hello all

started working a king arms p90 to change the full body over to camo.

internals all fine. gun fires etc when testing think its all correct.

however there are 5 long allen key screws. they are almost impossible to put into the body holes . insane force needed and some i can only get half way before stopping


on the original they went through the body and connected to a screw / washer thing on the other side so it was easy.

on the new shell the "washer screws" on one side are fixed and no way to undo them so its just the allen key into a thin plastic shell the whole way

any tips?

thanks
 
Try just the shell on its own. Will they screw in?

If they go in fine on just the shell but not when fully assembling then something about the body vs shell is affecting the alignment by a slight amount
 
took it apart again and screwed them into just the half shell on their own. still super super tight.

i have now put the gun back together and tightened then all 90% of the way and it seems fine.

however in all this commotion i have misplaced a part. any ideas?

That looks like the front of the lower receiver where the upper receiver would slide back over. It would keep the front end more secure than just the latch where the back of the upper receiver joins the middle of the lower.
 
worked it out using the old body.

it is indeed a plate that goes between both body parts right at the front. however i really cant be bothered to undo it all again atm with those screws.

thankyou everyone for the help !!
 
does anyone have an idea of how i can make the last 1/3 of the stock fit together better. the shell has gaps and its now affecting firing as the gearbox is moving. as its not 100% flush

i was thinking of holding it together really tight and wrapping it in camo tape so it holds.

wish i didnt bother with it now.
 
so the rear 1/3 has 4 "mock screws" on both the original and new.

when looking at the old shell these 4 screws do not cross through both sides so not bringing them close together

there were 5 large screws on the original body that ive now replicated onto the new (very tight) . the front 2/3 is now very secure.

its the last 1/3 that is pulling apart and creaking
 
2 x small and 3 x long - the small go at the front of the gun. all nice and tight now. the other 3 are around the trigger area and 2/3

the last 1/3 has the 4 x mock screws. the gearbox i can feel and hear is moving slightly so semi auto is something firing twice or on full. . full auto is fine.
 
The screws (im guessing they're actually in the form of bolts, threaded ?), are either too long, or alternatively the thread holes in the replacement body aren't deep enough ?
Choices are, replacement the screws with a same thread but slightly shorter screw, or carefully drill the holes out a bit deeper with a slightly smaller drill bit, getting the drill size right is most important, as you want the screws to cut in to the newly drilled section.
Or shorten the existing screws (bolts) that you have to suit the existing hole depth, just make sure you pop a couple of nuts on the bolts before cutting, so they can reinstate the thread profile when you remove them, as the threads are easily damaged when cut.
 
inserted pics. the 4 "bolts/ screws" are just mock. on the original they also do not go all the way through but its way more solid / stable

Don't think we're really concerned with the mock screws, the actual Allen screws that hold it together are the issue, can we see a pic of one of those, the full screw please, as well as showing how much it protrudes from the body.
 
the 2 images on the trigger area are from a long bolt that has gone through the body. this is tight and fine.

the last 2 pics are the last 1/3 of the gun. there is no "long bolt" that goes through any part of the last 1/3 pulling it all together.

wondering if i could get some sort of velcro / tape with fake bullets or something to clamp it together

thankyou all again!

Well first off... those 'screws' are too long for that body, they shouldn't protrude through the plastic, try them in the rear of the body.

i thought the same. but the screws are direct swap from the original body.

the rear did not have any. the gearbox and battery go there.

when looking at the old body the 4 rear all all still in tact and do not join
