Jetdoc Posted January 21, 2017 Report Share Posted January 21, 2017 Gents, Ive built AR 15s before and am researching for my first 308 build. Can someone explain the difference between a SR and DPMS build? I know I'm in a money pit hobby and dont mind it. What I hope to do is spend wisely. If I understand from my reading the barrel and BCG have to match a SR or DPMS configuration? This is my first question of many to follow.

AnOldBiker Posted January 21, 2017 Report Share Posted January 21, 2017 I ended with the DPMS due to two main reason, 'parts supply' and 'cost'. With the AR10, you're stuck mainly with Armalite supplier only and the cost was higher. With the DPMS, parts are developed and sold by more after market suppliers, quality material and the cost is less. There are many videos and write-ups of this on the web from people jumping into the early in the game. Quote Link to comment Share on other sites More sharing options...
Jetdoc Posted January 21, 2017 Author Report Share Posted January 21, 2017 Thanks Gents.. If I understand correctly I want to keep the Barrel , BCG and Buffer all the same spec, either SR or DPMS? As for the upper and lower receiver group should be from the same manufacture , Aero Percision, DPMS, Spikes, ect ? Quote Link to comment Share on other sites More sharing options...
edgecrusher Posted January 21, 2017 Report Share Posted January 21, 2017 I think you're very confused, sr is not a type but Knights Armaments brand name. It is typically dpms based or armalite based. Look at the forum a bit, there is a metric shit ton of info Quote Link to comment Share on other sites More sharing options...
blue109 Posted January 21, 2017 Report Share Posted January 21, 2017 SR25 is a specific rifle. The main patterns are DPMS or Armalite AR10. It gets confusing because even manufacturers sometimes incorrectly refer to their parts as AR10. several of the big manufacturers like Larue and RRA are completely proprietary and don't use many off-the-shelf parts. Some are semi compatible with some proprietary and some generic parts. I'd suggest you find a reciever set you want and start researching the build from there.

edgecrusher Posted January 21, 2017 Report Share Posted January 21, 2017 My obr is actually armalite compatible... just be confusing Quote Link to comment Share on other sites More sharing options...
Jetdoc Posted January 22, 2017 Author Report Share Posted January 22, 2017 Thanks Guys .....I did find a matched receiver set today. That's it for parts until I do some more research and ask many questions. Quote Link to comment Share on other sites More sharing options...

xTRUCKASAURUSx Posted August 5, 2018 Report Share Posted August 5, 2018 I know this is over a year ago, but I’m looking at the Jack10, trying to figure out what building one will cost me. Are uppers from other companies interchangeable into this platform? (Example an Aero Precision .308 complete upper, or the Uintah 6.5 creedmoor bolt action upper) thanks for any info!

Robocop1051 Posted August 6, 2018 Report Share Posted August 6, 2018 The Jack10 looks like an Armalite pattern, but it could be proprietary. It is definitely not AeroPrecision compatible. Quote Link to comment Share on other sites More sharing options...
xTRUCKASAURUSx Posted August 6, 2018 Report Share Posted August 6, 2018 (edited) This is the thing that worries me. I’ve contacted Spike’s via email and Facebook, but no reply yet (of course it’s the weekend lol) i havent been able to find them seperated, so I’m guessing they’re proprietary.. which makes me sad. Because I can’t put this guy on there...: https://uintahprecision.com/product/bolt-action-ar-upper-assembly/ Edited August 6, 2018 by xTRUCKASAURUSx Quote Link to comment Share on other sites More sharing options...
98Z5V Posted August 6, 2018 Report Share Posted August 6, 2018 ^^^ It's funny how many times they use "AR-10" in their description, and there's NOTHING about that upper receiver that would work right on an AR-10... Terminology is important. Very important. That manufacturer doesn't know what the hell they're talking about... In light of that - think about what you'll buy from them.

The Jack10 is only sold as a set. 2. That bolt-action upper will NOT fit a Jack10 lower. Here’s a close up of the bolt action upper vs a Jack10 receiver set. You’ll see the lines just don’t match up.

PS. 98 is absolutely right here. If a company doesn’t know wtf they’re making/selling... STAY AWAY!!! That upper will NOT fit on an AR-10.

xTRUCKASAURUSx Posted August 6, 2018 Report Share Posted August 6, 2018 Thanks for all the help, everyone. Looks like I’ll be piecing together a 6.5mm creedmoor upper myself. I also got confirmation from Sharps bros. that they are, in fact, a machined set, and not interchangeable with any other uppers... a shame. Back to the drawing board!
