  1. Why do yโ€™all use a .080 port for your 16โ€ mid barrel? Thatโ€™s definitely not ideal for Shooting suppressed, and now I have to get a freaking BRT tube to bring it down to about .073

  2. Dude that has got to be the best no bs video!! I wish they would keep making more to cut through all inter web operators!! I have to know what mount is that with canted reflex?!?

  3. Hello, what is the barrel length on your AR -15 in this video? Thank you. And what is the best barrel length and gas system for suppression? I have now 12.5 carbine gas.

  4. I have a 13.9 Core which i like but it doesnt like running some ammo…I usually like more reliability in gassing but anyone see this? or maybe should i use a H buffer with lighter spring? Doesnt like steel case and some others.

  5. Superlative Arms adjustable gas blocks. I have about 7 over the last 3yrs. Legit good. Adjustable gas blocks also come in handy when shooting different grain ammo. So, yea you need one. Apparently you don't but they are worth the $100 investment.

  6. I have a voodoo witch doctor ar-15 what barrel that will take a suppressor permanently or one that has a thread would you recommend ? Iโ€™ve never built a gun before just bought it and put small shit on it

  7. I see you have a nightforce 1-8 in this video and some others you have a razor 1-10. Which do you like better? I have a bcm that I just but a criterion 14.5 core barrel on and trying to decide which optic between these 2.
    Thanks

  8. How dirty does it get after a full combat load 210 rounds? Has it gummed up where you needed to use your forward assist? I was looking at building a slick side for less gas in the face as a lefty.

  9. Adj gas blocks need maintenance and can and do fail..I have not had the leaf spring problem with their up-dated versions.., The new rifle speed adj gas block looks like a game changer for durability and ease of maintenance. A .003 spread is perfect from a 1.4646 and a .001 difference with an AR bolt is also excellent..Having a tight gas ring bore is good but I find the bolt tail to bolt tail bore clearance more important for an optimum gas seal…Just ordered my first Criterion barrel and looking forward to testing it. Your barrels must be good as they are months on back order..

  10. Thank you for the information! Would a white Sprinco buffer spring be closest to the mil spec unit you're running in this rifle? Also, if you're using an A5 system, would a green spring and H2 buffer be optimal for the mid length system?

  11. With the Badger Ordnance TDX gas block did you dimple the barrel deep enough for the screws to seat flush with the bottom of the gas block or leave some screw sticking out of the bottom? I installed my TDX on a Core 16" barrel and was worried about dimpling so it has a bit of threads showing still.
