The OPS-416 Gas Piston System fits most standard AR15/M16/M4 carbine length 10.5″ thru 16″ rifles with a barrel outer diameter equal to, or less than .875″ . This covers more than 95% of all AR15/M16/M4 rifles ever made. There are some exceptions to this and we will note them under the “fit chart” area as they come in. Most likely, if you have an unmodified gun from a quality name brand, the OPS-416 will fit just fine.
You simply remove your gas tube, install the OPS-416 in it’s place, and you’re ready to go to the range.
