RT15 Poly Complete Lower Receiver

The RT15 Poly complete lower features a uniquely lightweight and sturdy design.

For marksmen with heavy optics and accessories ranging from bipods to suppressors, every ounce of weight savings can count. This is especially true if you ever plan to hike with your rifle to hunt or carry in the wilderness. Tactical shooters who enjoy shorter barrel lengths and smaller optics appreciate the lightweight lower as it allows for quicker handling, and will fatigue your arms and shoulders less when holding the rifle at the ready. Do yourself a favor and start your next build off by saving precious ounces on the lower receiver, as forged or milled lowers need expensive machining and skeletonization to reduce their weight.

This polymer lower does not need to have its castle nut tightened, torqued, or staked, as it is factory torqued to 6-8 lbs with blue Loctite and will not come loose.
