Only Remington knows.
the remington model 510 is a 22 plinking rifle used by adults and youth alike. they were not known to have been used by the military, but it's possible.
There is no Remington Model 6 pistol, there has been however cases however of Remington Model 6 rifles converted to pistols by gun or "home" smiths. NOT Remington. As such the value is whatever someone will pay, but generally not much.
Remington Arms has been manufacturing the Model 700 series since 1962.
The Remington model 720 rifle was never offered in the 222 chambering. While it would have been technically possible to convert, the work required would have been totally out of any reasonable proportion to the result. Perhaps you actually intended to refer to the Remington Model 722 which was produced in that caliber. Price guides area available for reference to the current value for one of these rifles.
You are referring to the chamber brush that was included with 742 rifles when purchased new. The Remington Model 742 is no longer available and was replaced with the Model 7400, Model 4 and the Model 74. These rifles have the same outward configuration as the Model 742, with slight internal changes to the bolt locking lugs. You may be able to get a chamber brush directly from Remington for the Model 742. If they no longer offer that Model specific (742) brush, those for the 7400, 4 and 74 will work. The Model 7400, etc. has recently been replaced by the Model 750 which is very similar to all the above semi-auto rifles with an upgrade involving the gas-system. You need to specify which caliber you have. Cost will be around $10.00 plus shipping.
10, 108 of these rifles were made in 1976 only. Value if in "AS NEW" condition would be around $450.00. If you have the original box and papers included, you could realize another $100.00 from a Remington collector.
Quite a few different ones. Some of the more notorious ones were war souvenir Japanese Arisaka rifles, which had been converted to fire the .257 Roberts, as the Japanese ammunition was a bit scarce on the commercial market. I know the Ruger rifles were made available in .257 Roberts, including the Mk. II and M77, as were the Winchester Model 70, Browning Model 81, and Remington 700. Sako made custom rifles in that calibre, as well.
The Model 1100 has been made since 1963 and is still in Remington's catalog.
There have never been any recalls on the Remington Model 742 that I'm aware of. The Remington 742 is now an obsolete model and was replaced with the Remington Model 7400. The bolt received an upgraded design along with the magazine catch/release. At one time Remington was offering a Model 7400 as a replacement for the Model 742, if you sent them your Model 742 along with $350.00. Is there a problem with the 742 that you have?
If you are asking about the US model of 1917,which was made by Winchester,remington and Eddystone?Then these rifles have been selling for between 400-750 dollars for a model that is all original with the correctly marked equipment that came with the rifle.W-Winchester,R-remington,E-Eddystone.These will be found on alot of the parts of the rifle.The receiver and barrel should be of the same markings also.The stock should be original and not refinished.
The Model 1100 has been in continuous production since 1963.
