The FPS limit on under 18s effectively removes the advantage of using a bolt action completely, the result of which is to dissuading teenagers from playing using high FPS longer range bolt actions.
 
If you are still wanting to play the role it can be done but only at a massive disadvantage. It is as simple as fitting a lower powered M110 spring and potentially cutting it a bit. But I wouldn't personally do it because single shot 30m single shots with bolt reloads is going to find it hard to compete with full auto fire.

okay so now i am more open to h&k 416's. im looking at the g and g t418 and the umarex HK 416. any experience/ advice

Yes ive got the T4-18 Gen 3. Nice rifle. Some have been talking on here a out MOSFET problems but I havent experienced it on mine.
The T4-18 is supposed to be a H&K 416 rather than an M4.

thanks for all the great replies. ive been thinking about getting the G&G t418 ( http://www.airsoftworld.net/g-g-t418-airsoft-rifle-with-blowback-gen-3.html ) or the G&G GR16 R4 carbine ( http://www.airsoftworld.net/gandg-gr-16-r4-carbine.html ). has anyone had any experience with these or has heard about them.

Here's a list of a couple of guns from wolf armouies it's a pretty good shop it's where I've brought all my gear from.
 
G&P enforcer- http://www.wolfarmouries.co.uk/airsoft/bb/product.asp?page=product&id=GP744
SRC m4 SR4 SD- http://www.wolfarmouries.co.uk/airsoft/bb/product.asp?page=product&id=GE0509TMII
SRC m4 SR4 - http://www.wolfarmouries.co.uk/airsoft/bb/product.asp?page=product&id=GE0512TMI
Dytac invader - http://www.wolfarmouries.co.uk/airsoft/bb/product.asp?page=product&id=DYAEG07BK
G&P m4 sentry - http://www.wolfarmouries.co.uk/airsoft/bb/product.asp?page=product&id=GP901M
 
They also do packages where you get 2 battery's, a mag, silicone and a chargerfor £99 http://www.wolfarmouries.co.uk/airsoft/bb/product.asp?page=product&id=98XPSBAEG
 
I have the G&P enforcer which is the top link I put and it is a amazing gun it comes with a red dot sight and a vertical grip it shoots really fast and is a solid gun with with no wobble at all. I spend about £430 and got the gun a extra mag and then the battery package. You might want to spend a little more then £400 as you need a mask and a tactical vest if you want one
 
I have this vest and it's pretty good- http://www.amazon.co.uk/USMC-Tactical-Assault-Airsoft-Olive/dp/B0041300WK/ref=sr_1_2?ie=UTF8&qid=1425213722&sr=8-2&keywords=Airsoft+vest

I don't see how you couldn't have a full metal receiver if you're spending £300+
It's not so easy to say because there are so many airsoft AR-15 style guns.
 
I'd recommend one of these (http://uk.redwolfairsoft.com/redwolf/airsoft/AEG_AEP_Magpul_Magpul_PTS_RM4_CQB_ERG_Black.htm / http://www.landwarriorairsoft.com/airsoft-weapons-c38/electric-rifles-c45/pts-pts-rm4-cqb-erg-p3303) they're within your budget but there's only the CQB version in stock.
They are awesome from what I have heard, and plus you get the recoil / vibration.Yes it says CQB and is shorter but in airsoft, it's actually the barrel quality that matters more than the length and bore. So you will probably have the same performance as the Scout version anyway.
Plus I know there's one or two guys on here who have one - I was going to buy one too but decided I'm going to buy an AUG then get a GBBR M4.
 
If 416s are your thing:

Have a look at G&P too, they start from around £250

come up with a short list of ones you like and Im sure the forum would be happy to advise on their experience.
