It uses the same outer toob and adapters as the OP9, but optimized for smaller bores. Off-axis bore means no need for suppressor height sights.
Also, LOOK MA I CAN POST URLS NOW
we are interested in the potential of this design. how well (does it) cycle with 5.7x28 on tilt-barrels?
The tester who ran it on his psa rock said it cycled well. Chat on matrix?
random question, has any testing results come out for the Gustav? Tried joining the matrix but the main server seemed down
not sure why you are having trouble joining. but we use element. the biggest thing with the gustav is that it was meant to just be a flowthrough version of the ratte with a little added length. it won't be as quiet as them on a similar weapon, but it won't produce nearly as much gas. testing has yielded results consistent with these design principles. sorry to OP to hijack the thread by the way.
