cetme/hk/g3 question

[sava6e]

doing my first hk build and i have some questions regarding the fire control group,
i have downloaded the greenbook and armorers manual etc and when my parts kit came i started to disassemble everything so i could convert it to semi. and my trigger and stuff is completly different than the ones pictured online.
first off the hammer only has the semi notch on it, but yet it has what looks like an auto sear and also the trigger is different than the ones in the manuals. furthermore the housign which holds all the components has the same shape etc but has different holes cut out of the sides than the ones i have seen pictured. also doign a function test of it in the semi position works as it should , safety works as it should, however when on burst position it doesnt allow the hammer to lock back so which i am guessing is proper for the burst function. so Im looking for help as to why these might look different then the typical ones so i can make it compliant etc and only safe/semi functional. obviously i plan on welding in the block in the housing etc. would like help so i can star working on the rest of the rifle and get rid of the illegal parts thanx

I can't see the picture here at work but you might possibly have a cetme fire control group.

You have an unmodified CETME auto trigger pack.

Here are a few photos I have of a modded CETME semi pack off a buddy's gun. If you want to mod yours, you have some work to do! His was done by Century. We wanted to see if it would work in an HK lower- it did, sorta..

PS- the military CETME had no burst function- only auto.
