TheД«arrels cracked lengthwise along the channels for the slide, between the receiver and gas piston housing, expelling gas into the stock area below the slide. During repeated firing, the barrels 'blew up'. With using stress proof steel when a number of employees went recreational shooting in the desert during a weekend. National Ordnance sold their M1 carbines with these barrels for a number of months. Testing the barrels after they had been machined. Alpine and Penney did not use National Ordnance, they stayed with the established resources companies Penney had used since the beginning of National Ordnance.ДЄrnold made the decision to change his source for barrels and made the mistake of purchasing barrel blanks made from stress proof steel, followed by the mistake of not extensively Number of significant changes at National Ordnance began to take place, not all of them good.Д«y 1965 National Ordnance no longer used Calgo Manufacturing, they machined the cast receiver and cast parts for the M1 carbine and 1903A3.

He acquired the machines and personnel, and by 1965 a Between 19 National Ordnance continued to use the resources already in place for casting, machining, and parts, as did Penney at Alpine carbines.ДЄrnold wanted to move all machining in house at National Ordnance, including the manufacture of his own barrels. The move and setting up for production took Arnold and National Ordnance only a number of months. Parts for both companies could be manufactured for both companies, from the tooling they owned jointly at Rimer Casting. They also agreed that the cast receivers and other cast There were a few exceptions, for distributors either man had becomeДЇriends with, such as Kaufman Surplus and Globe Firearms in New York City, whose owner (Manny Korn) was a close friend of Bob Penney. To the midwest, and they would both use their own distributors they already knew on the west coast. Whatever the case, National Ordnance certainly occupied this address for most, if not all, of the years John Arnold ran the business.ДЄrnold and Penney made an agreement that, generally, Arnold would market his National Ordnance M1 carbines to the east coast, Penney would market his Alpine M1 carbines It's possible this location was expanded in 1965, instead of newly built. Moved to this location when National Ordnance separated from Alpine in the Fall of 1962. The Los Angeles County Tax Assessor indicates the building at 9643 Alpaca St.

Arnold retained the National Ordnance name, all of the machinery, and moved to a small warehouse in South El Monte, CA. Refer to the web page devoted to Alpine's carbines. These were the only M1 carbines with the name Alpine. He continued production of the M1 carbine, under the Alpine name. Penney took the Alpine name, all of the personnel that had been National Ordnance, the M1 Garands, and moved to a different facility at 964 W Foothill Blvd in Azusa. In September/October 1962, before production of the 1903A3 rifles commenced, the differences between Arnold and Penney regarding the future of National Ordnance motivated Post WWII Commercially Manufactured M1 Carbines (U.S.A.)
