A4 --> A5 Buffer Tube conversion

[LRRPF52]

If you convert it, that is modifying it and in the eyes of the Fed's it's against the law.

If you modify the brace into a stock, or a device with a plug in the space where your arm goes, then they can and have prosecuted this (domestic violence call, threw in firearms charge and lost that case).

Using a different RET does not modify the brace, and increasing the LOP certainly doesn't violate any laws.

OP: If you use an A5 RET, you will need the corresponding A5 buffer, which is longer than a carbine, but shorter than a rifle buffer.

Also, if you install a Law folding adaptor, the overall measurement of the length of the pistol will be considered in the folded position.
