  • Spike's Tactical AR-15 Lower Parts Kit (No Trigger Group)

    Quality parts at a decent price. Didn't need another milspec trigger (several on hand already)so that helped with reducing the overall cost. Storage in the pistol grip would have been a plus

    While mil spec kits are a dime a dozen and usually terribly over priced. Often they do not all fit as they should. Milspec is different everywhere so if it’s china made its not likely to our military specifications. Even made in USA sometimes just means we’ll charge our own people more for less quality simply based on the made in the USA title. Spikes makes a good quality controlled proper milspec product and that’s where you get what you pay for.
