Your recent editing history at AR-15 style rifle shows that you are currently engaged in an edit war. To resolve the content dispute, please do not revert or change the edits of others when you are reverted. Instead of reverting, please use the article's talk page to work toward making a version that represents consensus among editors. The best practice at this stage is to discuss, not edit-war. See BRD for how this is done. If discussions reach an impasse, you can then post a request for help at a relevant noticeboard or seek dispute resolution. In some cases, you may wish to request temporary page protection.
Being involved in an edit war can result in your being blocked from editing—especially, as the page in question is currently under restrictions from the Arbitration Committee, if you violate the one-revert rule, which states that an editor must not perform more than one revert on a single page with active Arbitration Committee restrictions within a 24-hour period. Undoing another editor's work—whether in whole or in part, whether involving the same or different material each time—counts as a revert. Also keep in mind that while violating the one-revert rule often leads to a block, you can still be blocked for edit warring—even if you don't violate the one-revert rule—should your behavior indicate that you intend to continue reverting repeatedly.
