From a right-side bolt release, to multiple adjustment screws to tune the fit and function of your lower to your liking, we’ve not only given you all the features you want, we’ve done it at the same weight as our classic lower“. – 80 Percent Arms
Why Use an Ambidextrous Lower Receiver?
The obvious answer to that question is that you’re a left-handed shooter. A left-handed shooter is certainly better served by an AR-15 designed for left-handed shooters.
An ambidextrous lower gives the left-handed shooter the ability to manipulate their AR-15 as a right-handed shooter would.
One major advantage of the AR-15 platform is that due to the design of the ejector, even left-handed shooters using a right-handed AR-15 won’t get brass thrown into their face.
Additionally, there is no need to learn different control systems when firing your AR-15.
Finally, regardless of a shooter’s dominant side, they can better control their weapon in a variety of situations, such as their dominant hand or arm becoming injured or disabled during an engagement.
Now you can simply move the weapon to the other shoulder and stay in the fight.
The New 80 Percent Arms Ambidextrous Lower Receiver
This premium Ambi lower brings new bold and functional styling to 80% lowers. A freshly contoured design with a host of features gives fresh aesthetics with new functions to the 80% builder space.
We’ve included the ability to drop the bolt from the right side of the receiver, aiding in speed reloads and getting the shooter back on the gun faster.
80% Arms has incorporated several other features to improve shootability of the lower receiver as well. A trigger pre-travel take-up tension screw has been included to improve the pull on triggers that may have excessive pre-travel by providing upwards tension on the rear of the trigger unit.
Additionally, a receiver tension screw is included with the receiver, allowing for tension to be placed on the rear takedown pin lug of an upper receiver, removing slop or movement between receivers where the aftermarket match may not be as precise as desired.
Because even the little things matter, 80% Arms has threaded the rear takedown pin spring hole, to make installation of the lower parts kit (especially the backplate), a breeze.
Finally, the rearward safety selector stop has been abbreviated to allow easier manipulation of the safety selector when hands are wet or slippery by allowing more thumb engagement on the safety selector lever.
