STNGR Ambidextrous Lower Parts Kit

The STNGR Ambidextrous Lower Parts Kit makes any mil-spec lower more modern and ergonomic than the basic LPKs flooding the internet. This kit includes an ambi safety with a positive 90 degree throw, plus an ambi mag catch for quick changes on your strong or support side.

An Ambi LPK is a must for left-handers. This kit will allow you to get more out of your AR without having to spend a ton on specialty left-handed receivers. Plus, for any tactically-minded shooter, having the same controls on either side when moving around cover and obstacles is a huge benefit.

As for your trigger? Pick the one that’s right for you. We know most shooters want to upgrade a nice two stage or drop-in trigger, and we’re not into making you spend more money on parts you don’t need. Even on a more premium LPK, we still want to save you some money.

It’s hard finding left handed kits for AR rifles these days without breaking the bank. This kit contains an ambidextrous mag release and safety lever that I didn’t have to purchase separately. It would be nice if the bolt catch release was ambi as well.
