Thanks for the compliment!
Today, I decided to finally draw guns from scratch, well one of them still use Colosseum's part and they're colours are admittedly gathered from other drawings. So, if there's a rule about me having to credit others because I use their colours then I will do so.
At any rate, first and foremost is the Stoner 63 Assault Rifle. Also known as the XM22 in the US Armed Forces, it was rejected when it was considered to be used as the replacement for the M16A1/AR-15 rifles.
Next is the British Thorpe's EM1 and the Janson's EM2. Both are chambered with the .280 British and use a bullpup configuration. The EM1 is rejected primarily due to being too complicated for battlefield use.
Then is the Janson's rifle, the EM2 or the Number 9 Rifle. Called the best Cold War rifle that never was by Ian McCollum of Forgotten Weapons fame, the EM2 was adopted and fairly quickly unadopted due to politics.
Finally, a fairly old drawing of mine, the AA-12 full-automatic shotgun. It doesn't have any iron sight and only have a picatinny rail for optic attachments.
As always, do point out any mistakes on my drawing. As they are pretty much the first few drawings I have done from scratch, I apologise for any mistakes!
