Looking for some advice on my latest build. I’m using a 16” midlength gas Craddock Bartlein barrel with a 0.078” gas port. The build will eventually be suppressed with a Huxwrx Flow 556K and I plan to use a Vltor A5H2 buffer with a Springco green spring.

I didn’t plan to use an adjustable gas block because I didn’t think it would be necessary with the above setup but one of my buddies told me it might be slightly overgassed even with the Flow 556K.

This got me thinking about the LMT E-Carrier which I admittedly know very little about. Would this carrier be a good fit for this build? Would it’s gas blowback reduction qualities be enough for me to skip an adjustable gas block all together? I’ve just had bad luck with carbon locked adjustable gas blocks and I want to avoid them again if I can.

I like the IMI Razor Core 77g so that’s probably what I’ll be shooting most of the time.
