Trade my 6 shell tacstar side saddle for m4 trigger axle bushing, retaining ring, spacer and retaining spring.

[Jerryc]

My m4 came with a tacstar side saddle and I’m looking for someone to trade for the factory trigger axle pin, retaining ring, spacer and spring.

You're going to be hard pressed to find someone willing to make that trade if being honest.

What I would do is I would purchase the items you need from either Brownells or Numrich.
