Rack, Regardless, you have a nice collection! Congratulations!

Welcome to the forum and congrats on your purchase. It is hard to tell by your pictures/description but it sounds like you are just missing the bayonet lug. There is currently one for sale on gun broker or maybe Joseph Scott has one. Also, you say the bolt is matching? As far as I know, no Johnson left the factory with matching numbers. Since your rifle doesn't have a prefix, the records are available for every part your rifle had when it left the factory. Wayne

Hey Alasdair, I just had a guy in Texas repark a M1 carbine. His name is Tim Strait and his company is Warbird Customs. Internet by the same name. Great guy and beautiful work. Prices extremely reasonable. Wayne

Since I purchased my JSAR, I have only had the opportunity to take her to the the range twice. As with all of my older rifles I sight them in at 100 yards. After that I rarely shoot at any distance less than 200 yards. The first time I took my JSAR out, it took me nearly 50 rounds just to get it sighted in at 100 yards! Frustrated and out of ammo, I called it a day. A couple of days ago, I gave it another try. For about the first 20 rounds, I was shooting 2 inch groups at 200 yards on steel plates. After the first 20, the groups started getting larger and larger until I wasn't hitting the plates at all. Again, at 50 rounds, I called it a day. My question is has anybody else experienced accuracy issues as the barrel heats up? I'm shooting 150 g JHPBT. These are the same rounds I run through a Garand, 03, 03A3 and 1917 without a single issue. Any help would be greatly appreciated! Wayne

With the help/advice from the above members, it appears my accuracy issues have been resolved. Upon inspecting the barrel, I determined the MW = .5! Crown is in excellent condition. Since it appeared the mounting screws where coming loose every time I fired the weapon, I removed the screws and found all of the star washers where flat. One of the mounts was missing the flat washer so the star washer was just burying itself into the wood. Joe supplied me with the correct flat and star washers. After reassembly, it was time for another range visit. Rifle sighted in at 100 yards in 10 rounds. First shot at 200 yards on a 1' square steel plate was dead center! Any variation from dead center for the remaining 40 rounds was strictly me (still getting used to its 2 lbs trigger pull) and my old eyes. After 50 rounds, all mounting screws still tight! I want to thank everybody for your advice and expertise! I very much appreciate the help! Wayne

Neil, sent you a PM

Hey Neil, Welcome! Remove the stock from the receiver. Remove the large head screw under the safety and the second large head screw just behind the magazine. The trigger group/block slides out the top. When you remove the screws, don't loose the washers underneath. Wayne

Hey Joe, Sent you a PM.

Ed, Sounds good. I will will take it out again to determine. Joe, I thought about the sights and checked them for tightness while I was cleaning this morning. They appear to be tight. The screws are a different story. When I first purchased the rifle, I inspected it but don't recall checking the screws. After my first range visit, I checked the screws and they were all very loose so I tightened them up. I just checked the screws again and they are loose again? Not as much as before but noticeably loose?

Hey Ed, I am not a fast shooter. I'll load 5 rounds and it probably takes me 3-4 minutes to go through the five. Then I'll look through my sighting scope for a rew minutes, pick up my brass and then start the whole process over again. I agree with the amount of ammo it took to sight in at 100. But when I took it out again, I was able to hit 200 yard steel without issue for the first 20 or so rounds?

Good Morning Art, that is exactly the input I was looking for! I have not gauged the muzzle and throat as of yet. I have a gauge ordered. The barrel is bright and shiny without signs of pitting. First shots are fairly accurate then open up as barrel heats up. I really appreciate the help!

Hey Greg, Even if these where original Johnson barrels, which clearly they are not, my biggest fear is the statement in both auctions "sold as is". Anytime a seller on gun broker doesn't allow me some kind of inspection period, I stay away from. Wayne

That's very nice! I'd be very proud of it also

Do you have any pictures of your restored JSAR?

Pictures?

I saw that also. Unbelievable! The most I have ever seen one go for was about $350. Makes me glad when I purchased my JSAR, a bayonet and scabbard came with it!

I am sure this has already been covered but I can't find any related posts. My JSAR magazine only accepts 8 rounds. Is there a reason and if so can I rectify? Thanks Wayne

Problem solved! Exactly as Joe said! The magazine door spring was installed upside down. Thanks again!

Thanks Joe! As always, appreciate the help!

Did a 604 build a few years ago. I have numerous AR parts but none of them are original Colt or very old.

I recently found an original instruction manual for the JSAR. In pretty good shape but not a copy or reprint. I have never seen one before and was wondering what would be a good price to purchase? Thanks Wayne

Sorry about that Greg! I read your post wrong. For whatever reason I thought you where talking about the bolt catch

Greg, My JSAR does not have a bolt stop. From what I understand, the early models did not have them. Mine is one of them and I fire it often without issue. My only concern is I don't like firing any weapon dry so I have to remember how many rounds I have fired because the bolt does not lock open after the last round. Wayne

Hello Greg, Contact Joe Scott on this forum. He will have all the parts you should need. Wayne
