Not seen one like that before! Pull it out and stretch it a bit. Use a pair of fine nose pliers to pull it.

I had this happen - if you get some 2.5mm spade connectors for crimping (with the red plastic ferrule on) you can crimp them on then remove the plastic with a pair of cutters. Sleeve them over with some heatshrink and Bob's your uncle.

The bolt cover plate is mostly aesthetic, it does keep the crap out of your hop though so if yo're going to run without it, keep an eye on the hop and make sure it doesn't get all cruddy. Not sure what you mean with the spring to be honest (my M4 doesn't have anything like this). I use locking pins that have a screw on cap on the opposite end to the head of the pin. Works fine - no spring, nothing. http://www.fire-support.co.uk/product/guarder-m-16-enhanced-steel-retainer-pins-m4-m16

If you can't find the connectors you want from Farnell then they probably don't make them. That said, an RC spares shop might be a better bet. Also - go find your local Maplins. Which connectors are you looking to replace? The motor ones?

Some guns have O rings placed along the barrel to centre it. These usually end up getting pushed up to the front end of the hop up unit as you put the barrel in.

I think it's a simple fix, whether or not you think it is may well be a different matter! If the bolt cover plat is popping out when you pull it back then I am wondering if it's slightly bent out of shape? They're incredibly flimsy things. Also - who put the yellow tape in there and why? The bolt cover just doesn't look like it's in quite right. As you pull it back it looks like it's popping out of the little rail along the side of the receiver. Does it only do this when you try and do it with the gun apart? It's frustrating because it probably is a really simple fix but without getting my hands on it I just can't really tell exactly what's going on. Sorry.

Why do you want to build your own MOSFET? Also - CPC won't sell 3" bits of wire, you'll have to buy a whole reel. Personally I'd advise you to buy an off the shelf MOSFET which is tested and proven in the market. Gate, Burst Wizard etc all make decent hardware for not much money.

If the site had called the Police it would still only be up to the individual concerned as to whether or not he wanted to press charges. Personally I think it would be somewhat of an overreaction if the site called in the Police unless some serious level of harm had been done.

Also - with the upper not going all the way back, is the gun front or rear wired? If front, take a look into the magwell and check the wiring isn't fouling the hop unit.

Can you take a pic of the inside of the receiver with the plate and charging handle in? I can't really tell what's not right from that.

From that picture you've got the plate on the wrong side of the charging handle extension It needs to be between the handle extrension and the receiver.

See - this is the other thing I like about you. You get all of a lather about some shiney new thing, someone says "don't be a dick" and you say" oh..OK then". We likes n00bs that listen

Or indeed the most epilepsy inducing

Right - it's bit of a faff but I'm guessing there's a little groove (probably a stuck on strip of rubbery plastic) just below the ejection port hole on the inside of the receiver? With the upper receiver off and the barrel etc well out of the way you need to place the ornamental cover into the receiver making sure the end of the charging handle engages into the edge of the cover (so that pulling the handle still pulls the cover back). Gently slide it into place in the groove and you should be all hunky dorey again.

Good luck with the shimming! I tried, failed, put the original gears in. They stripped, fitted SHS Super Shooter flat gears and now it's way quieter than it ever was! Thing is that IF you can get the shimming dead on helical gears are pretty much silent. Getting the shimming spot on is the tricky bit!

When your sig is bigger than the post...it's time to rethink your sig.

You can also get ones with slots cut in the side to simulate muzzle flash. Works better than the ugly ass PoS in the OP.

Quieter gun eh? In that case you'll want to look at shimming it properly and maybe a different piston head. Sorbo pad to lessen the impact noise (which will then pretty much force you to do an AoE adjustment - no bad thing).

Gunman Eversley still do Flying Lead Filmsim days (this one was in February this year - https://www.facebook.com/events/606432199400121/ )

Flex. Flex, Flex, Flex. How do I put this..... You've just started (YAY!), you're enthusiastic (DOUBLE YAY!) and you have aspirations of greatness (HUZZAH!). BUT - you have just started. Setting your sights high is one thing. Saying already that you simply must have a training weapon is pretty much the equivalent of a guy driving around on P plates asking everyone about the service intervals on a Lamborghini. By the time you've been playing long enough for your CM16 to be the limiting factor in your games you will almost certainly have realised that actually a better G&G or indeed the Marui Recoil range is more than good enough for what you want. Nothing wrong with aiming high, nothing at all. Just maybe get a bit more play under your belt first to prevent going off half cocked...

In all these situations I do my level best to take the high ground and just walk away. The other guys just reinforce to the marshal that they're the ones being idiots plus life really is too short to get that aerated about a game of soldiers in the woods. Walk away, move along, get on with having fun.

Helical gears are usually recommended when you're trying to increase FPS rather than RoF. They have a greater meshing area on the gears which allows them to consistently produce stringer torque. If you're after increased RoF I'd stick with good quality flat gears (SHS Super Shooter, Siegetek, Lonex etc). There'll be plenty of other things to absorb your cash if you're going down the high RoF route!

I use napalm and a scotch brite pad. Of course... my guns screwed but it's shiny :-)

Helical gears are a pain to shim properly. If you get it right they're near silent. If not they sound like a cat eating wasps. In a can. Going over a waterfall in a dishwasher.
