Hi guys my buddy gave me some magnus stinger buzzcuts but they are 100 grain and i shoot 125 grain off of a 2016 shaft my question is do you have any tips i can do to add that extra 25 grains so i can use these heads? THANKS!

wish I shot good enough that it would matter! lol.

What's the total arrow weight? Bow weight? Draw length? Try to get around 10GPP at peak weight minimum with your arrows. 50# peak weight = 500 grain arrow. 25gr difference isn't much. Screw-in adapters are the easiest option.

stick.  Try em as is. . . it might not matter at all.   Remember, once you add feathers to the equation,  you can "get away with" a ton more than when you are bare shafting.

or add weight either in front of or behind the (arrow) insert.  There are add on weights available commercially.

Try them and see how they work, 25 grains is not much difference for a well tuned trad set up.

If you'd rather have or decide you need the extra weight, the inserts for the PDP weights are available for 2016 and you can easily add another 25 grains of weight up front that way.

Try the Aftershock "the Booster". They are a 1/2" 25gr adapter that is screwed into the arrow, then attach the point. I bought mine at Gander Mountain, I also saw them at the bowhuntersuperstore.com, and e***.  Not trying to advertise, just giving you ideas where to look.

thanks

25 grains will not be noticed on a fletched arrow.

do it the elkherder way...toss'em on your nock,let'em rip and if they dont come flyin back at you you're good to go.  :D        :D

Chas I really like Gold tips brass weights, that screw into the back of the alum. insert. They come in 10,20& 50 gr's. You do need there long allen wrench. It is run in the nock end of the arrow to screw the weights into the insert. (That is already thread to accept them.)
    Most alum, inserts are not threaded all the way through. But that is nothing to fix with a 8-32 tap run though them. So the brass weights can be screwed into the back of the insert.
    Makes weight tuning real easy, and or to increase FOC JMHO
They look like this
 

Don't make work out of this.  Look at 3 rivers or Black Widow and buy some 5 grain brass washers.  Put 2-3 behind the head, screw'em in and your good to go.  You can easily add three which is equivalent to 15 grains.  That my friend is considered perfect in the trad world.
