Posted this on Arfcom but everyone ignores everything I post over there so I'm putting it here for more ignoring. 😁

I bought a Chinese quad rail last year to try on a carbine to see if it was as cool as I thought it would be. It's a Monstrum tactical and it cost me $20.

I decided I like a quad rail, so I started looking for an American made quality one.

I decided on the Damage Industries and since I was in no hurry I waited for a sale.

Just hit the Memorial Day sale for free shipping and $80 for the quad rail (normally $129)

The Chinese quad weighs 12.16 ozs and is chonky in the hand.

The DI quad weighs 9.04 ozs and is very slim. Like the quad is narrower than the widest part of the upper receiver.

The DI is much nicer, fits very tight and even has anti rotation lugs that lock into the barrel nut.

Overall I am very happy with the DI quad rail.

DI is on the right.

How is the height? Looking under your scope mount, without a "chinesium" photo I'm guessing you had the scope farther back, or it had a hair of space between the rail and the scope. I guess the $20 china rail isn't going to be used by anyone who needs the top rail to be the same height front to back.

The China rail was the same height when mounted. The LPVO is mounted in the same place as before.

My Robinson XCR is a quad, and I can replace it with a modern M-lok design but it's pricey as it's not just the handguard, it's the whole upper receiver. I may still do it as it's my travel gun being a folder and all.

I went through the rail phase as well. They work well enough but after a bit realized didn't need rails everywhere, but also get that not everyone mounts their acc is the same spot. Would be nice to mount everything up, then mark the rails you don't need and machine off the rest but.... M-lock stuff is nice as it's not there if you don't need it but also that latest whiz-bang thing.
 
Whats the point of the fancy scope with a tactical reticle when the reticle is blocked by the front sight? You dont set variable power scopes to cowitness sights.
 
Build what you like. If you like quad rails, I'm good with your choice. However, I had a LPO (4x ACOG to be specific) on a build that had a fixed A2 sight on 20" barrel. I could see "through" the sight, as you say, but there was still a blurry portion in the objective (where the sight was) that just bugged the crap out of me. You might be better served with a foldable clamp-on FSB such as a YHM (I use many of these). Or not...

Well cowitnessing a variable power scope with iron sites and blocking the reticle is pretty gay. Maybe OPs trying to tell us something? :flipoff2:
 
I was going to type out a post with pictures looking thru the variable optic showing the front sight post and how it appears at different magnification settings so you could see that above 2x the FSP is not an issue and explain how it is not co-witnessed, but I decided not to waste the time. :flipoff2:

Only see the front sight post at 1x power and then it is just like an absolute co-witness red dot.

So is it an absolute cowitness or not cowitnessed? Or just dumb? You should read up on optics that bend light (such as prisms or magnifying lenses) dont work cowitnessing iron sights. But screw physics you do you.
