Welcome. Nice first post. I see we have some similar rifles and accessories. Harris style bipods are great. Just got one and it looks really nice. Very sexy indeed 
As for your question on the pdi or laylax parts, I would say either. I have used laylax parts and love them. Woogie, another member on here, loves his pdi parts. Which ever route you pick, I would stick with it. For example, all pdi parts or all laylax parts. Makes things simpler for you.
Anything else, let us know. And would love to see pics when you can get them up.
P.S. 500th post!!
