We use James Madison Tactical composite lowers because of their strength, light weight, durabilities, and absorption shock. They’re also much easier and quicker to mill out than aluminum. We also include all milspec lower parts, and a Strike Industries Mod1 butt stock. A Magpul Moe K2 pistol grip also is included. Due to certain state laws these kits do not include magazines.

The HS503GU is a red dot sight that features a 65 MOA circle with a 2 MOA dot reticle. The housing design shrouds the windage and elevation turrets on two sides. Employing LED technology, the life time for one CR2032 battery can reach 2 years if left on constantly. However, the motion based automatic on and off feature extends the battery life dramatically beyond that for the average shooter.


Holosun HS510C Reflex Sight 1x Selectable Reticle Weaver-Style Quick-Release Mount Solar

  • Switchable circle/dot and red dot reticles
  • Always on unless manually turned off

Here at Cougar Innovations we see this sight as being the best bank for the buck rifle red rot. This sight is absolutely awesome because it’s amazing battery life and crisp dot visibility not to mention it’s selectability between a red dot and red circle.

The HS510C Reflex Sight has an open frame for a wide sight picture. Always on, it is powered by solar cell under normal usage, and a back-up battery to supplement power requirements in low light conditions. The reticle can be switched between a 65 MOA circle with 2 MOA dot, or a 2 MOA dot only at the push of a button. Better yet, the same LED projects both reticles, so no re-zeroing is necessary.
