Nonsense. What you describe is improper use of the Keymod rail. If you are having those results you are doing it wrong.
Nonsense, it is absolutely possible to avoid interference of a picatinny rail and gas block either by positioning the rail differently, choosing a rail with different stud spacing, or a rail with the newer shorter Keymod studs. . You move the pic rail for the bipod forward of the gas block? That is actually the best position for it anyway. If you must have the pic rail right under the gas block then there are newer keymod nuts that do not even protrude into the handguard tube area.
The two settings on the Switchblock do not constitute and adjustable gas block. The Switchblock was innovative when it came out but is totally surpassed at this point.
A couple things to consider:

Uhg, that gas port is disgustingly big. I hope my 16" is to proper spec. Thanks for showing me those threads, they were a good read.
On a different note - what about flash hider vs muzzle brake? I believe I have read a muzzle brake can affect accuracy? Keep in mind i’ll be running this suppressed the majority of the time.
Not sure if it was Molon or someone else, but I’ve seen where the few ways you’d get a negative affect on accuracy with a muzzle device would be if it was poorly made or was leaving a lot of space between the actual crown and where the device chamber began. Otherwise, the difference was extremely minimal.
A brake mainly helps to stabilize your muzzle, at the expense of increased blast and noise. A flash hider will be much more bearable if you shoot without the can on.
I’m likely going to move away from brakes on anything but shorter SBRs or my Mk12 clones. Shooting a brake under a covered shooting range can be very distracting to fellow shooters. I experienced this past weekend where my dad shot my one Mk12 unsuppressed (waiting for AEM5 to clear) and mine was suppressed. Having his brake blasting over on me was quite distracting, and I do my best to be a “polite” shooter on the range. I don’t shoot my 12.5" with brake unsuppressed without warning folks first out of courtesy.
Why not just get a WOA 18" Varmint with 1 in 7" twist. I got one complete for $610 http://www.whiteoakarmament.com/xcart/product.php?productid=17555&cat=261&page=1 Mine shoots less than 1/2" five shot groups at 100 yds. with 69 grain Sierra Match Kings. I did have WOA Flute the barrel for an extra $100. It runs like a sewing machine.
