Thanks all for sharing the niggles and quality issues some of you were having.
I have checked over mine and everything appears all good so far, well... apart from the below.
As
@Fubar had pointed out previously one of his Kicker arms was bent and resulted in making contact with the playfield. Well I also have an issue with a Kicker Arm making contact with the wood, although this is not because of a bent Kicker Arm.
Carried out some inspections. Here is the damage to the wood from the Upper Right Kicker Arm on the Slingshot in the Reactor Core, and what I have found so far.
Upper Right Kicker Slingshot Arm is sitting to far forward making contact with the wood, I would say this is sitting approx 4mm to far forward to front edge. Photos below show Kicker Arm at full travel and the damage to the wooden edge where it has been making contact.

Now when looking further into the assembly I cannot see any loose Kicker arm, bracket, coil etc. Everything appears to be fully secured. Suspecting a build quality issue at the moment, the assembly has not been fitted correctly to ensure the Kicker Arm is lined up in the centre hole in the wood on both the horizontal and vertical. Kicker Arms mounted to far forward can result in damage to the wooden front edge.
I also checked the Kicker Arms on the other Slingshots and although no damage to the wood, some Kicker Arms are very very close to the wooden edge ( a mm or two) at full travel. Also neither of them are dead centre in the hole, left to right or front to back. I could not find my steel rule so had to use a tape but there are varying distances between the Kicker Arms to the front edge of the hole in the wood.
The maximum clearance seen was with right Slingshot.

Further investigation still needed, as well as finding the best solution to re-centre the Kicker Arms.
I also had a quick look at TNA photos on Pinside, and I seen this from an archived sale advert on an original run TNA.

I also noticed when looking at photos many Kickers Arms are not centred correctly on the horizontal.
I highly recommend that all you owners remove your plastics and slingshot rubbers. Check Kicker Arm is centred correctly and check the full travel of the Kicker Arms.
