No offence, but the reason I enjoy chatting with like minded airsoft addicts on here (and avoid fb etc) is that this kind of stuff is usually not a feature.  
 
 
I must still ask though...  Did you help found UKF?  Your concerns seem to be similar to Robin Page's.

You seem to be doing a good job of demonstrating that you have a problem with women.  Keep digging that hole.

I never stated that you were a right winger; I could not care less what your politics are.  I do, however, apologise for not realising that you were using "snowflakes" as a compliment.

I am sure that you get a kick out of mansplaining to those uppity women; I am sure that it gives them a positive view of you and opens them up to the arguments that you are making.

You did tell us you were a cop too...

I knew someone who claimed to be a solicitor, when pushed he then downgraded it to "well actually I'm a paralegal", bit more digging & it transpired he was only a conveyancer, not a very good one at that lol. 

So you're unable to provide evidence to back up your claim and expect us to all take your word for it

yes that would absolutely do it.
 
the bb in the barrel is a resistance that will slow the progress of the piston (as it works to push the bb out the barrel) so entirely normal for it to be different when there's nothing obstructing the barrel. it's why i tend not to dry-fire aeg's too much.
 
likewise the spring around the barrel pushing the hop unit back is a definite candidate for causing a big air leak if the hop unit is sitting forward of where it should.
 
 
of the precocking options out there there's the gate warfet and perun ab++ wire in the same as a conventional mosfet (ie using the original trigger contacts/cutoff lever etc), although both will require some soldering.

piston slap is relatively normal depending on the particulars of the piston/cylinder head etc. however it might possibly be a sign of an air leak (lack of resistance- faster piston louder slap), very hard to say without actually hearing it in the flesh although you can test on a chrono.
 
twanging is a common enough problem, one way to solve it is the use of a mosfet with precocking enabled, which has other benefits as well folks have also tried things like using a longer spring (of the same rating, so it's under more preload)
