Need some help scoping a FAMAS

[UKAirsoftNick]

Hey all (this is my first post here so be gentle :P) also I've used search and couldn't find anything like this elsewhere but apologies none the less if its already been explained or is just a stupid question.

I need help scoping my FAMAS, the problem with it is that the FAMAS rail attaches to the carry handle, which is a good 10cm above the barrel. This means that aiming can be awkward (see diagram a. below). I was wondering, on a typical scope is there a calibration device to adapt for this? Because I dont want to buy a rail and scope to find there is no way of compensating for the angle of the scope and barrel.

The only sight i've ever used is a Trilux SUSAT sight on a real steal L85 A1, and it did have a calibration and zeroing function - but does a normal airsoft scope? In a way it basically needs the rear of the scope to have a varibale upwards tilt (to compensate for distance, that was how the SUSAT sight worked). Alternativley other scopes i've heard of have refractive lens's that can compensate for the fact the scope and barrel are quite far apart.

Ok, so heres a picture to help illustrate what im getting at.



Picture b.) is what im trying to achieve - a sort of tilited scope, or scope that has variable refraction inside it. Do these exist, are all scopes capable of this, and do you guys (and gals) know which ones do and don't have this ability? Ideally i want a scope able to quicly adjust for distance, most the time I use the night time battle (iron) sight to aim in airsoft but a scope would be damn useful at distance.

Thanks! (again sorry if its a stupid question!)

i threw on a g&p m16 scope on my famas, it worked fine. but i mostly used mine to identify targets not as closed sights, either way it worked for both purposes. oh btw the pics are sweet addition. i dont think youd get flamed if you but this kind of detail in all you "noob" questions.

Great, but is your sight actually zeroed with your rifle? I know thats kinda contradiction in terms because its pretty impossible to get a BB pellet to hit the same spot even 6 out of 10 times at as little as 5 meters but i mean a rough zeroing?

Or do you just use your scope as a sort of rifle mounted monocular?

a tilted scope is pointless as your hit zone would only be at a VERY specific distance. you would need a range finder to use it properly, and you would have to use extreme compensation for anything not at that perfect distance.

All our guns have elevated optics, its not a problem.


FYI, airsoft guns are nowhere near accurate enough to worry about the sight offset.

well it was zero'd as best i could, the groupings were fairly decent and were visable in the scope at about 50-70ft. but ya i mostly used it as a monocular. where i was looking was were the bbs were going, just not on the crosshairs.

Yea I realise that, I was in the Army so zeroing by judgement rather than by sights is quite second nature (as is my urge to aim for the torso and not the head). like I said in my previous post i agree that its hard to get even 6 out of 10 shots in a grouping with a BB gun due to the descrepant nature of their fire.

I guess a trully effective BB scope would need a way of rapidly adjusting 'the perfect zeroing point' for distance. When I was in the Army the L85 A1 SUSAT sight adapted by having two adjustable points at the front and back of the sight, so at say long range the front would be only slightly lower than the back, at close ranges the back would be elevated and the front depressed considerably more. Although When i say close ranges i mean 100meters, so i get what you mean by it being pointless to have it excessivley zeroed.

In the army we were taught to judge distances in terms of football fields, its quite an aquired art to be able to accurateley look at a field and judge how wide it is to set your sights. We had none of that US army "ill just get my rangefinder" nonesense lol.

Ahh that sounds quite good, thats pretty much what i'm going for. I'd be kidding myself if i expected my shots to fall on the cross hairs precisley, but i'd like them to be mostly visible through the scope at roughly the zero point.

I think what I'll probably do is just spend a few days in the back garden practising firing at different ranges until i learn where to aim at what distance in relation to the cross hairs rather than try to zero the cross hairs for each possible distance I may encounter. (which would be impossible).

E.g. at say roughly 15m aim 3 divisons up of the cross hair zero point approximateley to hit a person sized target if aiming at the torso. Although as we know airsoft sniping is never one shot one kill.

Id probably just do it like that, and use them as a sort of fixed monocular that could also double as a scope to some extent.

Cheers to that... I'm afraid that I'll save you the trouble of PM'ing me, and tell you personally that I can't help, though.
I haven't fitted a scope yet, and when I do, it's going to be on a different handle- I'm replacing it with a G36 one.
I've noticed that problem too, that the rounds actually end up furthur down in the target then where I aimed, because of the insanely high mount. Anyways, I'm sure that many sights can be adjusted for declination, I know this for a fact- yet for brand names and individual models, I'm afraid I couldn't help you.
However, to tilt the scope- on the rail, I believe that by dremelling off part of the bottom, and tilting the rail downwards, you should be able to tilt your scope/sight downwards, if that's what you wanted. The rail is only bolted onto a hole on the left side, and simply sits there- if you take off part of the bottom, it shouldn't be too hard.
Cheers, good luck.

Thats ok man, by the way - I believe it was you who made the 'stop your FAMAS squeaking' upgrade guide? That was the first upgrade i ever did to an airosft AEG and it worked a treat. I modified it in places and had a longer screw attached to the handgrip to give some extra strength, but thanks, it was excellent!

I also have a plan to add a small container into the handgrip of my FAMAS SV - i have a theory that Tokyo Mauri intented on the handgrip hatch actually opening and containing stuff, but found the weight of the things people put in there opened the hatch on the bottom and the stuff would fall out, so they glued the hatch shut (badly) but im working on a clip to fasten it in place so things wont fall out. If you want details i'd be happy to send you them for your upgrade when i've finalised how im gonna do it.

People say the FAMAS can't be upgraded - they're just ignorant. It has enormous potential because theres so much space inside it to add things. One idea i had was to put a battery above the barrel in the foregrip, (above the main 8.4v battery) and run a wire up through the cocking handle hole and wire it into the sight incase i get a powered sight (e.g. night vision)

Yup, that was me
Anyways, I'd be glad to see what you're doing- I keep odds-and-ends in the FA-MAS, as well, inside the pistol-grip I keep a small baggie of .25s. The hatch doesn't open, too, it's fairly tight and the BBs are really light, as well- you can open the hatch, and they won't fall out, because they're kept together by the side.
Yeah, that's true- there's a multitude of FA-MAS upgrades, you just need to know what to do (I don't know very well, really, only last week I was saved from making my gears self-destruct). The night-sights idea is amazing, to say the least- I'd like to see how this turns out. It'd be hard to do, though.

I take it you use 250 microgram (.25s) pellets for your FAMAS? Hows that working out for you? I've been using 200's (.20s) and find them to have exceptional range for the FAMAS FPS but rather lacking in accuracy. Sadly i have 10,000 of them but when they run out shortly i suspect i will try some .25s instead, have you ever used anything bigger than that? Im also interested to see how 230s perform as they seem to be all the rage at the moment.

Wouldn't that be milligram? Or 250000 microgram?

I find they work amazingly well, that's probably why the FA-MAS came with a bunch.
From 15 metres, I can put all the shots through the same hole. There's very little deviation, at all.
I haven't tried .23s, yet, I'm afraid, but I have some .2s coming in by Friday- I should be able to get you some stats with that.

yea wasn't paying attention to what i was writting, it would be 250 milligrams as a milligram is 10^-3 grams. sorry.
