Today's trend is to build the most lightweight AR-15 possible, without sacrificing performance. (Again note that I added rail panels to it.) This AR pistol I build with a complete BCM upper. One major advantage of the MCMR vs the Aero Precision options covered above is that it has mounting slots at more angles.ĭespite any complaints I mentioned above, this handguard is actually a part of my favorite AR-15. This table shows the lengths and weights of BCM's M-LOK handguards, which can all be found here:Īgain these weights are for the handguards only and do not include mounting hardware. However, this is a general 'problem' of handguards with full picatinny rails. Basically, it's fairly pronounced and can feel a bit uncomfortable, almost even 'sharp'. That's worth noting because I feel both are quality products made of the same 6061 (T6) aluminum.Īs you get into the longer BCM MCMRs, however, the price does get more competitive with Aero Precision.Īnother thing I don't like about these handguards is that the top rail doesn't 'blend' super well into the rest of the handguard. They have both M-LOK and KeyMod variations for all of their handguard designs, but we generally recommend M-Lok as we explain here. In our own experiences along with everything we've seen across the internet, their quality control is excellent, as is their customer support in the unlikely event you have any problems.Īll of Aero Precision's free float handguards are made out of 6061 (T6) aluminum, which is generally the standard material across the industry. They manufacture their own receivers and handguards in house, which has led to them churning out parts in bulks. If you've read our best upper receiver and lower receiver guides, you've seen that we're big fans of Aero Precision when it comes to affordable, high-quality AR-15 parts.

We'll be grouping our choices for the best AR-15 free float handguards by manufacturer, starting off with some budget options, then going onto some higher-end handguards. As we discuss in detail below, we highly recommend opting for a free float handguard, as opposed to a drop in handguard.
