Things are looking up for my DE
 

So, I just read some stuff on the Magnum Research page about parts wearing over time. The Mark 7 has a recommended change on recoil springs every 5000 rounds. Now, it also states that some of the parts with wear from time even without shooting. It just so happens, the gun is 19 years old hahaha.

since you were using good factory ammo clean port its gotta be the springs. good luck. let us know wht happens

Will do, I can get springs for 50 bucks too, and it comes with ejector replacements too
