The detent should stop it from falling out of place. Even if there is no upper attached it should always stay in the open or closed position. Do you hear the audible snap as the pin is pressed?

It's impossible for the rear take down pin to fall out. Tension from the detent and detent spring should keep it in place. If it isn't, then you need to make sure the detent and detent spring are actually in place. If they are, then check to see if the spring has enough tension (which is unlikely that it will be that worn). If for some reason it is, then just swap out the detent and detent spring with new ones. You can get them for about $2.

If you didn't put in any pins then the detent is the least of your problems... but it sounds like you only missed the detent spring/pin. Take your stock off, and make sure there is a detent in the hole in the back of the lower, then place the spring into the hole and replace the stock. The two parts you're looking for are a "rear takedown pin detent" and "rear takedown pin detent spring" or something along those lines. You should have extra parts left over from your LPK, but if you don't those two replacement parts are not expensive. Attention to detail friend, attention to detail!

I took it to the range and everything worked excellent, the boltcatch, stock, buffer and spring , ejector the only thing was that good dam takedown pin. im gonna ask something that might give you guys a heart attack but cant i just bolt the darn thing in with spacers , and where can i buy these replacment parts

Read my edit I gave you links to both items and proper assembly instructions. You could bolt it in place, but that would look stupid, and make cleaning a hassle. And it was your mistake so curse neither the pins nor the rifle. But mistakes happen, and thats an easy one to fix so don't stress out over it. Just spend $3 on a pin and a spring and wait a few days by the mailbox.

For now use a tight fitting 1/4 inch bolt

I have used aircraft bolts in place of the selector and the take down pins in the past with no problems.

With the 3/8 bolt I used in place of the selector I just ground the bolt in the same area that the slot is in the selector. I made it tight with Teflon flat washers and a lock nut.

I was just making that same joke about a different rifle with a coworker the other day. Reminds me of those old Reboks. Used to have to call time out during recess basketball games so we could "pump up our kicks" so we could jump higher. :p

You guys are laughing, but look at the OP's posting history. It's better than even money he hasn't installed a Prince50, bullet button or Madman grip.

We'll be reading about him in the papers soon.

I'm sure Vahehave has his rifle legally configured, he just missed a small step in assembling his lower. To be honest with you, I made a similar small mistake the other day assembling my new rifle, and it was far from my first time working on an AR. I actually got everything all put together and slapped the upper on the lower and racked the action open... and it was surprisingly easy. In my haste to see my pretty new rifle fully assembled I had left the recoil spring and buffer out of the stock. :o Everyone makes a few mistakes, at least he knew where to come to get a quick answer.

On a side note, I'll get around to posting pics/info/test target on my new build later tonight. :D

I don't mean to be a jerk but I can't help it on this one. I just like how instead of backspacing to delete "where can i put the part" he typed in "i mean buy them" right after it. Sorry, I just laughed really long about that and I actually thought of Borat as well hahaha.

Sorry I am a douche.

IIRC, you were in the Burbank/Pasadena area.

You may want to drop by or give Gunrunners (http://www.gunrunners.org/) a call. They had small parts a year ago when I was helping my bro build his first OLL. I picked up a spare mag catch assembly, but they seemed to have quite a few spare parts on hand from what I saw.

They are located in Duarte, right off the 210/605 interchange. Service seems to be hit or miss (http://www.calguns.net/calgunforum/showthread.php?t=27579) from what folks have said on the board, but they have a nice selection of eye candy when I was there last year and the OLL boom was just starting out. I had dealt with Paul and he was really helpful, YMMV.

WRONG.

Obviously you're not aware that there is a difference between the carbine forward assist and the rifle forward assist assemblies :p

I believe that rifles have shorter teeth on the forward assist pawl and heavier buffers.
Hence the need for additional pushes... :D
