MK18 Conversion Project Advice

[sunburnthammer]

Hello there,

I am considering converting my G&P Sentry into a MK18. What I am considering changing is the front ris, body and stock.

Parts: MAdbull MK18 RIS, G&P body or Madbull Daniel Defence body, and a Crane style stock (chinasoft or G&P)

Concerning the RIS first, would the madbull one fit a G&P body?

With referency to the bodies, would the Madbull body take the G&P internals, stock tube, and Magpul pistol grip?

thanks in advance

Arnie
