Good parts for the lower, Scott. You shouldn't run into any problems. And upgrading the trigger is easy whenever you want to do it.
A shame these horrible shootings continue to happen. And disgusting that there are so many people who are overjoyed that it happens so they can push their gun control agenda. We saw a lot of them on TV today and they already are pointing fingers at law abiding gun owners like us.
The biggest issue with assembling an AR isn't so much getting the parts together right - it's getting the right parts together.
