Anyone here into firearms?
 

Just wondering if anyone in this forum into firearms. I'm looking to build a AR15 and just wondering if anyone has a ar.:tup:

Semtex

And me, and at least a few others have popped up :)

Oh and in answer to your AR-15 question: you're barking up the wrong tree here. Go visit one of the most trafficked forums on the net: AR15.Com . Avoid the General Discussion area, with millions of accounts and being up for so many years, it's pretty much turned into an opinion cesspool. But over in the technical sections you can find pretty much any firearms info you'll ever need.

Edit: here's a link to the correct subforum for FAQs and posts and whatnot about building your own AR: http://www.ar15.com/forums/forum.html?b=3&f=4

I have a Les Baer Custom Police Special AR-15 with an EOTech 553 HOLOgraphic sight and Harris Bipod Model S-LM 9" to 13" with Leg Notch Swivel Mount Black . Total cost $2400.

Feel free to ask if you have any specific build questions you may need an answer to.

If you’re looking to “build” a gun from the ground up ARs are one of the few that can be the quintessential “drop-in” and “bolt together” gun... and even when they’re not there is generally very little fitting that has be done to a “MIL-SPEC” gun. In any configuration building an AR from the ground up will require a few special tools and sturdy bench vise. And with all that said, in many (most?) instances one may find they are better off to simply buy a complete gun and then modify it to their liking... but I also understand the pleasure and pride that comes from building stuff. ;)


And I will echo the comment above... AR15.com is a good place to go for information so long as one has a sturdy BS meter and is willing to wade through erroneous information to find the good stuff.

I built my AR-15...why not ask what you specifically want to know?

This forum might need a gun subforum soon :)

Random general advice: unless you're purpose-building a long-barrel varmint gun to shoot very light bullets at groundhogs and such, be sure to get a 1:7 twist barrel so you can stabilize the nice heavier offerings in 5.56 (like the 75gr Hornady TAP, and various Mk262 knockoffs like the ones from Black Hills).

I'm on that website. Just found it a couple of days ago. I've been on this forum for a while and I was just curious if anyone here was interested in firearms and wanted people from 370z forum opinions.
Now i'm not a gun crazy person but i enjoy going to the range even though cali are so loose with there gun laws here ;)

WOW speak english man LOL. I don't know what all that 1:7 twist barrel means lol.
I've been looking into different brands and trying to get familiar with it. So i may have a lot of questions. I've looked into maybe getting a complete upper rec from a company called POF usa. I hear they have really nice upper rec. I know that they are really expensive and you dont have to oil and lube certain parts of the gun which is nice to know. But from what people said in the ar15.com site they said the company is fairly new and they have proprietary parts and if the company goes belly up the ar would be no good if I needed a certain part for it. So that's a problem.
I also had a questions regarding a gas piston vs. the other version. I read that the gas piston is generally better but what do you guys think.
If i choose not to go with this brand what other good brands that uses the gas piston firing system.
I hear river rock and stag's are good brands. As for a lower rec, i was looking into spikes tactical. I like there design on the side of the rec. If you guys got pics of it show them.
What about POF vs. lwrc? I know they are both expensive. Thanks.

WOW expensive. Do you have any pics?

I went shooting yesterday for the first time in a LONG time. I was shooting an AR15 and found my accuracy hasn't changed no matter how little I practice... My grouping kind of still sucks, but at least I know I'm freaking lethal from 100 yards. :) I have 90% accuracy still.

Go me!!!


But I agree. Wrong forum. :D LOL

Was is built or did you buy it already put together? If built what brands do you have on it? Pics?

re twist rates and bullets:

Rifles are called rifles because the barrel has "rifling", which is a set of grooves (or something close to that) engraved in the inside of the barrel. These grooves twist, and their primary purpose is to impart a spin to the departing bullet to make it stable in flight. 1:7 is the ratio of the spin, and is the tightest spin generally available on a 5.56 cal AR-15. 1:9 is the common "compromise" twist rate, and you'll also see some 1:10 and even 1:12 guns. The tighter you make the twist rate, the heavier bullet your barrel can stabilize. The downside is that if the twist rate is too tight and you shoot very lightweight bullets, they could fly apart and fragment in the air from excess twist.

People who use an AR-15 to kill very small game (called "varmint" gun builds, because they're used to shoot small varmints like groundhogs and squirrels, etc) like to use very light bullets (40-55gr weight) at very high velocities, so for them a looser twist makes sense (1:10 or 1:12).

Standard issue US military ball ammo in 5.56 comes in 55gr (which will stabilize and be reliable in just about any twist rate) and 62gr (works fine in 1:7 and 1:9 barrels, but may not stabilize well in 1:10 or 1:12 barrels).

But according to modern ballistics research, the best performing rounds (on humans) in 5.56 tend to be the really heavy ones, like the 69gr, 75gr, 78gr, and yes even crazy 80gr rounds. 75gr Hornady TAP is very popular for a defensive round in the AR-15, for example. None of the heavier ones will stabilize in 1:9 reliably, only in 1:7. Some people have success with the 69 in a 1:9 barrel, but it's kindof a crapshoot depending on the barrel and bullet mfg.

Re the uppers you're looking at:

The POF upper you're describing is what's known as a piston-driven upper. Piston guns are a matter of a lot of contention and debate in the AR-15 community. The original design of the AR was to be gas-driven, whereas some other rifles like the AK-47 are piston driven.

Someone decided you could get the best of both worlds by modifying the AR design to be piston-driven too. Upsides are supposedly less recoil, and that the upper receiver and the bolt stay cleaner (less burnt stuff blowing on them all the time), but they still do require lubrication (don't let anyone tell you not to lube an AR just because it's a piston design, it still needs lube, the lube will just last longer). Downside is it's a relativelty recent and unproven serious design change to a good design that's proven itself well over the course of decades in the field. One of the biggest specific concerns is that the bolt is now driven back with an off-center force, which could cause galling of the upper receiver surface. Also has more small fragile parts than the original design, which may or may not fail early (not enough data).

LWRC also makes piston uppers, and are generally considered to be one of the highest quality piston uppers you can buy. If I were going piston, I'd shell out for LWRC instead of POF, but that's just me. Then again, a lot of people will tell you not to mess with a good thing, and just go with the original gas design, which is what you commonly find on all the major AR-15 variants (standard in Colt, Bushmaster, LMT, Knight's, Armalite, etc, etc).

It was built. It's not mine. I prefer not to own a gun, just know how to use 'em. I'm moving to the beach in a couple weeks, so I may buy a 1911. But aside from that, there's no need to have an assault rifle. A good hand gun is all you really need for house-hold protection. MAYBE a shotgun.
