Hey guys. I've been lurking on this forum now for quite a while and finally started my first build. Kind of a plain jane build but enjoy the pics.......
RRA lower M&A LPK CAA grips, stock, carry handle Bushmaster upper receiver DTI 1/9 16" barrel No name flash hider F stamped FSB M&A BCG http://i673.photobucket.com/albums/vv94/bkirk87/ar15164.jpg http://i673.photobucket.com/albums/vv94/bkirk87/ar15165.jpg http://i673.photobucket.com/albums/vv94/bkirk87/ar15166.jpg http://i673.photobucket.com/albums/vv94/bkirk87/ar15167.jpg http://i673.photobucket.com/albums/vv94/bkirk87/ar15168.jpg http://i673.photobucket.com/albums/vv94/bkirk87/ar15169.jpg http://i673.photobucket.com/albums/vv94/bkirk87/ar15170.jpg I have a few questions for you guys also: 1. What is the bestmethod for pinning the front sight? 2. Any tutorials on assembling a bolt and carrier? 3. I still need to get handguards. I am looking at a FF tube with no rails. Any suggestions? Thanks for looking and i appreciate your help. |
| Not necessarily machine shop tools. I have a drill press if that counts. I am well aware of the possibility of ruining my barrel. But I think the benefit of being your own gunsmith far outweighs the risk. If this is something that is impossible to do myself then I will have no problem taking it to a gunsmith. Thanks again for your help. |
Yes, being your own gunsmith is neat. I like building my own stuff too. But this is a relatively minor step, compared to attaching the barrel extension and drilling the gas port. It's not as if you carved the receivers yourself. 
I just don't feel comfortable advising someone how to do this over the internet. |
haha I understand where you are coming from. You are right, but I want to do as much of this myself as I can. And from outward appearance, this does not appear to be an impossible task. No I am not milling my own receiver out of stock, but I feel I should learn how to do this, as it is a very critical step inproducing a fairly accurate rifle. I ordered my taper pins from PK tonight, so I guess I will jump head first into this when they arrive. Whether a success or failure, I will report the rusults. I appreciate your advice and look forward to further discussions as I dig myself deeper and deeper with my AR .

Am I missing something or don't most FSB usually have two pin-holes?
Where's your gas tube? Re: smooth free-float handguards: - VTAC / JP Enterprises https://www.jprifles.com/1.4.4_hg.php - Or, you could check out the offerings from YHM, about halfway down the page, and then another model a bit further down: http://yankeehillmachine.com/store/forearms.html Overall, I like the simplicity, clean functionality of the stock you chose. For a second there (before I saw the pic) I thought you were gonna go all tacticool/tapco/crap-magnet on the stock & accessories. Cool that you're attempting to build/piece together as much as you can. 
ETA: Don't forget to ensure your gas key is installed and staked properly. From a couple tacked-threads: Assemble your own LOWER, UPPER, FREE FLOAT, TRIGGER, GAS BLOCK - Step by step instructions! & Headspace, Torque values, and Barrel Break-in: Carrier Key Screws - 35 INCH pounds to 40 INCH pounds.

Thanks for your comments guys. I believe the front sight is new, therefore has no holes drilled for the taper pins. Sorry forgot to take a pic of the gas tube, but I do have it. I got a FF tube from RRA last night when I ordered my roll pins and such. Any experience with those? Seemed like pretty good quality at a decent price. I am trying to keep this build as simple and funcional as I can. That firs BCG you see in the pics is the assembled one that I bought from M&A. The other bolt, carrier, and gas key is supposedly a colt piece.....any ideas on how to tell? Thats is the one I eventualy want to asssemble and install in my rifle, having heard many times about the quality of Colt products. Thanks alot for your comment guys, they are greately appreciated.

Does it have a C stamped on it? And a bolt that has QC and MP markings? |

I know the carrier is marked with a "C" but I'm not sure about the bolt. I have the bplt, carrier, gas key, and a DPMS BCG parts kit. Anything else you think I will need?
Oh and the M&A LPK was a breeze to install and seems to function well. You will be very pleased. Thanks for your help guys. |

If you're going to go with a free float rail, then ditch the FSB and get a gas block. You'll save yourself some hassle.
It is possible to get the FSB aligned and installed using fairly rudimentary tools. I attached my barrel to its upper, then put the handguard cap and FSB on. Of course, my upper had a carry handle, so take this for what it's worth. Anyway, I aligned the FSB by turning the whole rig upside down and making sure the ears on the FSB and the ears on the upper were all touching on a flat surface. Once I was satisfied, I used C-clamps to make sure the FSB and upper wouldn't move. (Put something like a micro-fiber towel between the C-clamp and upper/FSB.) I then proceeded to drill my pin holes out using a 1/8" drill bit. I suppose roll pins would work fine here, but I used a 2/0 taper pin reamer to ream the holes. Then I installed the correct taper pins. Or you could have someone else do it. Or just go with a gas block. *Shrug* |
| Ya i thought about going with a gas block but I really like the look of the stock FSB. What is the problem with using a FF tube with the FSB? Sounds like a good idea with the reamer, any idea where I can get one? BTW I am using the stock taper pins for the FSB if that helps. Thanks for your help. |
