P80 Thr/Flu Brl N/Sght 15rd - polymer 80
About this product
The P80 Thr/Flu Brl N/Sght 15rd is a Polymer80 ghost gun kit requiring final machining and assembly to create a functional handgun. Production has been temporarily halted, making this one of the final available units. This kit includes all necessary components except tools and expertise.
What is the P80 Thr/Flu Brl N/Sght 15rd used for?
This kit serves as a starting point for building a custom handgun requiring no serial number registration. It appeals primarily to experienced gunsmiths and enthusiasts seeking complete control over their firearm's construction. The 80% lower receiver requires milling to 100% completion before assembly.
How does the P80 Thr/Flu Brl N/Sght 15rd compare to the Polymer80 PF940V2?
The Thr/Flu model includes threaded barrel and suppressor-height sights while the PF940V2 ships with standard components. The Thr/Flu's 4.5-inch threaded barrel accommodates suppressors better than the PF940V2's 4.02-inch non-threaded barrel. Both require identical machining time of approximately 2-3 hours with proper tools.
What does it weigh and what are the dimensions?
The unfinished lower receiver weighs 8.2 ounces with overall kit dimensions of 9.5×6×3 inches when packaged. Completed weight with all components reaches 22.3 ounces unloaded. The frame requires milling to final dimensions of 7.3×1.2×5.4 inches.
Who is this NOT for?
This kit is unsuitable for beginners without machining experience or proper tools. Those seeking a ready-to-fire firearm should consider our .308 80% Lower – Billet instead. Legal restrictions in certain jurisdictions also prohibit ownership.
What's in the box?
The kit contains one 80% polymer lower receiver, one threaded barrel, suppressor-height sights, and all necessary small parts for completion. Specifically: 1 frame, 1 barrel, 2 sights, 1 parts kit with 15 components, and 1 magazine. No tools or jigs are included unlike our see Polymer80 80% Lower Receiver and Jig Kit.
Is the P80 Thr/Flu Brl N/Sght 15rd worth it at $569?
At $569, this kit represents a 12% premium over standard Polymer80 kits but includes upgraded components. The threaded barrel alone retails for $189 separately, making this cost-effective for suppressor users. Final production status adds collector value according to our more on How PolyLock Frames Perform in Salt‑Water Environments data.
