If you’ve finished off a stripped lower recently you’re probably pretty familiar with the fact that the cost can really start adding up. Palmetto State Armory has a sale going on right now for their Magpul STR Lower Build Kit. It usually retails for $220 but they have it on sale right now for just $150. If you’ve got a lower sitting around waiting to be finished this is a great way to do it but this deal ends tomorrow at 12 noon est. Purchase now at PalmettoStateArmory.com.
