M4 SOPMOD airgun replica
« on: October 30, 2009, 02:42:09 PM »
This is my latest airgun replica and its the most detailed gun I have ever made...



-thats a 200mm suppressor on the tip of the barrel, its got an inner barrel with 60 holes in 4 rows and outer barrel with 144 holes in 8 rows and some cotton wool in between. it works extremely well in reducing noise and white smoke coming out the barrel due decompression.



its got a 500mm barrel thats held in place with a 350mm bolt and its just over 1,5 kg. The frame is made out of fir wood and the airtank (3/4) out of green ekoplastik pvc rated at 20 bar for 20°C and 10 bar for 67°C. For filling I use a schrader valve thats hidden in the stock... all you can see of it is a small rubber cap.

It has a removable magazine that holds 2 rounds (2 nail darts on the pic), in the front there are 3 picatinny rails and 1 long on the top. The sights are adjustable for windage(rear) and elevation(front) but the rear sight doesnt grip the rail very well so I think I'll have to redesign it and make another one... The triggersystem opens the 1/2 valve via spring and redirecting screws.

The trigger and "spring release module" is self resetting... all I did was put a pivot point inside the release thing... put a tiny wooden dowel in so it can move up n down and a small spring from a pen. So when you pull the trigger and release it, it will automatically come back.

I still have to finish the LMT crane stock and even out the recoil buffer tube. In the place of the mag release button I drilled a hole for a switch to control the laser pointer that will ride in the front sight post. I'm thinking about putting a 5mm LED diode in the front sight post to illuminate short range targets at night... I use 2 pairs AAA 1.5V batteries (for the laser & LED) that are hidden inside the pistol grip.

Bullets I use are primarily nail darts and wax/paper slugs.... and white chalk that fits perfectly into the 12mm barrel  ;D it leaves a nice white mark after it impacts and explodes into small pieces
and... thats about it.... and yeah... it took me about 3 months to make that piece of wood and its still not finished hehe

I wonder how much I'd get for it if I were to sell it... but I'm not going to... there was just too much work put into this thing

If you're very intelligent its likely you're arrogant but if you're arrogant you don't necessarily need to be very intelligent.

That is probably the best looking homemade airgun I have ever seen! That's alot of attention to detail and a lot of carving to get it to look like that. If you can, a video of it in action would be awesome.  ;D
