Guest LLArms Posted May 18, 2012 Report Share Posted May 18, 2012 I'm seriously considering swapping out the Magpul PRS on the Titan to a Magpul STR.Ive been trying to justify it, but the cheek riser on the PRS was just not designed in the proper place IMO. Its to far back and I think its causing some problems in my form.So I'm assuming I need the correct buffer tube assembly, do I also need to replace the buffer and spring?

edgecrusher Posted May 18, 2012 Report Share Posted May 18, 2012 yes, the carbine collapsable stock uses a different tube,spring,and buffer Quote Link to comment Share on other sites More sharing options...
Robocop1051 Posted May 18, 2012 Report Share Posted May 18, 2012 Short answer... Yes.Also take a look at the RRA Operator A2 stock. Quote Link to comment Share on other sites More sharing options...
mrraley Posted May 18, 2012 Report Share Posted May 18, 2012 I'm not to framilar with the Titan as to what buffer and buffer spring they are useing. But in the ArmaLite rifles they have their own receiver extension tube for the AR-10 that is longer than the one for the M-15. Quote Link to comment Share on other sites More sharing options...
Guest LLArms Posted May 18, 2012 Report Share Posted May 18, 2012 The Titan is our rifle, its basically a DPMS LR-308 in transformer gear. <laughs>So from what I gather online I need the following:Collapsible Buffer TubeAR-15 Locking NutNew SpringNew Buffer???If I am completely wrong can someone give me a detailed list to do the swap over.

mrraley Posted May 18, 2012 Report Share Posted May 18, 2012 I am not to framiliar with the DPMS parts on their .308...But ArmaLites AR-10 carbine receiver extension tube is 7 5/8" on the inside depth and only have one spring for the rifle and carbines. The parts you will need are:Carbine receiver extension tube,Locking ring (castle nut),Locking plate,Buffer,Buffer spring. Quote Link to comment Share on other sites More sharing options...
Guest LLArms Posted May 18, 2012 Report Share Posted May 18, 2012 Well I'm going to go make a FS/FT thread, but if anyone has been looking out for a good deal on a LNIB Magpul PRS in black I've got one available. <thumbsup> ;Dhttp://308ar.com/forum/for-sale-or-trade/fsft-lnib-ar-10-magpul-prs-%28black%29/ Quote Link to comment Share on other sites More sharing options...
survivalshop Posted May 18, 2012 Report Share Posted May 18, 2012 You may want to think about if you want a Mil spec or commercial collapsible stock / receiver extension .No matter what you hear about the two , one thing is certain & that's the commercial receiver extension tube is thicker ,same inside dia , but the tube is thicker & makes the outside dia larger than the Mil spec. It is why I used commercial on my 308 . Quote Link to comment Share on other sites More sharing options...
Guest LLArms Posted May 18, 2012 Report Share Posted May 18, 2012 Yes I will be going with a com spec. :) Quote Link to comment Share on other sites More sharing options...
Retired JM Posted May 19, 2012 Report Share Posted May 19, 2012 In addition to the receiver extension and castle nut, you'll also need the receiver plate that goes underneath the nut. Quote Link to comment Share on other sites More sharing options...
Robocop1051 Posted May 19, 2012 Report Share Posted May 19, 2012 Honestly, I think you should look at other full stock options instead of the collapsible stocks. Wouldn't a compact stock defeat the purpose of your rifle?The RRA A2 Operator stock and the VLTOR A2 ModStock both will fit your current hardware, and only cost about $100-$150. They come with cheek rest storage areas on both sides, and they still line up like a standard stock. I think it'd be nice to see an aluminum or steel dowel lathed out to insert inside the storage area for the extra weight in the rear. Just my $0.02, it usually ain't worth much more than that.

Guest LLArms Posted May 19, 2012 Report Share Posted May 19, 2012 Fixed or collapsible doesn't effect the the project. If anything it will be a benefit to move to collapsible for storage reasons.Plus that is what testing is for.At least this way I have both types of tubes on hand and moving forward I can test either type of stock without needing extra parts.Nothing is ever written in stone.

imschur Posted May 19, 2012 Report Share Posted May 19, 2012 Have you tried an A2 with an Adjustable Butt Plate? Seems like a "Good fit" to me. Quote Link to comment Share on other sites More sharing options...
Guest LLArms Posted May 19, 2012 Report Share Posted May 19, 2012 To be perfectly honest the A2 is butt ugly to me.Project Titan is not only based in performance, but a work of art to me.I have an extra A2 butt stock for sale if anyone is interested. <laughs> Quote Link to comment Share on other sites More sharing options...

Guest LLArms Posted May 19, 2012 Report Share Posted May 19, 2012 Maybe I just need to design my own butt stock. :o <lmao> Quote Link to comment Share on other sites More sharing options...
