The dealer who sold me my silencer, an AAC m4-1000 also sold me 4 51t blackout mounts, which apparently ruin the springs on my can. Desperately trying to find some 18-t mounts for a reasonable price. Willing to trade out my 51t mounts. I also have various parts and what not if you want to trade for them.
