[R700]

I read the sticky in the general section and really didn't find much about upgrades other then a few external stock options.

I have ordered this GBB product and was considering installing the RA Tech Hop Up and the RA Tech 6.01 380 mm TBB.

A few questions for the owners that have done something similiar.

1) will the 380 mm barrel fit without an extension, ie silencer, etc?

2) will the ra tech hop up suffice or should i get another brand? I am planning on using the .36-0.4 bbs.

3) will these upgrades make a big difference or just a slight difference? My plan is to get this GBB to 150 ft range fast and accurate. Is this a reasonable expectation with these mods?

The product was purchased as a run n gun DMR but mostly anything past 60-80 ft as per our MEDs. It will not be a primary tool, slung on my back and used as needed for the long range. You may have read a post in the general on the mp5sd6 that i was going with but i have decided to go this route now.

Don't flame, i am new to GBBs and airsoft and would like opinions based on experience with this model. Thanks for your time.
