get my ptr, I will be able to visualize more. Interesting that I have not seen anybody go down this road with the PTR here, but instead lopped of the grip.

You could purchase a metal trigger grip frame from an original HK91 or HK94 and take the plastic grip off and then cut the metal extension to make a modified grip.

Check the surplus sites as they can be found for cheap sometimes.

Go to Tap Plastics and get a piece of plastic out of their parts bin. Cut it to fit between the rear of the grip and the bottom of the stock.

Install and presto! Instant non-pistol grip. Cheaper than destryong part of a trigger housing, and the plastic grip is replaceable.

I have to say it is a personal choice. However.....
Do you really think you have control of your .308 rifle without a handgrip ? Is it really worth compromising safety ?

I've put a lot of thought into a non-pistol ptr grip. I'm not crazy about cutting off the plastic or metal grip as some have done. Some Kydex molded around a plastic "navy" style lower would probably be prety safe, as it would be very strong and hard to remove. My worry about gluing on a piece of plastic or modifying the plastic grip that goes on a metal lower is that it could be broken off or removed "by accident" in an evidence locker and then there is a metal "grip" sticking down.

What I decided to do is get some metal lowers and weld a fin on the back of the grip portion. Then I'll cut the back of the plastic over-grip so it will fit around the fin. That way I don't have to destroy a "navy" lower and there is no way to break off the fin. I think it will look good too.

Remember, if you go "gripless" you need to take off the flash hider. One of the vendors sells a nice muzzle break that screws right on the PTR. Also no folding or collapsing stocks.

If you are reloading to save money that is good, but the PTR will destroy your brass so you will only be able to use them once. You might get some SA surplus while there is still some left.

There was a previous thread on Calguns of someone showing exactly that idea. I can't find the pic now, but it had an extreme angle backward of the re-welded grip frame, more parallel to the receiver.

Also, this was posted here on Calguns by hiyabrad:

I think my kydex style grip will work great for this application.

http://www.calguns.net/calgunforum/showthread.php?t=39534

Make sure to put in a thumstud like I did at the bottom of the thread, it makes the rifle almost as easy to control as an evil pistol grip. I've since learned that Delrin really shouldn't be glued; supposedly, nothing will stick. I havenít had a problem yet with my setup, but if I were to do it again, Iíd use polycarbonate rod instead.

This is a fairly easy mod that will only take a couple of evenings of work and doesnít need any really fancy tools.

I did exactly what you are describing on my V93 ~ will post pics when I get home :)

I would not recommend removing the grip completely on a 308 ~

right side pocketed for "monkey paw"

All modes took about 2hrs from scetch to cut out to heat gun and pop rivets. Used the .6mil thickness tactical kydex. Installed "freedom screw" on left side of PG to make sure "fin" could not be spun around by force. I will remove this screw and the fin when I am free :)

That is along the idea of what I was thinking, but I was going to mold/fit a complete grip. I see no reason to cut up perfectly good gunparts to end up with no grip. And I want a grip, just not a pistol grip :D .

First step, is to get the rifle from it's place of repose... (thanks KALI) the Saturday after next. Then I will take a good hard look, and either fab a bullet button or grip... Until I come up with something, it will stay fixed mag. This is my last gun purchase for a long time unless legislation forces action and I want to set it up right. Not hack it up. Good job Tiger, that rifle looks sweet.

Well, because the lower detaches in seconds, and the steelies can be had for anywhere from $60 to $99 with trigger group, I would get one of those, and modify it while leaving your Navy plastic lower (or nicer JLD S/A steel lower) intact for a quick swap when in "free"range.

The clip and pin project is nowhere near as difficult as one may presume, and the steel lowers are all over the internet, even some that can be had already clipped and pinned if you have no wish to modify it yourself.

I wouldn not cut OFF the pistol grip to the trigger guard either, though the one picture showed as such. What I did was knock out a short section of the skeleton portion of the back strap, sweep it back, and sculpted a wood grip ( I do Elizabethean/Victorian style wood carving) similar to the MM grip, to slip over the swept back portion. I'll do pics when I get the chance.

I agree - one should not go wholly gripless on the PTR-91. But to go fixed mag is an exercise in frustration. These just don't crack open very easily like an AR - it will get old fast.

Hey tiger, where'd you get your rifle? Thats pretty nice it may just convince me to get one....

T ~ that was my thinking, clipped & pinned poly's are $150 and I just couldn't see spending more than 10% the cost of the rifle for the privelage of living in our state :)
