Double up instead of limiting yourself!
Many shooters prefer to use a 30-round magazine, but are not allowed to use it due to various requirements or regulations.
The new magazine couplers from RJK Ventures now offer a practical alternative to the limited 30-round magazines.
So any two Magpul PMAGs can be connected with this coupler; Two 10-round magazines are very similar in handling to the usual 30-round magazines and make reloading much easier.
The magazine couplers meet the high quality standard of Magpul PMAGs and are made of the same solid nylon. Assembly is quick and easy and connects the magazines reliably and without play.
