Quoted: 1. What to use to clean them with? Both have a lot of oil and the SAR-2 has some cosmoline in/on the gas tube. I want them completely cleaned of all grease and oil and add my own. I think I read where someone suggested brake cleaner?
|
Everyone had their own ideas about what will work. I run a few patches throught the brake to get the major portion of it out, then use carburator cleaner. Brake cleaner would probably work just as well. Some guys put their rifle in the oven to bake it out!
2. Is it ok to use Shooters Choice or Hoppes to clean the barrel? I use SC to clean my M1 and non-chrome barreled AR. Will either of these hurt the chrome lined barrel? I know there is some issue with cleaners containing ammonia and chrome lined barrels.
|
Personally I use Hoppes, but I have never heard of any problems with any type of bore cleaner. I would use what ever I had on hand.
3. My .30 and .223 cal brushes should work, right?
|
You can use them, but sometimes I find the .30 cal. brushes too small. I use the .30/8mm combo brushes from Wal-Mart. The .30 cal. brush should work just fine though.
4. How do I take the lower handguard off without trashing it?
|
Take the cleaning rod off. Take the rifle apart. Take the gas tube off.
Looking down at the lower handguard from the top, in the front right corner on the inside of the handguard, there should be a small lever. Pry it upwards. Then slide the metal piece forward. You should be able to wiggle the handguard forward until it comes off. Once you do it once, it is easy.
Sorry for the book, but I like to take care of my rifles. These are in excellent shape and are good project guns. Thanks for the help.

No problem, glad to help. We all had the same questions at one time as well.
