What have you made?

I have been slightly obsessed with the Crye MR-C after the Ghost Recon Advanced Warfighter game 'back in the day'. The gun itself was never more than a mockup - but I've always wanted to build one, even sketching out the idea in photoshop ~15 Years ago:

I have been learning to use Plasticity 3D recently and I love it - so as a learning exercise I decided to try and build a 3D model of the MR-C based off the very few reference images of the real thing (there are loads of references of the in-game model but they are not particularly accurate)

Mockup Pics:

Still got a fair bit to do - I'm not 100% happy with the grip shape and the mockups didn't have triggers, so I'll have to guess on that. I will also model the Grenade Launcher at some point too.

Not sure if I can build it into any kind of functional airsoft gun - it would make a pretty cool wall-hanger.

Pretty much finished the MR-C Model - I luckily came across a couple of official Crye renders of the gun (via the Internet Archive from Crye's own website ) which made me realise that the proportions were wrong.

So I basically rebuilt the whole thing again, but I had a lot fun doing so.

Seems like the real thing was a very small gun - just over 700mm, which is fixed-stock MP5 territory.

@mightyjebus Don't suppose you have a V2 or V3 GB model that I can use to check if it's viable to build the gun? I did model one myself last year - but lost the file.

it looks like the V2 will be too tall so you have to get creative :)

You are right. The GB will fit - but a motor will not. Oh well.

If I had money I would consider an HPA-specific build negating the need for the GB shell/motor, but that's out of my price range. Finding a long enough length of Picatinny extrusion for the upper rail in the UK is a ballache as well (the front end would be a 38mm Aluminium box extrusion with metal rail segments bolted on) so I will shelve the idea.

Had fun putting the model together though.

 
So this sort of twattery occurs when you have too much time on your hands... turning a pallet into a backstop for my garden test shoots

The cunning plan was to cut strips of an old yoga mat and suspend them from a bar to absorb the hits and ensure there aren't BB's bouncing noisily off the fence (which might annoy the neighbours).
Also would stop the BB's bouncing back on to the lawn (which might annoy m'wife).   You can see previous evidence of my misdemeanors in the photos ;)

Unfortunately it wasn't all that cunning... the yoga mat wasn't really big enough to provide enough strips to overlap well, so I added the camo netting doubled over, front and back (which was originally intended just for the front, just for effect).  That really didn't do much except tangle up the strips and probably get in the way of them hanging straight.  

So BB's are going all the way through to the last layer of defence, some old under-flooring insulation (a very frangible fibreboard).   Eventually they'll get through that too, given how the concentrated bursts are grouping so nicely.

Any good ideas on what else I can do (cheaply!) to improve this?   I could get another cheapo mat and just add extra strips, if you guys think the original plan was good enough?

I think I saw a yoga mat in Asda or Tesco for a tenner a while ago, so I think that's got to be worth a shot - I should be able to ensure a good coverage, and I'll probably cut much wider strips (3-4" ?) to make sure they stay in place better

I would think you'd want the strips as wide as possible to absorb the impact with them moving as little as possible, especially if you're firing bursts

I'm trying to imagine the physics of it all ... it's hard to think that even a wide strip wouldn't get kicked out of the way by 5-10 BB's hitting it in a decent burst.  Do I hold it place with elastic bands at the bottom?  Or weight them at the bottom of each strip?   If they resist too much the BB's will punch through them.    Arrgghh!

Gavin, I can see the sense in an NBC suit, presumably that's a rip-stop material?  I don't have any to hand that I could cannibalize though...

Maybe I'll just buy a couple of cheap car mats as the fail-safe backstop.     (You know what's really annoying is that I just replaced my shed roof.   It's covered in rubber membrane.  With quite a bit spare all around... all securely fixed in place now!)

Edit:  Astroturf?  It's weatherproof, pretty indestructible, green... and there's a shop near me that might have off-cuts...

I was thinking leave the mats hanging loose at the bottom to allow some movement, but the car mats sounds like a better idea. They'll take far more abuse before failing

 
What about some rubber sheet, it could be purchased as a sheet and then hung by the top edge only. Or butchers curtain in two layers, the movement should take some of the bounce out of the bb and allow to to drop, with the second layer there to stop bursts.

Old carpet works well as a backstop. The Airgun club I'm a member of uses it for their target stands. My local (independant) carpet shop has skips full of the old carpets removed from customer houses. Ask nicely and you have enough for a dozen backstops for free.

 
To be fair, ALMOST anything will do, even putting a couple of small crocodile clips in a box setup & hanging a newspaper or light magazine up, strong enough to stop & soak the power, but light enough to flex & not allow ricochets. 

If I was planning to build a catcher/target box, I would consider using commercial carpet tiles, the kind usually found in office environments, very hard wearing & quite stiff but with just enough flex that bb's wouldn't break if they hit edges etc, which is an issue with most commercial box catchers. 

EDIT : I should add these aren't cheap, far from it so prob not best to Google them ?lol, but if you or a relative/friend work in an office environment, a friendly chat with the resident building services person should blag half a dozen, most buildings have a basement lockup with stacks of these secondhand for reusing in renovations or partition changes.

I made a trip out to the wilds this morning and popped in at Halfords, found these...

£6 each, they're not too thick so retain some flexibility.  Each one can be cut in half to make 'larger than A4' stoppers, so I'll arrange them such that they're dangling by paracord and will stop ~95% of my shots. I'll re-arrange the yoga mat strips as the first line of defence (to quieten the impact, hopefully)   The odd flyer can be caught by everything else.  

I wanted something vaguely weatherproof in case the rain blows in on it... but carpet would've been good enough to last for a good long while though, given it's mostly nylon these days.  So that was a good shout.  I could've saved £12!
