S&W M&P15 Sport II 5.56 NATO Black AR-15 Semi-Automatic Rifle

A: The manufacturer's website only mentions a chromed firing pin. (Chromed Firing Pin, Armornite® Barrel Finish, and Barrel Material: 4140 Steel) https://www.smith-wesson.com/firearms/mp-15-sport-ii

A: If they were chromed it would be $200.00 more like this AR, which is well worth it if you will use the gun hard. https://www.budsgunshop.com/catalog/product_info.php/products_id/7000/Colt+LE6920+Law+Enforcement+30+1+223REM5.56NATO+16.1%22

A: The barrel seems to be fine for me. Have well over 1000 rounds through it with no issues. Just make sure you break it in properly. Even putting 150 rounds through it in 5 mags in quick succession it didn't lose accuracy. Hope it helps!

A: 4130 is chrome moly which is pretty soft. The description says it's 4140 steel. The mil-spec standard is 4150. the last two numbers are the carbon content. More means harder and more resistance to wear so the 4140 barrel will not stand up to the abuse the 4150 will. 4150 will stand more heat (100 degrees more according to specs), so sustained fire is less likely to hurt the barrel.

A: If you make a habit of blasting 4 or 5 magazines at the end of your shooting sessions you need a "machine gun steel" barrel which means chrome lined. The guys who do sustained rapid fire that I know, don't make a complete 3 gun season on a barrel with 4140, 4150 or 416 stainless. My chrome lined 1:9 barrel is still good after years of hard use. Remember that chrome is for erosion and heat resistance. It still needs cleaning but will clean up quickly with a bore snake.

A: Just type "California Approved" in the search window. Then filter results to long guns. All ARs legal for you will be displayed.
