What other FX Impact upper picatinny rail options?

[bigHUN]

I have this MK2 I dedicate it for BR shooting, and trying to figure a way to mount the scope further back towards the stock, so I can completely sit from end of a bench.
Recently we got some options on the market that would replace the MK2 upper picatinny scope rail (D1) plus the upper guiding/connecting plate (B14) as for example the AirMarksman backbone rail but there are some others as well.
Just looking at the online pictures I am not sure yet how I would like lowering the scope height. Currently the Falcon X50 is set at 82.8mm clamped with eaglevision adjustable rings.
Currently this is my BR setup and I want to move the scope backwards, and eventually I can redesign the entire stock - remove the PL spacer and the Gehmann not to touch the body.

I don’t fully understand what you’re trying to accomplish. So if I sound crazy with this statement. It well deserved.

Could you mount a universal pic rail to the top of the back bone. Of course you have to remove the cheek riser and maybe the factory pic riser that’s on it now.

 

[bigHUN]

Yes, that could be done, but the amount of effort then just buy a full length upper "guiding plate". So far every modification I have done on this MK2 never on original parts but always bought spares and did the fabrications on those.
I just don't know how far back I can get the new picatinny slots.

Atilla, I will measure and give you the dimensions from the rear of the Airmarksman’s plate forward to the first picatinny ok

 

[Bigragu]

Ok- here we go-

From
The very back of the AM rail to the picatinny that would catch an entire scope ring base so the rear of your scope ring isn’t overhanging out past the scope rail-

And from the underside of the AM rail where it sits on top of the cocking block and rear block, to center of scope, using an arken cantilever mount-

 

[Bigragu]

That measurement in the first two pics is not of a scope mount, but of a monstrum side picatinny attachment which is the same width as say a typical fx no limit mount. It catches one picatinny slot.

I have to find out what the height of the arken mount is, to give you and idea of your scope height if you went with the AM rail.

Like many others that installed the AM rail, they had to raise their cheek weld up. I already have a saber tactical adjustable cheek riser so it wasn’t a big deal

I really like this mount. Very strong, and a 20 MOA built in for under a $100. I used to use Athlon but Athlon cantilever mount with 20 MOA in 30 or 34mm is over a $100

 

[Bigragu]

If you compare my pics to the factory scope rail, the AM rail starts its scope rail on top of the power plenum by a third, while the factory scope rail is above the rear of the power wheel dial, then starts the actual picatinny mounts an inch forward from that slant.

I think the AM rail will fill your needs, and you will be amazed at how much more robust the gun will feel.

Thank you Sir, with the measuring tape I can see the scope can be moved roughly about 2" towards the stock, vs the original FX rail.
That is a significant change, the scope height is a secondary target only.
I will need to check on the tabletop if my adjustable rings have enough extension to clear the front bell.

If you need anymore dimensions or close up pics, just send a pm ok, mr Bighun

Forgot one thing. When you flip up the ST butstock to vertical position, looking from the end (not from cheekweld), can you aim through a scope? Is there enough clearance for clear eye box looking above the stock top edge?

I cannot find any dimensions, what is a total length for the Backbone Rail from AirMarksman, Long - Medium - Short?
Also what is a "thickness" from bottom face of the rail to top face of picatinny.

Could you use a cantilever mount backwards?
Athlon makes a 0 moa mount thats well built and doesn’t break the bank. Most likely will be lower though.

I will send a sketch with dimensions of the rail

I will send a sketch with dimensions of the rail

For the case that I would chose the long rail. I called my AGS dealer but "my" guy is away for a week.

 

[bigHUN]

I starting taking things apart again to do some measurments.
If I want to aim like a real BR shooter from behind the stock (my X50 has a long eye relief) in order to have a full eye box, I need to move the scope to this location.

That mounting option doesn't exist for FX Impact, so I will need to design it, a combination of new upper plate and a adjustable picatinny block raised to 24mm.

 

[Bigragu]

Sent you the dimensions via pm today

 

[bigHUN]

I got the 25 cm =10" rail today. So the new guide plate will look like this, but a bit thicker because the screw thread depth in middle of the plate.

I would think the Airmarksman backbone rail would do the trick, but it is expenive.
