Welcome to the Marlin Firearms Forum jenniesue !!
Never seen a plastic receiver...maybe it was a plastic covered metal receiver.
Did you ask the salesman what it was made of !?
If you can, take a pic and post it here. Also see if he can nail it down to one of the following models:
The Model 60 is currently available in 9 distinct versions:
- Model 60, the basic rifle
- Model 60C, the basic rifle in a camouflage version
- Model 60SN, the basic rifle with a black fiberglass stock
- Model 60SB, the rifle in a weather-proof stainless steel version
- Model 60DL, the basic rifle in a Monte Carlo walnut stock
- Model 60SS, the rifle in a nickel-plated, stainless steel version with a grey/black laminate stock
- Model 60SSK, the rifle in a nickel-plated, stainless steel version, with black fiberglass stock
- Model 60S-CF, the rifle in a nickel-plated, stainless steel version, with a black carbon-fiber-patterned stock
- Model 60SSBL, the nickel-plated, stainless steel version with blue/grey laminate stock (sold exclusively from Cabela's)
- Model 60DLX, the newest Marlin 60, celebrating the 50th anniversary of the Model 60. Has a premium walnut stock and gold fill on the roll marks, otherwise same as base model.
Historically, there were also other versions that were sold:
- Marlin Model 99 and 99DL - this was the first version of the Model 60, offered in a walnut stock, 1959 to 1961
- Marlin 99G - Very similar to the 60
- Model 99M1 - styled to resemble the US Army M1 carbine, with eighteen inch barrel, handguard, barrel band, nine shot magazine even with the end of the stock, and receiver sight mounted on the scope grooves.
- Model 99M2 - styled like the 99M1, but with a box magazine.
- Glenfield Model 99G - precursor of the Model 60G.
- Glenfield Model 60G - this was the name used on Marlin-made Model 60 guns intended for sale to mass-merchandisers, 1960 to 1965, with a birch stock instead of walnut
- Glenfield Model 60 - one of the Model 60 versions manufactured from 1966 to 1982
- Glenfield Model 65 - manufactured in 1968; it was essentially identical to the Model 60 with the exception of a brass exterior magazine tube; it was made for Oklahoma Tire & Supply Co.
- Glenfield Model 75C - Carbine version. Shorter 16" barrel and 9 shot mag tube. No bolt release lever in trigger guard. Supplied with sling swivels.
- Marlin Model 120 "Revelation" - Manufactured for Western Auto Supply in the early 1960s, had a brass dot front sight instead of the hood sight, and the barrel is stamped WESTERN AUTO SUPPLY CO.
- Marlin Model 600 - Made specially for Big 5 Sporting Goods between 86 and 89. This model is very rare because of the short production run, and little info is known. Came with a supremely durable gold-plated metal trigger instead of the standard polymer trigger, and a stainless steel breech bolt in lieu of the blue steel breech bolt on the Model 60.
