AR-15 build info.

Troy sights for BUIS. Not aware of anyone making pinned uppers with Troy MD's. Having a non pinned 14.5 and not owning a lower that would legally accept is not a good idea. Especially if you have a lower that could accept it that isn't legal.

thanks for the heads up.

Are BUIS designated for just one caliber? i.e. can ar iron sights be used with a 9mm ar build?

No they are designed to sight the right - caliber is irrelevant.

However I'd point out most of the sights with elevation adjustments (chopped carry handles/LMT, KAC 600m, etc) are designed for use with M855 the range values are caliber/load specific though they can be useful for other calibers/loads with similar trajectories.

In any even they can be used with any caliber including 9mm, it's just the range values won't be correct.

If people want to build the AR themselves, how can they go though all those background checks and get the license? Thanks!

Use an FFL to buy your stripped lower and that's it build away

so get FFL is the first step, then can purchase the parts. am I right? thanks.

You only need an FFL for the LOWER.

The rest of the gun, you order to your casa.

You can buy everything you want right now, you just need to go to an FFL (or gun store) sign paperwork .. wait 7 days and pick up the stripped lower.

Your lower is the only part that has to go through the paperwork, this is the part that has to go through an FFL, just like a handgun. Once you purchase your lower, you can buy all of the other parts online or at a gun show or from your local gun shop.

Sorry for too many stupid questions. I am new here and still learning. I don't have any firearms now. I mean can I get FFL first without buying any firearm now. can I buy any kinds of firearm like handgun or AR once I have FFL?

You go to an FFL ( lets say a store) to buy a handgun or a stripper AR low. You go to an FFL every time you buy a handgun or stripped lower and fill out the paperwork every time and have a background check done every time for each regulated firearm.

 

[Stevie Boy]

An FFL is a "Federal Firearms License" typically held by a gun shop (owner) who is authorized to trade/sell firearms. As a purchaser, you must use an FFL (find a local gun shop willing to work with you) to buy the lower for the AR you want to build. Unless you are going into the business, you would not be getting an FFL of your own.

 

[huesmann]

Note that you will want to have your training certification (mdgunsafety.com) before you go to your FFL dealer for your paperwork, because they will need your number.

or your DD-214 (If you're former military).

 

[tsmith1499]

The lower is the only part of the firearm that has the serial number on it. Even if it is stripped. That's why you have to get it through an FFL.

AR-15 Newbi

I will have my first AR-15 this Wednesday 5-9-12, it is an Olympic AR with stainless barrel, no sites, scopes, stripped basic, I would like to hear from the AR-15 veterens out there what the think I should equip it with, I really like the tactical gear though after reading several threads and lots of reading, there is so much that can be done with an AR so I am very excited about making this weapon my own, so anyone out there that could give me some pointers and advise I sure would appriciate it.

depends on your budget an what you plan on doing with it. I would probably get a free float rail that way you can mount a grip/ bipod/light/back up sight....

Flash Hider Help

I have one of the standard A2 style flashhiders.

I cannot get the "non vented" side to face downwards. It is always facing up. I have a pinned gas block and with the appropriate blocks in the vise, it will almost be physically impossible to torque the hider enough to get it 180 degrees.

Any thoughts?
