It’s a sticky wicket mate
I’ve tried MWS charging handles in my systema mk18
they work but some require modifications due to the hop unit you’re using and type of cylinder
If your fitting the Jaeger Npas into the DE nozzle
you modify the NPAS not the bolt carrier or the nozzle.
Or just replace the DE nozzle with a Tm one or G&P spec then the Npas will fit right in.
I fitted the Jaeger into my partners mk18 and worked flawless
fitted the Npas to my L119a2 and constant 1.1j on .32s using propane
Not a chance 2k base price.
if you are on about because it’s a £2400 build then my systema PTWs should be near £3000-£4000
my mates one sold for £1200 with RS EoTech, 6 stanags steel bolt, modded motor
there is one for £900 with 6 mags and uprated parts. URGI models are selling for £1100
If it’s soft and squishy
have a look on YouTube for a video that explains how to modify the hammer and check the sears.
they are over moulded from factory so after time they give the feeling of the dead trigger
yeah the chassis only needs very light greasing and the piston needs oiling every 20 mags or so for it to be decent.
What type of feeling do you get from the trigger?
soft, squishy or does it just feel like a dead trigger?
has the chassis been removed fully cleaned and lived lately?
tm Mp7’s are known for intermittent working if they are over lubed.
the seat sometimes fails and the steel sear is a good replacement if can find one.
All dependant on the parts list.
on my old WOC Build I shimmed the stock Routers to the old 5ku nozzle.
some people modify a GHK nozzle and seal to fit the Wa Bolt etc which in turn lead to more issues down the line.
It all depends on the current setup
if the pistol is great with gas efficiency like Tm and some WE models..
adding an updated router will need some supporting mods like re-enforced nozzle and return springs piston seal/cup.
if the gas system struggles from factory with efficiency due to a poorly designed nozzle and Mag seal, then it will act like you run it on propane.
my advice is to actually shim your current mas seals and test how it improves it.
It’s just mag cool down mate.
easiest thing is to get pocket hand warmers and put them in each mag pouch, keeps the mags over 18° easy and allows the gas to perform like it’s summer
Can I get someone’s input..
I have a BCM bolt with a GM 3.5 nozzle and Npas, Waldo nozzle spring, dynamic Npas spring and it feels like it’s getting hung up more comparing it to my second Tm bolt running the same set up just a G&P nozzle.
The BCM bolt releases the nozzle way later in the cycle motion.
would running the G&P nozzle be better long term using propane?
