Sounds like your sears are knackered, an all too common fault with the AGM rifle, they fit way too big a spring for the monkey metal trigger parts. You need to fit upgraded VSR10 steel sears.
Edit - There IS a bodge for it (only temporary mind you). You need to remove about 5mm from the slot that the piston sear moves in. In the picture I've attached (taken of the almost identical TM VSR trigger), I've coloured the bit you need to remove in red. I hope it helps you.
When I want your opinion - I'll tell you what it is!
Been working with a master carpenter and he cant see any problems in re creating a smle stock. I'm buying a JGbar 10 to lend him to see if he can copy the stock and cut it to fit bar 10 internals. I pulled a smle out of the armoury at the range this evening to take some photos for reference.
Sorry to be pedantic, but that photo is a No.4. The term "SMLE" is usually used to refer to the WW1 version that became the No.1 MK III and was largely replaced by the No.4 during WW2.

I stand corrected. Thanks 
Yep! the same thing happend to me with my build..Had to swap internals and now i regrett that i stuck another AGM mp001 in it!
If you do the bodge, it IS reversible, basically, by bodging it again! Either with Milliput or some liquid metal epoxy.
Best place in the UK for VSR upgrades is Firesupport. They actually get fresh stock in when they run out!

Same thing happened with mine, was shooting like a dream up until that point!
The best advice I can give to anyone Re:the MP001 is DO NOT BUY ONE unless you are willing to spend another £50 or so on new trigger parts almost immediately.
It's much better in the long run to spend the extra on a JG BAR10, which is 100% VSR compatible and much better made. This is my opinion formed on bitter experience with the MP001 and I now work exclusively using the BAR10 or the VSR10, which are much easier to source parts for and have a far superior HOP to the MP001 as well.

Cool, might have to switch it out when I can get hold of 1 then!
Of course, the VSR/BAR has a couple of faults as well. The biggest one to watch out for is the trigger housing screws (where it attaches to the receiver), when the gun is upgraded, the front one of these has a nast habit of stripping its' thread, meaning the gun won't cock and this problem manifests itself by the gun slam firing, so, at first, you think the sears are shagged.
Another niggle with the BAR/VSR is the size of the receiver and cylinder tube. They are much bigger than those of an MP001, which means more hollowing out of stocks in order to get them to fit.
When I want your opinion - I'll tell you what it is!
Well.. I'd buy a real sight and then make something to hold the base. You'll not be able to make something that looks as nice yourself.
BTW, the gun looks good so far. I really must post some pics of mine!

Still a bit stuck on the best way to fix it to the outer barrel though.
How about silicone sealant? It'll stick, but you can get it off if you need to.

Rather than fix it to the outer barrel, fix it to the upper handguard or use the handguard to hold it in place.
looking a LOT better than you suggested on the phone. Keep going !
very nice,, i like it. how much has it cost so far?
genius
Bloody excellent work, just goes to show you don`t need to spend big bucks, just the application of a bit of imagination and some diy skills, superb !
Looking good. You started on mine yet ?
I did have a thought, what with all of the FPS talk on the Ariel threads. Are you still going to be able to strip it down and upgrade or replace broken bits ? Being as mine is the same Chinese knock off as yours it's likely that the same problem will occur and I'll need to strip it to fix it.
Wouldn't FPS change be a matter of removing the bolt and changing the spring? Not sure how hard that would be, though.
