Description

The Vanguard_JT is an AR15 lower receiver designed to withstand as many rounds as possible. The Vanguard_JT was modeled from the Vanguard by shadowfall.

*The 45 degree cut of the magwell was originally designed so that the lower could be printed at a 45 degree angle to eliminate the need for support material. Printing at a 45 degree angle is not recommended. It was found that printing the lower at a 45 degree angle will lead to the buffer tube tower breaking in only a few shots. The 45 degree cut in the magwell was kept because it allowed for magazines to be inserted more efficiently. *The buffer tube tower was thickened and lengthened to increase durability. The castle nut and buttstock tube lock are not needed on the Vanguard_JT because of its lengthened buffer tube tower. *The front take-down pinhole was widened to improve durability.

Instructions

*Print at a horizontal orientation as seen in renders *Depending on quality of print, screwing the buffer tube into the buffer tube tower may be difficult. Applying heat to the buffer tube from the inside with a miniature blow torch or equivalent eases screwing in the buffer tube. *Depending on quality of print, it is likely that all holes will need to be drilled out to the correct size *For assembly, Snap Pins (included with files) or 1/4-20 machine screws with wing nuts are recommended. Since the front take-down pin hole is wider than the rear, there are two Snap Pin files included, a Front Snap Pin and a Rear Snap Pin. Under rapid-fire conditions, the Snap Pins WILL BREAK after around 200 rounds. If using Snap Pins, have extras ready to replace broken Snap Pins.
