very clean look!

Thanks for the link! They have some great prices on other parts I need. As for the handguard, I like the style (its not "overly tactical" imo) but it says its DPMS when I need an armalite barrel nut. :( Either way, I'll be ordering a few this and that things from them for sure!

Thanks wash! Appreciate the help. Just wanted to make sure given the matrix upper :) much appreciated. I can now continue pointing and clicking over the weekend for parts.

Sorry for yet another quick reply in this thread, but I found an interesting article that might address this: http://www.thebangswitch.com/everyone-makes-a-mistake-even-ruger/ In the article it mentions that they had to make a switch from magpul to DPMS magazines which caused the feel problem described. Does this imply that if you use the Armalite parts kits where applicable there is no need to modify the bolt catch if you use armalite or magpul magazines? I found a reasonably good deal on Armalite 5 round magazines (need them for legal purposes) so I may go that route if no mods to the bolt catch are required.

Oh and for those interested the ruger SR762 bot catch part number is in this PDF: http://ruger-docs.s3.amazonaws.com/_manuals/SR762-Insert-6287d1211f1cf939.pdf

Update: AIM surplus had a deal on an 18" barrel I couldn't refuse, so I got their BCG in the same pattern to hopefully avoid headspace issues. It was the 18" mid-length barrel. I have a couple of questions because after reading a bunch of threads on here I am once again confused. 1) What gas tube should I use with my matrix upper? From what I have read since the barrel is "DPMS" pattern I should get a DPMS tube 2) What length handguard would I need so that I can cover the gas tube for a cleaner look? I saw a 12" guard that I liked (very "no frills" look that gives more of a "rifle" look than a "tactical" look) that I was going to pair with a low profile adjustable block. Thanks for the help everyone! This is finally starting to come together on the parts front!

I did a quick google search and found a part number for the SR762 bolt catch. If they use the Matrix upper and lower it would make sense this part should just drop in, no? Either way for the price I got the set having to do one or two small things is hardly a deal breaker. From what I had read before going in on this its not as interchangeable as the AR in 5.56/.223. I kind of accepted I would make minor "mistakes" in purchase choices this first time around. There's always the chance to upgrade later. :)

My post was too old to edit, so I'll post here: I think Im going to go with either the coat hangar method or the tapped screw method like I just found in another thread. Also, if you choose to go with Chris's LPK instead of the Armalite one, his site shows the DPMS part kit but doesn't mention anything about modding it for the matrix lower. Do you have to mention that in the comments of your order or something? Thanks!

Chase - You may be right. It was a while ago so I don't recall 100%, but I could have sworn it was from Chris. Angel - Thank you for posting this. I was not aware of the bolt catch issue with the matrix lower. Is the armalite AR10A lpk the most "compatible" of the LPKs for this lower? Also, where is the best place to get a longer spring should one choose to go that route?

Sorry been away from a while, work has been hectic. That's where I got mine: gunbroker. I looked at it and if it is a blem I honestly don't see what it is (but I'm still an AR newb so YMMV). Right now AIM Surplus has an 18" barrel and bcg combination that can get me up and running on the cheap, but part of me may have one indulgence in the barrel (even though I don't need it) and go with a longer bull barrel. Once my work and home projects settle down (in the process of getting off the grid) I'll start posting pics of parts and starting the build in earnest.

Sorry for the late reply to this. Work and the home fronts have been challenging lately. Thanks for the replies everyone. And jonnyjet that's a sweet looking rifle! Thanks for posting! I have a few parts here and there that are on the way but things are in a state of flux due to work. I have to get in touch again and get a handguard from Chris. I expect the pace of this build to pick up in July once all the selected parts are here and time allows for assembly.

Robocop - I have to head out for the day, but when I get back I want to talk to you about that stock. Can you provide a link to the trigger group buy? I tried to get to the page but my browser had issues so I'm not sure I'm going to the right place.

That's a great price for a lower, but a family member already spoke to our FFL to order the upper/lower combination for me. That $185 I quote is for the upper and lower too :)

Thats what my research said, but I still want to give Chris a call because I want to order that handguard next while it is still on sale.

EDIT - I heard back from Chris via email, and I'll try and touch base with him during business hours.
