Name says it all, this glitch allows your bullet speed to improve to that of a lancers. However, this has a downfall, it makes it so the gun's bullets ony do the damage of a bullet from the lancer. However, it still looks cool so it will be taught...
1) Do the first part of Remote Chainsaw until your shooting blanks, but do the glitch right onfornt of an enemy
2) Change to the gun that you want automatic, you'll see you start chainsaw animation but you'll end with the gun you want automatic
3) Change Back to your Lancer and You'll have Automatic Gun
