survivalshop Posted January 17, 2015 Report Posted January 17, 2015 Thanks for the update , good to hear it was an easy fix . I always make sure the Barrel Flange is seated up against the Upper Receiver , before I put any nut on . I have had a bunch of tight fitments with Barrel To Upper receiver fit, its the way I like them all to seat .
FaRKle! Posted January 18, 2015 Report Posted January 18, 2015 (edited) Wanted to post this so no one else makes this knuckle head mistake like I did. The knight upper receiver is very tight, the barrels do not go in easily even after heating the receiver with a heat gun. I had put the URX 3.1 rails on first and did not notice that the barrel had not seated all the way in and that was the problem all along. I took the rails off and could notice right away; once I fully seated the barrel correctly the BCG functioned perfectly. I am still taking it to a local gun smith and having it checked before I shoot it. Lesson learned. What kind of heat gun did you use? If it's not a hot enough one, sometimes a propane torch is necessary (such as with loc-tited gas blocks)... Don't be afraid to tap the barrel into the upper either after heating the receiver.

Lapp7660 Posted January 20, 2015 Report Posted January 20, 2015 I know this has probably been asked a million times but are there any other options for 308 uppers that are compatible to the Knight SR 25 lower ? Now that I am well on my way to completing my first build I was thinking of building another upper but of course finding a Knight stripped SR 25 upper is probably impossible and very expensive. Does anyone know of another upper that is compatible and not super expensive ?

Lapp7660 Posted January 21, 2015 Report Posted January 21, 2015 Thank you ! I knew there had to be a less expensive alternative. I ordered a Mega MATEN today for my next build
survivalshop Posted January 21, 2015 Report Posted January 21, 2015 Mega MATEN, Armalite AR-10A, and Genesis .308 stripped uppers are compatible with your SR-25 lower. Not sure the AR-10A would fit his lower Receiver correctly . <dontknow>
Lapp7660 Posted February 13, 2015 Report Posted February 13, 2015 I have an A2 Ar10 butt stock from Armalite and would like to know if it's safe to use an H3 Carbine buffer with it or will I have issues with the bolt hitting the lower to stop ?
edgecrusher Posted February 13, 2015 Report Posted February 13, 2015 No, that combo will not work! You will need a rifle buffer for that.

Search part #231-000-276WB (mfg part #308BS11).
Lapp7660 Posted January 6, 2017 Report Posted January 6, 2017 Anyone know what buffer tube, buffer, buffer spring, and collapsible stock I should get for my SR25 build ?

Which buffer tube, spring, and buffer you need will depend on which collapsible stock system you want. Whatcha got your eyeball on stock wise?
98Z5V Posted January 6, 2017 Report Posted January 6, 2017 I'd stick with Armalite parts. Most reliable carbine-stock option for these bigger ARs.
unforgiven Posted January 8, 2017 Report Posted January 8, 2017 ^^^^ What the bro sez..can't go wrong.
