Break-in cleaning after each shot? How much?

I just read DPMS's instructions for AR-15 (non-chrome lined) barrel break-in. It requires cleaning the bore and chamber after each of the first 25 shots, then after each 10 shots up to 100 shots.

I'm so new to all this that I don't know if that means I have to do a complete field strip every time, or if there is a way to just pivot the receivers apart to do all this cleaning. (From reading on this board, I do know that I must clean the AR before even firing the first shot.)

Please give me a little advice on this. Fortunately, I can just walk out my front door and fire off a shot, then return to the house to clean whatever and however I need to. Sounds like I could be in for a lot of cleaning!

Thank you,
Brad

    You should be able to just open the reciever and clean that way... its what I did for breaking in my FAL, same basic design with the split reciever - upper and lower halves.

    they just mean clean the bore.
    I do not think it will help anything, though

    Break in rituals and cleaning procedures have adherents and detractors. Some consider it near holy and some say it is make believe. One thing for sure, if you do not do damage with cleaning solutions, jags and rods, it really cannot hurt.

    On a match rifle, ok I will do what they say, but on a GI style AR what are you going to accomplish

    I agree that it can't hurt, but I don't understand the science behind it.Way too many break in proceedures are out there. It would seem that if they had a positive effect, trial and error would distill the process down to one or two argeed upon ways to break in a new gun.

    A new barrel gets lapped as you are shooting, now matter whether you clean it or not. Steel surfaces in the bore have milliions of minute cracks and depressions of microscopic size when brand new. The lapping action of firing the first rounds through, seals and slicks over these surfaces.

    THE REASON FOR CLEANING AFTER EVERY ROUND FOR SO MANY SHOTS, FOLLOWED BY AFTER SEVERAL SHOTS, ETC., IS SO THE VOIDS WON'T BE FULL OF CARBON AND OTHER POWDER AND PROJECTILE RESIDUES AS THEY ARE SEALED. THE CLEANING ROUTINE MAKES FOR A SLICKER AND LESS LIKELY TO FOUL BORE SURFACE AFTER BROKEN IN.

    Add edit: The benefits of a proper break-in procedure are a reduction in friction for a cooler shooting bore which produces better accuracy and more consistent groupings, and dramatically extends barrel life.
