My Noveske lower I so lovingly put together with a stag arms LPK has one (or two) problems. The damn pins for the trigger, and hammer keep migrating out to either side. They have not come all the way out, as in fell on the ground, but they have come about an 1/8th of an inch out to either side. Was there somthing i missed in the assembly of my lower?
any way to keep the damn pins from coming out?

Re: any way to keep the damn pins from coming out?
The hammer and sear springs are supposed to fit into notches in the pins to prevent them from walking out.That said, it still can happen.Knight's armament i believe makes special pins that have "E" clips on the end that completely stops this bullshit.

Re: any way to keep the damn pins from coming out?
There should be two grooves in each of the pins. One groove in the center, and one to the outside. Both pins should be the same. On the trigger pivot pin, the outer groove is used to retain the pin. The legs of the hammer spring should rest on the trigger pivot pin. One of the legs should sit in the outer groove on that pin. Make sure that leg of the spring is sitting down between the receiver and the trigger, not on top of the trigger itself. It needs to sit on the pin. The pin can be installed in either direction...it doesn't matter which leg of the hammer spring sits in the groove, just that one does. This should retain the trigger pin. The hammer assembly should have a small c-clip or retaining spring in the center of the pin bore. This should catch on the center groove of the hammer pivot pin. You can check this to see if it's there by removing the hammer and inserting the pin in the hammer pivot bore. It should snap into place when it's centered in the hammer. If it doesn't, and it seems like it's free floating,the hammer is missing the little retaining clip. You should also be able to look through the hole in the hammer and see the little clip hanging in the bore.

Re: any way to keep the damn pins from coming out?
thank you all i might look into those pins a little more. upon further inspection i did not have the springs in the little grooves like they should have been

did you install them properly ?
in my 40+ years of AR-15 ownership, i have NEVER had a pin "walk out" from factory assembled or my own builds.

Re: any way to keep the damn pins from coming out?
well pete i used a picture illustrated manual from ARF.com worked pretty good, but did not point out about the springs in the grooves. thats why i posted here asking for help rather than back on ARF, because i knew people would know

Re: any way to keep the damn pins from coming out?
This was a problem on some early M16a1's, the trigger an hammer pins were being rotated when the fire control parts, were moving. Problem was some pins were undercut for the spring legs to lock in properly, and some larger than spec, spring wire, was being used. The combo of all three will not allow the pins to stay in at all.
Fix is, replace pins an springs with spec parts, an lube the pin an trigger as well as the hammer areas where they make contact, problem solved.
