Using a spare fire selector you can modify it to be semi auto only.
You can also modify the stock floating valve and make you own npas, covered 20ish pages back i think.
You can adjsut power with all available gasses on a standard MWS from sub 300 to 360
@TadsJ2 can you expand, explain, what product you are talking about?
Theres quite a few buffer products out there!
Nice bit of kit for sure!
Worth noting that what you experienced from the old trigger unit is generally resolved by a good clean out and deburr.
The dead trigger is caused by excess friction from parts that have marred over.
I actually find the old/worn trigger units once sorted out are better than new ones!
The nozzle return spring only breaks through fatigue from extended use, it’s not a necessary upgrade, just a spare to carry.
Only needed to be a genuine one or E6 150% one 😉
If you want to be sure, yes strip clean, inspect and re greae all the o rings / seals, check for any obstructions/swarf, check the force required to push the output valves.
@TadsJ2 your bolt speed is too fast, so the mag empty catch cannot catch in time.
Yes the HSB will help this situation.
Yes unscrew the buffer tube 1 turn at a time and re test.
Low powered duster yes sub 300, but a tightbore barrel and high power gas / propane will net much higher power.
Im not talking a longer barrel either, just a 250mm 6.03 for 330.
If you went upto a 370mm 6.03 power will climb a lot more.
