guns

I'm looking into my first rifle and based on some discussions and reading it seems like the S&W Sport III may be a good starting point for a decent, prebuilt rifle without spending even more than I'd like.

These things are sold in various bundles and it's not always obvious to a noob when something is or isn't a good deal. For example, I've seen a bunch being sold with what are apparently "junk" optics - a Crimson Trace CTS-25 (google the battery life..). I've also spotted these bundles that seem pretty decent + there's a 10% promo code for S&W (SW10) firearms at the same store:

• Bundle 1 costs $855 in cart
• Bundle 2 cost $900 in cart

My questions are:

• are these actually decent deals, or have I just not looked long enough to know?
• for learning how to use an AR well, which sight makes more sense to a new shooter? I like the flexibility of the Sig Sauer Tango-MSR, but I'm looking for whatever will help me feel comfortable with a rifle sooner. FWIW I do plan on also getting backup flip up irons.

Any other notable things I should be looking out for? I'd plan on getting a soft bag for the range, probably some additional cleaning stuff, but tbh I'm still learning a lot in this space.
