re: Official AR-15 thread

Is that a big fish tank?

Salt or Fresh?
Initial cost?
upkeep cost?
headache level?
worth it?

Its 374 gallons 96x30x30 acrylic fresh water SA/CA cichlids. I had salt for many years before Katrina...lots everything and didnt feel like doing salt anymore. I used to work in petsops so got things at cost...to expensive and too much PITA upkeep. This one I stick a mag 18 in and drain 1/2 and fill up from the garden hose. 3 fx5s running it.

Here is a long thread on the build of it...took a while going from my 240 that was on the stand before (had a mold issue). There are some pics and vids in that post and those vids are on my youtube page (slide fire vid above) along with a lot of other fish vids. I used to breed a bunch of different things.

As for price the tank was just under 3k I believe. Stand was 2500 (overpriced) because the cabinet people that did my kitchen built it. 300ea for the FX5s. 75 or so for each 30w LED flood light (4). Sand and wood was cheep...

374 build

Yep and Yep lol thanks.

It was stolen...all 65 cases of it

Just put my lower together, man that was way easier than i expected!

yup. ill tell people i put them togetehr and theyre like woah and im like dude it's easier than a lego set

I have been itching to build another one so bad, and my 300 is only 90% done (completed and sighted, just want a few other small things).

Alrighty fellas, need some input

starting to look for an upper, been looking at PSA and a few other places. Trying to keep it under $500. Don't know much about the differences between carbine, mid-length and all that. I guess just whatever one is cheaper, but I think i am leaning to mid-length simply for the lenght of the rail. Anything specific I need to look for? I've read on here that the M4 feed ramps are a must, anything else?

Length of rail has nothing to do with carbine, midlength, etc.

really? from what I understood, since the gas port taps off further down the barrel on the midlength the rail would be longer and the opposite for the carbine?

any specific brands to stay away from? I'll be putting it on a Spikes lower

Depending on what style of gas block you are using (specifically if you use a low profile one) any length rail can be used. If you have the traditional gas block that has the fixed sight on it, your options are somewhat limited. But there are manufacturers that make rails with an opening that allows the fixed sight to fit through the top, allowing a longer rail if so desired.

ETA: like this for example. Personally I'm partial to low profile gas blocks that fit nicely beneath the rails.

PSA has great deals and products. I bought PSA upper and lower from them. I almost bought a Spikes lower because it was a bit cheaper but it was sold out when I was ready. I went with PSA.

Our set up is very similar (mine is the FDE one above). The YHM rifle rail is heavy as hell.

To answer the question on the upper: Are you planning on building it yourself? Buying fully assembled? Do you plan on going with a fixed front sight?

Building an upper is not difficult, you just need to buy a few extra tools.
