    Color has a green tint to it.

    Posted by Matthew on 23rd Sep 2025

    The handguard is nice quality seems good for the price. My biggest gripe is that it has a green tint to the "black" color. I bought all new stuff to get rid of the green parts on my rifle because I dont like that color and this comes with it slightly. But other than that seems good definitely for the price. Does hold slightly off to the side a bit but whatever. To anyone who is running a suppressor I would say order with caution. Mine fits but just by literally .020 according to my feeler gage. Granted I do like the seamless look with it so close. But as far as the fitment, if you have a CA-3 it "will not" fit unless you are alright with scratching your bayonet lug. You will have to use some force to flex the handguard over it plus get a little scratches. To me worth it but just a heads up. Also I guess anyone else who has a rifle with the bayonet lug not just the CA-3s. Overall I like it just I am mad about the green tint on the "black"

    Will not fit a Century Arms CA-3

    Doesn't fit a CA-3, not without cutting off the wielded sling mount under the front sight, I was very let down by this, I may be returning it

    This is a huge upgrade from the default polymer handguards that the PTR-91 comes with. It helps manage heat far better and best of all you can mount accessories like a foregrip, bipod, light, etc. I had a slight bit of trouble getting the screw in to hold it in place but just had to put more pressure towards the rear of the rifle and it went in easily. I would recommend this handguard to anyone with a PTR-91 with an 18' barrel.

    It is lightweight and feels durable. There's a slight gap between the hanguard and receiver but compared the stock furniture I had to deal with beforehand it is an upgrade for sure.

    Put this on my C308. Just make sure to tighten the screw all the way or it will come loose. Other than that I really love it.

    This is worth every penny. It makes the G3 clone look amazing and it makes holding the rifle with a C clamp grip so much easier. I used mine for a PTR91 full length rifle.

    I have a c308 so not an exactly a G3 or a PTR. This handguard needed a little help to fit on my c308. I'm not sure if the handguard overall was to short or if where it fits into the receiver that's deeper on the C308, either way it was loose because it was to short to fit snug and tight. I fixed this by putting a washer between the barrel and handguard that the bold fit through. So it will work for a C308 you just need to be creative to get a tight fit that won't go anywhere. I can't speak to the fit on an actual G3 or PTR
