Are you thinking what I am thinking? Ok, maybe the title has given it away. But the high FPS and the top Picatinny weaver rail of this futuristic WinGun M87 (depicted in the photo above) just begs to be built into a science fiction airsoft sniper rifle. This article depicts some concepts for this idea and my path to this pistol conversion. Links to the parts presented in this articles are in the "Related Links" section below.
The WinGun M87 is an airsoft pistol that is a replica of the Beretta 87 Target firearm. It is powered by CO2 gas cartridges and shoots too hot--approximately 450 FPS--for many airsoft field. But its velocity does fall into the sniper range. It has a full top Picatinny weaver rail that helps customize this pistol easily.
See our "WinGun M87 Sport 301L Review" article.
The WinGun M87 is the base of this futuristic airsoft sniper rifle, because it has all of the mechanism to propel airsoft BB's.
The DBoys M4 Modular Railed Handguard (depicted in the photo at the top of this article) is an attachment to the M4 upper receiver to provide a railed handguard. It has a futuristic look and will provide the front-end aesthetics of this science fiction sniper rifle. The WinGun M87 has a top Picatinna weaver rail, so theoretically, the DBoys M4 Modular Railed Handguard can directly attach to the WinGun M87 without modification.
But that was not the case, because the rail on the WinGun M87 didn't actually run all the way to the edge. So the only way I was able to connect the two was to use Airsoft3D Custom Height Picatinny Risers (see photo below).
After using the Airsoft3D 12mm risers, I was able to attach the DBoys M4 Modular Railed Handguard to the top of the WinGun M87 pistol (see photo below). Turned out that the 12mm risers centered barrel on the handguard perfectly.
I had already painted the handguard a tan camouflage. And I had removed the metal rails. They were extremely heavy. I think it's time to get some of Airsoft3D's Light Weight Picatinny Rails for this thing.
All sniper rifles have a large shoulder stock to provide stability support. It would also give the gun a menacing look. A stock from VSS Vintorez, SVD, or Echo1 MTC-3 would probably ideal.
There is no direct shoulder stock attachment for the WinGun M87. Therefore, you'll need to do a bit of modification. A cheap low-power electronic gun (LPEG) or bone yard sniper gun could provide the stock.
The shoulder stock photo, at the top of this article, depicts the Crosman 1377 Custom Shoulder Stock. It's not as menacing as the shoulder stocks from guns just mentioned, but it's made for pistols and may be easier to modify for this purpose.
