This comment was generated with the experience we’ve gained over years of building, modifying and researching these and all AR style weapons. Hydraulic buffers are race gun parts. Titanium bolt carrier groups are race gun parts. Nothing wrong with building a race gun, but be prepared to have to work on it for a bit to be consistent and reliable, probably with a very limited selection of ammo choices. Traditional recoil systems that are proven tend to be far more flexible at be able to use a far greater variety of ammo. That is the main reason we suggest them. Easier to add or take weight away from the buffer, adjust if needed or desired, etc.
Some of us here have done more than make a living off these weapons, some have used them to preserve life and or take it. You entered our house. We ask you wipe your feet on the mat and be cordial during conversation here. We aren’t opposed to a different point of view. Realize this is a small community. We want new people to join and contribute. We have information that’s tried and true. If we are not providing the info you’re looking for or you’re question isn’t being answered, maybe it the way you’re asking? Either through lack of proper terminology or just arrangement of words.
