i order a spikes lower about two weeks ago. the company sent me out a surplus arms one by mistake. they called me once they caught it and offered to stop the package and send me out the spikes or give me a great deal on the surplus arms lower. since i was considering ordering two spikes lowers i said ill take the surplus arms but can you please send the spikes also. both me and my ffl were very impress with the quality of the surplus arms lower. the bulls eye logo and the pictograms for fire control look pretty neat. now i need to decided which to use for my sbr build.
