PolarStar UGS™ Stock Rail

The UGS™ Stock Rail provides the indexing and length adjustment normally handled by the rail on a buffer tube. Swap between rails on your UGS™ to reconfigure the stock for Milspec CO2 inserts and Milspec stocks, or 2.000" diameter HPA tanks and 2.000" stocks such as the G&P R3 and similar paintball-style stocks.
All UGS™ stocks for M4-series models use the Original rails. All UGS™ stocks for HK417 models use the R01 rails.
