I’m hoping this is the right place to ask about gear? Saw this image from the ISC a few weeks ago and was curious if anyone has seen this available anywhere. Curious to see if it’s a custom rig or something commercially available. Any knowledge would be greatly appreciated.
Sent about 500 rounds of M118LR through the tube this weekend. No stoppages. Lubed once with CLP. Chewed through the moon dust with no problems. Sounded kind of nasty when the bolt would close. Surprisingly stayed within a minute all weekend. Pretty consistent at 1k, even though it would go transonic at 770m. Only change I think it needs is a new charging handle. The gas was getting to a little too much to the face. Also side note, dope with the M118LR matched my hand loads of 42.0gr of IMR4064. Very surprised with no adjustments. Take a guess where I was lol.
