Thinking of getting a 300AAC Blackout need some info

I have been looking for an upper for one of my lowers in 300aac Blackout. I found one for a good price and was wondering if anybody has any experience with the company dsarms? I can get an upper minus the bolt, bolt carrier, and charging handle for $335 plus shipping. The bolt group is 115 for chrome, and the charging handle with big latch is 45 so $495 for the whole shebang. They have a little notice to call for dealer pricing. So if any of you dealers would like to order this for me and can save me a couple of dollars and make some yourselves feel free to pm me. Also if any of you dealers can get me a complete upper with big latch for $500 from a reliable company feel free to pm me. Next thing I could use is a Bushnell holosight like this one http://www.opticsale.com/bushnell-1x-matte-holosight-510023-2198-prd1.html can anybody beat or meet that price on here? also anybody know what a type N 1.5 volt battery is. Is that the same as a lithium CR123? I could get 2 of those for the price of 1 eotech and yes I need 2 of them.

Just work 5 days instead on 2 for the next two weeks and buy two if them.
Really though wish I could help. Maybe try Mr.Clean. Or maybe Dock Rocker.

a type n battery is not the same as a cr123. type n are the same diameter as the ones in the cheap laser pointers( those are lr44) but the n is about 3/8" or so thick

If they have the Bushnell Halo sight in stock for that price, buy it. Nobody else has them, that I can find. Bushnell stop offering them a couple of years ago.

Well guess I'll buy them

I still need info on dsarms. Anybody?

Sigma haha. I don't like to work 5 days in a month no way I'm gonna do it in 2 weeks. I went to work both mondays in this month so far looks like a trend starting here. Got to work this coming up monday too.

Well Opticssale.com was a crapper. They didn't have any in the wharehouse they just haven't taken them down off the site yet. They tried the ole bait and switch on me too. sent me an email with an additional 10% off of a comparable in stock optic, which just happened to be the only one they had was a $700 eotech. So needless to say it was a no deal for me.

I don't have any experience with the DSA uppers, other than seeing a few and reading about them. Like anything else, some like them, some don't. Their regular uppers are usually 275 minus the bcg and ch.
