Join me in overthinking this AR BCG purchase

[John Browning]

Well, for a .300 AAC pistol I'm down to this

and this

There is no difference in cost. The AIM is 9310 steel that is shot-peened/MPI inspected. The PSA is 158 Carpenter steel that is shot-peened. They cost the same and look the same and work the same and I am way overthinking this, so I need you to tell me what to do.

Go with the place that has cheaper shipping.

Go with the place that has cheaper shipping.

^ and no Cali sales tax.

I would go with AIM, free shipping on this BCG. I do have the PSA one and it looks great. Just had to stake the gas key a little better but then again it is my back up BCG and not one that is currently in use.

Unless you are running and gunning on a daily basis in Afghanistan, both will work just fine. You are over thinking it. If you doubt the quality get one here. http://midwestpx.com/product_info.ph...roducts_id=626
