any help with Mrod trigger adjustment would be greatly appreciated.

If you like pictures my friend Jeff has a nice tutorial on removing the torsion spring ( is a gen 1 , they are for your purpose the same ) . The "First 100" Marauders came with "Match Trigger" the only difference - then - being said spring. You should be able to get a safe 6oz or so very easily.

the trigger part is right about half way down the page. Lot's of other documented exp. from a TOTAL airgun newbie back when he wrote it. Everything he has on the marauder ( and any other airgun ..... ) was his very first time seeing one so if you feel good about it you should be able to DIY "tune" rebuild etc.. you rig.


Keep us posted,

Bay,
Your most welcome. Personally I like pictures better than video's, just old I guess.

On the "1st 100 Marauders" ever sold - and just a few extra- they were pre-sale ( order ahead of release ) and came with a "match" trigger. That trigger did NOT have the torsion spring , after the "1st 100" they added the extra spring so it could not be adjusted as light as many airgun folks like. I'm not certain these days ( but most laws seem worse now if anything ) but on firearms a trigger must be above 2.5lb ( ??? ) UNLESS it is a "match" rifle and some folks felt it would only have been done due to lawyers advice, I think they did the right thing as many are not used to a 4oz trigger.
The trigger on the Marauder ( gen 1, gen 2 is still very very close) is more or less a mirror image of the old theoben MFR target rifle which is a fine rig indeed and as the patient was expired. Pretty sure the RAW trigger blade still fits the crosman unit ( some like it better on Gen as it sets back further) .

Personally "I" most stay away from the rear most screw which adjusts angle - gosh it interacts with the 1st & 2nd stage 27 different ways it seems- just remove extra spring & carefully adjust 1st & second stage, cock it, slam the butt on the ground & if safe go fire another 500 pellets, then, maybe, a polish or shim if you are a true triiger snob.
