I want to switch out one of my RR fcg's to a burst. I know, I know, I can get the same thing with trigger control, but it's for my wife's 16, and she wants it. So i figure if i keep her happy, i can keep "playing" this sport. Plus it give me a project and honestly I want to play with it too.

My question is, can I use the auto disconnector with the double hook disconnector,  or do I have to get 2 new disconnectors?

If I'm correct I need a burst hammer, burst trigger, which is fatter, cam, cam spring and burst hammer spring, and 2 disconnector springs.

Is that all the new parts I will need? Or am I missing something?

Anyone want to trade a burst FCG for my auto? Or sell/trade?

Thanks for the help.

You need the following parts to convert a full auto configuration to burst:

1) Burst trigger
2) Left Disconnector
3) Right Disconnector
4) Disconnector Springs x2
5) Burst Hammer
6) Burst Hammer Spring
7) Burst Cam
8) Burst Cam Clutch Spring

Correction on 4) you will need a Regular Disconnector spring and a Burst Disconnector Spring.  They are somehow different.  Brownells used to have a nice diagram that showed all the individual parts

Are they different sizes, different weights or both?



 

Different colors but not sure if they are different in other aspects.

Edit to Add:
While installing a colt 4-way FCG, I was reading it that you had to be sure that you put the correct disconnector spring in the correct location.  On a side note, you better use KNS pins when you install the trigger section, that tapered point will make it 100 times easier to install.

Look over the the 4-way install that is sticky here in the M16 forum.  It has the steps that can be related to this discussion:
Steps 6 and 7 to me seems to be there is a difference
6 Burst Disconnector Spring (right, silver, burst specific)
7 Semi-Auto Disconnector Spring (left, black, burst specific))

Thanks for the link.  They appear to have the same number of coils.
