WTT- 6921 upper for 6920 upper **San Diego**

[FCOD]

I have a 6921 upper with a pinned/ welded Vortex flash hider that I'd like to trade for a 6920 upper. I liked the 14.5" for my M4gery, but would now rather have the 16" barrel. This comes with a Rifle Gear BCG and the upper has about 400 rounds through it. Got it from a friend who was the original owner.

This is pinned/ welded so not an NFA item. Looking for something local only. I am located in north county San Diego.

Thanks!
