While distributing thousands of lower parts kits to builders and gunsmiths throughout the country, Cool F/X began to experience supply disruptions, running out of certain kit variations. Sometimes supplies would dry up completely, leading to a lot of frustration on ours and our customers' behalf's. In order to mitigate this issue, we decided to offer a branded lower parts kit (LPK), made out of the best materials possible.
In addition to helping us maintain more consistent supply, MIL-SPEC, overall quality, and an amazingly low price, the premium LPK includes several standard features that few, if any, LPKs can offer. That makes these kits unique and perfectly suited to a premium build.
Compatible in MIL-SPEC lower receivers with calibers .223/5.56, .300 AAC, 7.62x39, 5.45x39, and 6.5 Gendel.
Here are specifications of this superior kit:
- Every component in the kit is produced from MIL-SPEC steel
- The hammer and trigger are 4140 steel heat-treated to MIL-SPEC
- All other parts are 8620 steel heat-treated to MIL-SPEC
- Each part is finished in MIL-DTL-13924 specification black oxide
When the best is required for your firearm, don't settle for less. The premium LPK offers a product that provides MIL-SPEC quality and incredibly good value.
