I’ve had this rifle for about 6 weeks and have about 500 rounds through it without any real stoppages, except during a rifle match, when a round popped out of the top of a magazine on a bolt open reload.
Some things that might not be apparent from the pictures:
There is very little aluminum in the design. The picatinny rails, barrel support, and selector/safety are the only aluminum parts on the rifle. Everything else is either steel or plastic.
It’s bulky but light. The rifle is very deep from top to bottom but pretty narrow. Most of the space forward of the mag well is hollow plastic around the barrel, gas cylinder, and forward nose of the bolt carrier.
Rifle with stock folded with sling attached. Finding a way to mount the sling is kinda a pain. The built in sling mounting points are too narrow to work easily with 1” slings. My solution was to use paracord loops to attach to HK hooks. That also helps with noise, is flexible, and is easy to remove.
Rifle field stripped into 3 basic groups: upper receiver, lower receiver, and bolt carrier group.
Upper receiver strips down to the barrel and receiver body.
Receiver details: Internal rail cuts on receiver. The steel BCG runs on plastic.
Receiver from below. I have no clue how they molded all those details at one go.
Front of receiver/barrel support. The aluminum barrel support has 3 legs that locate it in the plastic upper and a steel insert with sprung fingers that actually contact the barrel at the gas block.
Barrel details:
Barrel extension.
Bottom of barrel extension with wear from the barrel latch is apparent.
Top of barrel extension. The dished out area is clearance for the bolt carrier control pin spring.
Detail of the moving gas cylinder and stationary piston. The two spring tabs retain the two caps.
View into the lower receiver from the top. Visible is the center tab that activates the bolt hold open, the to side pieces that actually hold the bolt open, the green plastic hammer body, the steel hammer, black plastic trigger/sear, disconnector, drop safety, and the take down plate/ejector selector.
