by Luke C.

Welcome to TFB Weekly Web Deals 35. The holiday season always brings in a lot of new guns and new gun owners. Whether you’re picking up your first AR, or your 15th AR, there’s always room for improvement from the base product unless you’re already paying top dollar for one. In light of that fact, today we’ll be focusing on things that you can buy to upgrade a budget AR-15 beyond what already comes on it. If you’re looking for a couple of great examples of what TFBTV staff does with this concept, you can check out one of our more recent videos where TFBTV’s James Reeves and Hop are in the midst of a build-off where they’re working with a budget of just $1,250. If you like the idea of taking a basic AR-15 rifle and upgrading it yourself or you just happen to find yourself with an extra rifle this holiday season, these deals on firearms parts are sure to help you make those upgrades and save you a few bucks in the process. We’ll also be throwing in a handful of other neat deals I’ve found across the web from this last week. Happy building everyone!
