"The TAC21 chassis certainly lives up to the first word of the company’s name. Modular. You can accessorize this stock just about as much as any AR-15. Grab your favorite AR-15 buttstock and grip to complete the rifle. Or, you can purchase MDT’s new skeletonized buttstock that was specially designed for the TAC21 and LSS. A 20 MOA continuous rail along the top provides plenty of space to mount your optic wherever suits you best, along with any other add-ons you might have. Even with the long Premier Heritage 5-25, I still had enough space to throw some night vision in front of it. Holes to mount additional pieces of picatinny rail line the sides and bottom of the handguard, enabling the use of the Atlas bipod and whatever internet gadget you can find. There are also screw holes to mount a piece of rail on the left side, closer to the center of the stock. This can be useful to those of you running any sort of laser designator in conjunction with your night vision. Having it mounted closer to the center keeps it from becoming even more front-heavy with the night vision already being there, as well as being much easier to reach and manipulate."
