I have a bushmaster flattop with a 16 and shoot mostly xm193.  Just recently i have been having a problem I shoot righ handed and no matter what position i am in after the gun fires i get burnt powder blowing back into my right eye.  Any help would be great

The options are,
To install a heaver buffer to slow down the unlock (may help a little if the rifle is over- functioning with the hotter ammo),

Go with a gas buster charging handle to prevent the gases from making there way out through the charging handle/upper open area,

Or to break out the RV sealant and make a gas buster charging handle of your own.

P.S. You are wearing shooting glasses at least, and the problem is the gases making their way past the glasses?

Also, Welcome to the site!!!

heavier buffer will help.  If you add a JP adjustable gas block or MGI adjustable gas tube you can tune it to run with zero blowback.
