The AMBI-CATCH(tm) is a patented drop-in replacement of the original
magazine catch for M16A2 Rifles, M4 Carbines and other firearms that use
an M16 type magazine.
installed, the Ambi-Catch(tm) also gives both right and left-handed
shooters the flexibility to choose from several different magazine
It is one of our favorite ambidextrous mag
catches for the AR15/M16 in the market. Indeed, the idea of an improved
bolt catch was conceived when we started using the Ambi-Catch more than
a decade ago, the idea went on to become the ABC/R (Augmented Bolt
Catch / Release)
ABC/R (Augmented Bolt Catch/Release) with its angled and larger top
paddle and lower paddle with increased surface area, is purpose designed
for use with AR15/M16 receivers equipped with ambidextrous magazine
Specifically, it is designed to address the difficulty with accessing
the factory bolt catch's lower paddle with an ambidextrous magazine
catch, such as Norgon's Ambi-Catch, on the receiver. Many of the
ambidextrous mag release's lower paddle is on the same vertical plane as
the factory bolt catch lower paddle, making identification difficult by
feel, especially with a gloved hand.
Starting from June 15, 2018, bolt catch spring, roll pin, and plunger are inlcuded.
Please note the ABC/R and ABC/R-F
are not designed for use on 9mm receivers that use Colt 9mm magazines
which require a Colt 9mm bolt catch, or 7.62mm receivers.
