T91 Lower Receiver


Taiwanese T91 style lower

7 in stock (can be backordered)

SKU: t91 Categories: , ,


This receiver has T91-style markings and a correct 4-position ambidextrous selector engraving with no selector stop ears (but note that the ears were shaved from the original forging in the Colt style and there is still a small plateau remaining).  The legally required manufacturer’s markings are on the reverse side so as not to disturb the original aesthetic.

The mandarin markings on the magwell translate as follows:

5.56 [Mandarin for “millimeter”] T91 [Mandarin for “rifle”]
[Mandarin for “Made in USA”] (The original T91 says “Made in Republic of China”)

The receiver is semi-auto and is otherwise milspec, made from a 7075-T6 aluminum forging from Cerro Forge, hard coat anodized, and does have the M16 pocket cut.  This is the closest you can get to a correct lower receiver for T91 upper receivers, such as the Wolf A1.

To complete your new lower, one of the most important parts is a genuine T91 pistol grip, now available HERE!

Also included with this receiver is an IR Reflective Taiwanese Flag patch in authentic Taiwanese DCCU camouflage.  This listing is for ONE (1) STRIPPED lower receiver and a patch.  Pictures displaying anything more than a single stripped lower receiver are for display and suggestion only.

This is legally a firearm receiver and can only be purchased by individuals 21 and older, and must be shipped to an FFL.
