Are Howa 1500 Any Good

Jan 07, 2002 The affected rifles bear serial numbers from one of the following series on the receiver: PN00010 through PN87159, LS00001 through LS05150, M000001 through M020422, LS10001 through LS10309, B000001 through B028450. The safety upgrade will replace the bolt sleeve to prevent misassembly of the bolt, which might occur on the affected rifles. Mar 07, 2017 No pictures online or anything. The thing that is throwing me off is the coloration of the wood stock and how the wood stock runs all the way to the end of the barrel. I was wondering if maybe someone put an after market stock on it or not. I also have a 50's 60's FN.243 Win I cant seem to pin a date on with the serial #. Heavy barrel in.223 is a very good shooter. Hack mac keychain free. Howa has a recall on older actions by serial number about owners putting bolt together wrong. Might want to check your serial number against their list. Factory barrels are good. Trigger better than some. Any good stable stock. The recall does not apply to any other model of Howa M1500 rifles. In order to determine if your rifle is affected by this recall, please check the serial number on your rifle and refer to the Serial Number List located at www.regcen.com m1500ss, or call the Howa Registration Center toll free at 1800 688 947.

The Caliber .30 AOA Howa Autoloading Rifle Model 300

The Model 300 is a sporterized hunting version of the .30 caliber M1 carbine manufactured by Howa.

In 1961 the American commercial M1 carbine manufacturer, National Ordnance, was owned by Robert E. Penney Jr. His partner, John Arnold, owned Alpine Sales, the sole distributor for National Ordnance. In 1961 John Arnold returned from Japan with a Howa Model 300 for evaluation with the intent of possibly importing the rifle.

National Ordnance considered importing the carbine from Howa in Japan.

Penney and Arnold decided the Howa Model 300 was too expensive to import. Arnold went on to own National Ordnance in 1962 and died in 1973. The Model 300 rifle Arnold brought back with him was sold to a buyer somewhere in the United States, after his death.

A brochure for the Howa Model 300 was mailed to Kleins in Chicago from Nagoya Gun Services of Nagoya, Japan in July 1964. Nagoya Gun Services was the sole distributor for Howa. The date 13 Apr 1964 was handwritten on the cover. Handwritten on the inside was a personal note to Kleins requesting a catalog and export price list. Kleins was a major gun business with multiple retail locations in the Chicago area. They decided not to import the Model 300.

The Howa Model 300 shown in detail further below was acquired for evaluation by Ithaca Gun Company in Ithaca, NY. It's clear Howa and/or their distributor attempted to locate a U.S. company in the early 1960's for sales of the Model 300 in the United States. At the time at least four companies were manufacturing commercial carbines in the United States. Surplus carbines made during WWII were released for civilian sales by the government in the early 1960's. After adding up the costs involved in purchasing, shipment, and importation the U.S. companies believed their profit margin would be far less than selling U.S. based carbines and/or the retail price of the Howa Model 300 would be too high and would not sell.

In War Baby Comes Home by Larry Ruth, pp. 729-732, Ruth discusses the Howa Model 300. After making an inquiry to Howa about their carbines, Ruth received a copy of the Howa Model 300 brochure, in addition to information that Howa had manufactured approximately 10,000 Model 300 M1 carbines.

Howa manufactured rifles and shotguns for Smith & Wesson for several years in the early 1980's. When Smith & Wesson discontinued the weapons, Howa manufactured them for Mossberg, then Interstate Arms. The rifles and shotguns had the Howa name and 'Made in Japan', along with the name of the American company and their model number. Howa now manufactures the Model 1500 under the Howa name. The rifle is imported by Legacy Sports of Reno, NV. Ruth indicated the Ithaca markings on the Howa Model 300 M1 carbine were not consistent with an importer's mark. They were more consistent with Ithaca having put their name on a Howa manufactured rifle.

A Later Version of the Howa Model 300

Carbine Club newsletter 43-4 in June 1980 included an inquiry by a member regarding a Howa M1 carbine he had purchased. The barrel is 19 1/2' in length and the receiver has been drilled and tapped for a scope mount. The holes for the scope mount are identical to the unique hole positions for the Howa Model 300 scope mount.

Bits and pieces of information have been shared regarding several of these Howa carbines. They were a later evolution of the Model 300 that were sold commercially in Japan in the 1970's. They retained the sporterized stock and finish, scope mount holes, as well as the Howa markings. The sights are consistent with those manufactured 1965-1966 under contract to the Royal Thailand Border Police (see next page).

This later version of the Howa Model 300 was purchased in Japan by American military personnel stationed in the Far East and brought back to the United States when they returned.
