Did the run-n-gun today. First, seems to be a thing. Like, at least a dozen of them, but early days maybe? Seemed like 80% of people here were first time. Check your region.
I have no photos of me because stupid. Unless Foxdie took one as I left the start line and I didn't notice, I totally forgot to have someone take one of me when done and all mud covered. Ruck before:
The only "bad" to the whole thing (to me): Par times. Pretty aggressive ones, so I and a lot of others didn't finish many of the courses of fire. No fun
Good: all else. REALLY hard. I thought I knew what moving 3.1 miles in a ruck involved, but the whole thing was muddy, hilly, under pressure, crawling under stuff, sometimes crawling under stuff in ice cold streams, etc. etc. With waits for others, close on 3 hours, so I got really tapped out for energy, should have brought snacks. It is a pretty good (anecdotal) test of gear, as I got much of it caked with mud, then immersed; one crawl was deeper than expected, so my carbine, and the optics, went underwater.
Had the first stoppage ever on my 16" midlength. Probably from cold range, having to carry it with no mag in lets mud in. Hard to clear, had to mortar it, and on the clock I did it real hard: broke loose the staking on the rcvr extension castle nut. Hand-tightened, did the rest of the course without issue. It's a test. One which scope caps fail! Not me, but this is just one station, and just those not yet claimed (others had been there, I found another!). Push on scope caps pull off also.
No other issues. Nothing broke, lost, failed, stuck, etc. I did a good chunk of one stage's run (through the woods, sliding down hills...) with an M4 mag in a .308 10-speed without retention, by accident, and didn't loose it. Happy about that.
On topic: The ruck was awesome. Did the whole thing with my "jungle" rig as described there and the DG16 over it. As shown in the snowy day above. Had to skip a couple obstacles as the ruck sticks out a lot, or I am weak, but I did a lot of other climbing, shimmying, running, sliding, etc. with it on. No problem in positional shooting, in carbine or handgun. A bit of an issue once getting a the stock on the shoulder as the angle left nothing but shoulder straps, which are so padded nothing would stick.
Little bit of shoulder soreness from carrying all day, probably some failure of integration with LBE straps, as left hurts more than right. Could be all from carbine carry strap as it's just bearing on my neck a lot.
No rattles, no wobbles, not even a snag on the ruck, when running through and under brambles. And I got the sling on the carbine so stuck once I almost fell over. The Crossfire guys got a lot of details right I don't even know, as it was really slick for this.
TJ was a slacker (gamer? and wore some assault pack or other due to the obstacles so will have no report of his own on the ruck. But he expressed some regrets as shoulders alone is a lot of weight for the 50# he had in it.
