Looking for lower parts for your AR 308 lower? We have them all. From Lower Parts kits (LPK), stock components, trigger kits, 308 conversion kits, the list goes on! And we have some of the most competitive prices you can find for the quality you get and want. Buying parts for your 308 lower can be very confusing, a lot of people think an DPMS LR308 is an AR-10, but they are different. Most of the after market lowers out there such as Aero Precision, Bushmaster, S&W are styled after the DPMS LR-308 platform. You can USUALLY tell by the model number of your lower. If it ends in XX-308 then it DMPS Style .308, but if it ends in a XX-10 its an Armalite AR-10 style. There isnt a huge difference, but you can sell by the slant in the side view of the lower, if it flat then rounds up at the stock like a standard AR15, then its DPMS LR308, but is a slant up to the stock, then its an AR-10 Style. Please note most of what we carry on the website is for the more popular DPMS LR-308 platform and not the AR-10. If it does not say AR-10 on the product then it will not fit the AR-10. Feel free to call us if you have any questions about out .308 lower parts!
