Finally got a break in the rain and was able to hit my BLM range to test three of the M4 H2O's and get them sighted in. The three up for testing riding in the Pelican 1750. What's interesting here is there are three different magazine tube configurations. More on this in a bit. The overall goal was to sight them in with slugs at 50 yards. I use a laser range finder to get the distance right on my B27 target stand. I then have a lead sled that I sit on a folding table with a chair behind it to take as much of the shooter out of the equation. Once they were sighted in, I ran about 25 rounds of buckshot and 50 rounds of birdshot to test out how each is performing. First up for testing was the center M4 with a Trijicon SRO 2.5 moa dot optic and a titanium magazine tube. Function was flawless and I had it doing head shots on the B27 within 6 rounds. Ouch. Up next was the OD green M4 with the Trijicon RMR 1.0 moa optic. My personal favorite. This one has the lightweight carbon fiber magazine tube. Iron sights removed to cut weight. Sighting in was just as easy. However the groups were slightly larger than I was seeing with the titanium tubed model, which I didn't photograph. Function was flawless for the remainder of the tests. Blew up a lot of random crap in the desert with it. Third up was the H2O with the SRO 5.0 moa dot optic and the steel OEM magazine tube. 5.0 moa is massive. At 50 yards, the dot filled almost the entire head of the B27. Problems emerged immediately. The firearm was having issues loading the last round from the magazine tube onto the carrier properly. The round ejects onto the carrier partially, but then the elevator cannot lift it to load it since the front of the round hangs up on the receiver. Diagnosis for this is a shitty magazine spring. It'll be swapped out with a carriercomp spring. I continued testing anyway since the malfunction only appeared every third time or so. Even with the monster 5.0 moa dot, the steel magazine tube was much more rigid of a base and permitted me to make some incredible groups. This was the first time I've shot one of those Benelli compensator breeching chokes. I didn't notice any real benefit in recoil reduction. I did notice the extra 7 ounces of weight on the end of the barrel. After cleanup of the site, 90% of the shells were mine. I went thru quite a bit of 12 gauge! So the shotgun is probably more accurate with the steel magazine tube. Not enough to really matter at shotgun distances. I'll still stick with the carbon fiber magazine tubes on mine since they are much lighter up front. I would not use the breecher choke unless I absolutely had to for some outlined mission objective role. The SRO is much more forgiving for your cheek placement than the RMR. Smaller the dot the better. The smallest dot isn't any harder to find than the largest one. So it comes down to how much of the target you can tolerate being obstructed.

If you had a YouTube channel with this type content I imagine it would be pretty successful You're already doing the photography staging, and you wrote a script here for this post. Just pointing out an opportunity for an additional income stream

That looks like quite the fun day.

Carrier Comp order for 7rnd titanium tube (parkerized) placed 03/20. Just received call for payment today (07/27). It will ship out in 3-4 days. So if any of you guys are waiting for tube, they are still working down the list!
