    100% agree with bobg. Shoulder must be done in a lathe if it's really tight but with 1/4 turn to go, not hand filing ( not precise enough). Thread is 3/4-20, ie one rotation 0.050", so 1/4 turn is...

    I have seen this carbine with the double rear sights before. Very easy to knock out the little "wafer" they slid into the dovetail. Then the standard rear sight can be mounted. Notch sight can be...

    Pistons were made from stainless steel (only part on the whole carbine), as to prevent any corrosion. If the nut or the inside of the piston chamber were to rust due to environmental factors, at...

    I bought my I-J in 1991 and still have it. A great shooter with no issues.

    Had a 20" barrel to keep it out of the Restricted classification, but replaced it with an 18 3/4" so it would look a bit...

    A most unfortunate failure, but is all to common with bolts. Cause of bolt failures are usually over pressure or excessive headspace or metal fatigue. The method of failure is the right lug cracking,...

    I was fortunate enough to acquire one of these STD PRO presentation carbines about 10 years ago, and still have it. It has no serial number, but the parts date it to near the end of production in...

    I've see this happen before, due to excessive headspace. In addition to the damage on the left side of your receiver, it might be bulged out here too. Can't tell from the pictures. It is basically...

    This appears to be the real deal. I usually need a carbine in my hands to appraise it, but of course, not practical in this case. I would give this an appraised value of $2500 - $3000 USD, in your...

    This serial number indicates June 1945 production at WRA. They were well into M2 production by then. Can I see a "2" overstamped on the "1" on the receiver ring photo?

    If you have a large bench vise (5" - 6"), you can take it off yourself. First, soak the area of the barrel where it's threaded into the receiver with penetrating oil. Patience required, I usually do...

    War Baby (p. 212) indicates interchangeability testing of 6 NPM's in the 4.23M S/N range in early March 1944. All had IBM barrels (p. 446). Probably a safe assumption that these were produced in Jan...

    Seems the myth about steel cast parts being substandard won't die. Casting technology has come a long way from the 1950's, and the 1970's (my I-J has mostly cast parts) to what is being produced...

    The key critical cast part on a commercial carbine is the receiver. Today, investment casting of a C4140 or C8620 steel M1 carbine receiver is just as good as a forged steel receiver. The concern...

    That (hack job) might be a clearance cut for the barrel clamp of the mounting bar for the IR sniperscope. In the right location. Military Manual for this mod indicated the area is to be "gouged".
