Recessed 300BLKOUT build Q's

[Butter.Actual]

Hey all, I'm new to these forums and I need to get some good posts in so I can access the classifieds, so I figured I'd pick everyone's brains to make my next build a whole lot better

First off, what I've got laid out so far
ADM blem lower, criterion 8.5" 300 barrel, VLTOR A5 buffer system, surefire OBC, SLT-1 trigger, and potentially a Raptor SD

So my questions are:
What's your opinion on the raptor SD and in your experience, did it negate some of the gas that blows into your face (I already expect it to suck as a lefty, so imma do everything I can to minimize it)

I havent picked a rail, do you have any suggestions for one that would fit a 1.5" OD suppressor cleanly (12 inches preffered)

Is there any specific reasons you dislike recessed suppressor builds?

General AR chat/things to look into would be much appreciated

i have build a 300blk where the flash suppressor sit inside the rail. if i want to shoot without the can, i install the blast deflector and it clears the rail. MI was the only rail i found that fit my needs https://www.midwestindustriesinc.com/product-p/mi-sp12m-blk.htm
10.5 bbl with yhm QD and deflector. Raptor=ehh for me at least.

I also wanted to do a recessed suppressor build with my 300 blk SBR but it is quite difficult finding handguards that will accommodate a suppressor of that diameter. Most aftermarket handguards tend to be in the 1.3" range, so I gave up on that idea and went with an SLR Rifleworks handguard that runs a few millimeters shy of the threads.

I don't have any experience with that particular charging handle, but I went with a couple other options to reduce blowback and I've been pretty satisfied with the results. The first was a Superlative Arms bleed off gas block which is designed to direct excess gas forward when shooting suppressed. It's now my go-to adjustable gas block for builds. The second was a LMT enhanced BCG. It has extra ports to redirect excess gas away from the shooters face. Both are a little pricey but worth the money IMO. I can fire freely while standing without being gassed. The only time it really happens is if I'm hunkered down over the rifle shooting at longer distances.

Edit: Forgot to mention...the VLTOR system is good but the JP silent captured spring system with the spring kit is worth looking into.

Thanks for the tip on the gas block, I'll definitely grab one to check out, and I've looked at the captured springs and such before but I have friends who have too much time and money who have figured the VLTOR system to a T, so I'll obviously be sticking with it

Thanks for the reply mate!

Any reason for it being ehh, or just seems overhyped

Yankee Hill makes hand guards that have a large enough inside diameter to fit suppressor. Linear comp works when suppressor is off.
Yankee hill on both one is 10.5 the other is 7.5. Both 300blk

I can't remember who makes it but somebody had a short barrel .300BO with a permanently attached "muzzle device" that allows you to tuck your can in and still be over the 16" rule so you can run a stock and not have a SBR.

Let me see what I can dig up.

Edit: Found one. This is the whole upper.

Just an idea to think about.

KAC urx4 rails will fit a suppressor underneath so will Troy ind. MLOK rail. I have the 7.2" Troy on my 6" 300blk the suppressor sets about 1.5" under the rail.
