Melonite coated barrel, FSB, and gas tube. Nickel Boron barrel extension. The thing is built for corrosive ammo! 
*I know you said pick between the two you listed, but I felt my input on the Spikes might be usefull. |

*I know you said pick between the two you listed, but I felt my input on the Spikes might be usefull. +1 Spike's midlength upper is the heat. Mine crossed over 1k rounds today without yet being cleaned. Nothing has rusted or pitted. This thing is extremely corrosion resistant. I've had more than a few failures to feed with Cproducts mags (junk) but all my ASC mags, which look the same, have been reliable. The upper itself has run flawlessly as well. |

Is the spikes still available, I heard aim bought them all and they are sold out You can pre order them from AIM. Spikes is making more, the barrels are/were being coated a few weeks ago. Link to thread |

It's dirty as hell but I see no rust anywhere. Probably gonna go through another 800 rounds before I clean it. |
