    Would love to see some M-LOK incorporated into this design.

    Works well

    Posted by F on Nov 12th 2020

    Fitment is spot on. Just a touch snug so I know it was machined well. I wish the nose was longer to benefit to more real estate on the forend and sling studs or mlok slots like the Kidd chassis. Its very lightweight. No issues fitting grips or buffer tubes onto it. I like the antirotation ring on the rear of the chassis and is why i chose it over the kidd. One place where i felt this chassis wasnt top notch was the finish. I can see sone light spots in the cerakote. I can see that they cerakited over their red anodize chassis with the cerakote. Some light areas where the red shows through. I could also see where the receiver looked like it was bumped or drop where the edges of the chassis werent perfect. It almost looks like it was used or a blem that was refinished. But where the machining matters is fine. Mostly cosmetic issues only. PMACA: If you receive a chassis where you can see through the Cerakote on the visible surfaces when it is assembled, this is a manufacturing defect. If your chassis has a manufacturing defect, or you are just not happy with your purchase, you may return the unused chassis for a full refund.

    Awesome product! Great fit and finish! I only wish the long nose would be offered for a factory ruger receiver.

    Had a rough burr along the the side that should have been cleaned up but was finished over instead. Ok but not a high level of refinement based off this blemish

    PMACA Long Nose chassis review

    Posted by Keath on Sep 18th 2020

    I love it. I know there are some questions regarding the use of a tangless receiver with this chassis. My setup is with a tangless receiver, 4.5" BBL, and 5" suppressor, and I have no problems with it tilting or anything like that with such a short BBL (provided the take-down screw isn't over-torqued - a key consideration). A 16"+ BBL may very well be an entirely different story. But mine is perfectly fine, and the reason I like the LN chassis with this setup is that the fore-end reaches almost to the end of the BBL+suppressor combo, providing additional purchase and protection for the offhand, while also allowing just a sufficient smidgen of real estate on the end of the suppressor to easily remove it without necessarily taking down the chassis from the action.

    There is a large burr on the bottom of the chassis where I would put my hand when carried. The package arrived in good condition no shipping damage. PMACA: If you find a manufacturing defect, please feel free to return the chassis for a full refund.

    Long Nose Chasis

    Posted by Spencer on Sep 1st 2020

    This is very well machined and finished. I had purchased a standard/original chassis about 2 years prior and have loved it. This long nose version did not disappoint. It drives you to spend more either by using KIDD products, or by paying a machinist to add the tang to your factory receiver, but it was worth it. I stuck with a factory Ruger Charger for now and had it machined. The only improvement I could hope for would be for them to check their picatinny rail specs; both have been extremely tight when adding name-brand aftermarket accessories.
