buschy,
Break in on the AR is a bit different than with bolt rifles.
With Bolt rifles, the focus is on the bore.
With the AR it is on the action, and on the bore, but with a twist.
The bore is chromed.
Chrome bores have thier own rules.
Punch/scrub the bore clean, and dry.
Scrub the action to clean.
Apply lube to the action.
Run at LEAST 200 rounds without cleaning.
If needed, apply lube to the action.
The chrome in the bore needs to be slapped around a bit to break in/take a polish.
The action as manufactured, is TIGHT, and the parts and pieces are getting to know each other intimately.
200 rounds is a general rule.
Some take more, some less.
500 rounds is my personal Standard.
The thing will burp, fart, hiccup, and not run untill you get it broken in.
Once broken in, and then cleaned up, they just flat RUN!!!!!!!!!!
The bolt rifle rule, of one shot and clean, does NOT apply!!!!
Go Chrome, or go HOME!!!!!!!!!
In short.
Take it out of the box.
Clean it spotless.
Lube the action.
Load the estate wagon with ammo untill the springs sag.
Head to the range.
Shoot untill it hurts, adding lube to the action if needed.
Leave the bore dirty untill ya hit 200 rounds or more.
At 500 rounds, scrub the crap out of the thng, lube it up, and just run the thing!
As a die hard Bolt rifle geek, the process is contrary, but proven.
Chrome bores should be a LAW!!!!!!!!!!!
