Just looking for thoughts on this, I have an AAC M4-2000 coming and have a Noveske light basic with the AAC break on it ready to go. However, this is the standard upper and not a switch block upper.
Is there any real reason for me to have to spend another $1400.00 plus on a complete switch block Afghan upper for my suppressor to really work well? Thoughts from any suppressor/Noveske owners???
ThanksâŚ
People where running suppresed uppers before the switchblock was around 
Itâs not the intention of the Swithcblock to make an upper run, itâs to change the way it runs when suppressed.
My 10.5" Noveske barrel runs just fine with anâ06 M4-2000 on it, and no switchblock, but is likely running faster than it needs to, or should.
The SB helps to tame that âextra actionâ.
does this âextra actionâ do anything to my 14.5" barrel or not? Wondering if it is going to wear faster or not? Obviously it is going to be dirty no matter what, does the switch block help keep it from getting as dirty or not? Decisions, decisionsâŚ
You are moving your parts faster when suppressed, it stands to reason they are wearing some fractional % faster. Enough to worry about? I donât lose sleep - at all. Doesnât make me right, just means I donât sweat it.
Completely your call.
well since my gun is just a semi auto, I am not really that concerned that it will wear any faster. Now if I was running full auto, I may be concerned. I am looking at one of the railed uppers with flip up sights and the price difference in getting the switch block and not getting it is about $100.00.:rolleyes:
Itâs nice but not required, especially on a semi. You can upgrade the buffer and or spring to handle the extra gas. The Swithcblock negates that need, plus it helps keep the working parts cleaner.
It doesnât matter if you are shooting semi-auto or full auto. The parts get beat up because of the pressure that is diverted back into the weapon.
IMO on a 14"+ gun you can just install a heavier buffer and be good to go supressed.
ETA: not that the lighter buffer wouldnât work, itâs just the heavier buffer will help slow things down a tad, reducing parts wear.
so are we talking an H2 buffer then???
H2 should do ya fine, you could try an H3 aswell, but that might choke on lighter loads (only one way to find outâŚ).
