PTR 91, recommend an optic....pics would be great!

Hey guys, I recently bought a PTR 91 and it came with a PA micro dot (thanks Atlantic!) and I'm thinking I'd like to have a magnified optic for this gun. My eyes are kinda tired so a little help would be great, especially seeing as this gun can easily reach out to some pretty good distances.

I'm thinking a 1x4 or 1x6, something that won't add a ton of weight and is not so long that will interfere with the charging handle, or even a fixed power red dot.

The gun is used for range toy and maybe a hog hunt but primarily hanging out and shooting at probably no more than 400 yards.

Any recommendations? Pics would be great! :)

Hi there. I'm a brand new HK91 clone owner. I just picked-up a new Century Arms C308 at Cabela's last week and put a Vortex Crossfire II 1-4x24 with illuminated reticle on a Burris PEPR mount on it. I took it to the range a few days ago on a very windy day (I was itching to get it sighted-in, and test for reliability). I shot a 2.5", 5-shot group at 100 yards. Considering the wind beating me around and blowing my target stand over several times... I'm VERY happy with that group. I also have an SA M1A that I've had since 2005 and I doubt I could have shot a better group with it considering the wind. So the C308 certainly has me stoked thus far (and was 100% reliable). Now I just need to find a bunch of cheap magazines for it, and I want to put a wide forearm stock on it ala the PTR91. I think I've found a place to buy the latter and will be purchasing that shortly.
Here are some images with vortex optics. The top one is a strike eagle 1-6 bottom is a spitfire 3x. I prefer the spitfire personally.

I'd say that was a very good group! What ammo were you using?

Nice, I'm really liking the look of the Spitfire, I think it fits the PTR better.
A 1-6 (or better) optic is a good match to the range of a .308 rifle. I have the Primary arms 1-6 on mine and have been very pleased with it. This is mounted with the PA generic cantilevered mount and it sits slightly lower on my son's GI R then it does on mine with the clamp on rail.

I bought a bunch of boxes of the PRVI Partizan 147 (or was it 150?) grain stuff from Cabela's on sale. I have a ton of LC Match reloads (and original), but I generally use that for my bolt rifles and occasionally my M1A. I bought the C308 to be my short-medium range thumper... so I don't really plan to shot match ammo in it. Pie plate battle accuracy is all I'm seeking.

Not a variable but this is what I went with ACOG 3.5 green horseshoe with BDC.

Had this on there but moved it to another gun. Now I have a Primary Arms variable 2-6x and it works great out to about 300 meters.

The problem with a fixed power optic is that it is "fixed". So it might be more then you need up close and less then you need at distance.

With the 1-6 I can leave it on x1 to enable quick snap shots and then quickly flip it to x6 for longer ranges if called for.

I agree with both of the quotes and I personally like the old school optics although there are a lot of great new optics as well. I have the Zeiss Diavari 1.5-6x42 "sniper" and 30mm claw mount on my SG1 clone.

I also have a Hensoldt-ZF-Model-Two scope with quick detach mount. Even though these scopes are fixed at 4 power they are very good. They have bullet drop compensation out to 600 meters and are illuminated. If you have one of the newer PTRs with the receiver rail you could mount this with a #63 Arms mount which is raised 3/4" with a see through channel for iron sites and compatible with STANAG mounts.

Yeah, I'm leaning towards the 1x6, I was concerned about it being a little too long and interfering with the charging handle but it looks like you have plenty of room. My eyes could definitely use some help.
That's what the RMR is for. I don't think it's n an optimal choice for bench shooting though.

I didn't like the 1-6 ACSS clarity. It's also more of a 1.25 than a 1x and it's not a serious scope. I use an Eotech til I can get a good 3x Trijicon with an RMR. And the eye relief will suck in the prone or you can't slap the handle. You'll have to decide if you want eye relief or the ability to slap the handle without slapping the scope.

Absent a need to clear rooms an EOTech without a multiplier is really not enough optic for a .308 rifle. Personally I don't think a 3 or 4 power ACOG is either.

I have EOTechs w/multiplier on both my Saiga (7.6sx39) and my wife's SU16CA (5.56). They work well for MOA out to 500yds but un-magnified they run out of steam by 200yds.
The Primary Arms 1-8x ACSS scope is absolutely perfect with the SWFA SSALT mount. You can actually still use your irons with this configuration.

Yep, it really depends on the purpose of the rifle. My k is specifically setup up for one reason: quick target open eye acquisition for close and up to 300 yards. The 3.5 magnification is totally fine up close. It's not setup for rest shooting where I can fool with magnification and get a perfect cheek weld. It's a raise and shoot, I presume that's where you're going with yours. I believe the horse shoe dot is 1MOA too so it works pretty good for longer ranges. There are plenty of uses in between the "clearing rooms" and 500 yard shooting. That's is where the ACOG excels, 3.5x is forgiving on the eye relief too making it a really quick shooter. I know some will think a .308 too much gun for that purpose, but I dissagree with those folks.

I get that's probably not his goal though probably being a rest and hunting shooter. Above looks like a nice setup^^^.
