Hello all!

Bought myself a brand new scar16 the other day. After I got it home, I'm holding it to get a feel for it... and decided that I wasn't really a fan of the picatinny rails on the sides.
"Oh look, each one is only held in my two screws - those should come out nice and easy - then I'll have a nice smooth side to grip instead"

So I grabbed a tool and popped out the first screw (rear) - great!
Then I pulled out the front one - great...
Then I pulled the rail off the side and heard "ping!"

Turns out theres a small piece of metal that extends from the front screw to what looks like a barrel retention screw slightly further front.
I am unable to get that little guy back in place..
Further, the backing piece that the front screw actually threads into has jostled loose and fallen out.

How vital is that little piece of metal? I've done some poking around online and found replacement rails (keymod instead of picatinny) but from as near as I can tell (from pictures) there is no place for that thing on the aftermarket ones.

With regards to the little backplate to thread the screw into... I feel that I'm going to need to remove the bottom side picatinny portion in order to get it back on there. That however is VERY snuggly attached. I suspect that I need a heat gun or something like that to loosen loctite.

Any advice you guys have would be greatly appreciated!

-Mike

The bottom rail is attached to the barrel assembly. Have a look at this video and others on youtube before you remove any more parts. Please don't use a heat gun on it as you might ruin your finish.
That certainly helps!
I wonder if that little piece of metal will be easier to get in if the front screw is loosened - or even maybe removed...

If you remove the side rail entirely you'll see the slot where the retention spring fits, put the screw in first then the spring then you should be G2G!

Tried that - when I attempt to put the rail back in place (with the spring inside the slot) the end of the spring get stuck on top of the ridges of the barrel retention screw. :(

You're putting the retention screw in first yes, then the spring? I have a Branham rail so both of my OEM rails are off, I'm looking at them now and am not quite following how you're having this issue. A photo would be helpful...

OK you guys both rock.

Between the video and the extra dialogue I was able to figure it out and get that little bastard back in!
Now I just need a wrench to cinch the screws down the correct amount and I'm golden.

If either of you are ever in the Raleigh area... I owe you a beer.
I was anticipating having to take this into an armorer to have it looked at.

Glad to be of assistance and you are aware the barrel assembly screws have to be torqued AND torqued in a specific pattern, yes? Oh and I don't drink beer but, if you have some Wild Turkey Rare Breed floatin' around I'll gladly share a shot or two with you! :?

haha - I'm not a beer guy either - I go with rum or whiskey :)
And yes - the video showed the pattern needed starting with the sticker side

It's the little things that seem huge.

But that's what this forum in about. Making the huge issues go away easily.

finally got the screws tightened down correctly - took the scar out to the range today!

first impression: holy **** there is all but zero recoil on this thing! it's a bit unbelievable....
can't wait to get an optic slapped on the top!
