So I just changed out the gas rings on my old Bushmaster. Is it really that easy?

I guess you will find out the first time you take it to the range :cool:
But yes, a lot of things aren't as hard as they look or as people make them out to be.

The trick I learned to see if you need to replace the rings is to extend the bolt and place it teeth-down on the table. If it stays extended they are still good.
No idea if this is correct though.

Remember to align the gas ring openings so they are spaced about 1/3 away from each other. Most drawing show them spaced that way. Some folks will insert the bolt with a jiggle motion to get the rings to cooperate on the insertion of the bolt iinto the carrier. A wide rubber band will also work to hold them in place as you gracefully insert the bolt into the carrier. I slightly press w/ finger nubs and jiggle. I don't think it really matters unless they were dry, or spread open some how or something like that.

I too use the Mc Farland on piece in the AR's i shoot most often, however, with three dozen hungry AR's to feed i do not have the one piece in all. I have never experienced a gas ring problem with either three ring or one piece in untold thousands of rounds and do not routinely chaange them or even count the number of rounds a given rifle has shot as there is no need.
