Cutaway view helps to identify what makes the P415 a robust platform and understand how it operates.
This is what makes the P415 a "System" and not a "Parts Kit".
Simple regulated short stroke gas piston design having only 3 parts all coming out the front of the gas block.
Oversize Heat Sink barrel Nut that does three functions. Reduces/Radiates Heat, Guides the Op-Rod (almost 4" of guidance), and helps to Reduce Flex / Stress, with our free floating, two piece M.R.R. (Modular railed Receiver) Platform.
The free floating, two piece M.R.R. (Modular Railed Receiver) with backbone, is 5X's thicker then a Mil-Spec flattop upper.
M.R.R (Modular Railed Receiver), is .300" thick between charging handle and top of M.R.R..
The mil-spec flat to upper is .06" thick between the charging handle and the bottom of the picatinny slots.
The free floating, two piece M.R.R., having a continuous one piece top rail, sleeving onto the oversize heat sink barrel nut, and indexing and attaching to the lower portion of the two piece upper receiver provides a extremely robust platform, that helps to eliminate flex and stress in the barrel extension/bolt area of the upper receiver. The cutaway view helps to identify how and why.
The M.R.R. takes less then 3 minutes to assemble.
