"Just got this a week ago. The construction is beautiful. Very easy to install. The battery holder is some what small and will hold a smaller stick type battery fairly well.

Makes your gun stubby. Perfect for cqb.
Comes with everything you need. inner barrel, outer barrel, etc.
Excellent construction.

Cost. Its very well made but it is pricey.
Weight. The front end of this thing is heavy. Heavier than a zombat.

All in all a very good buy if you want something for cqb.

"This conversion kit is absolutely beautiful and of very high quality, I get complements every time i go to the field. There was a lot of unseen costs to the kit and work I would like to mention to save people hassle. First I had to get a lipo not even a small type 8.4 volt fits in the battery compartment, it will comfortably fit the smallest 7.4 volt lipo at 1300 mah brick type. The second issue is if you have a quick change spring system the back of the gearbox will stick out further which means the back of the conversion will not fit. I had to Dremel the heck out of it and customize a washer to hold it in place. So the moral of the story is this...

Very maneuverable
Beautiful kit, very high quality

Very limited lipo only battery compartment
If you have a quick swap spring system your in for some metal work

The kit would have been 5 out of 5 if it fit my ares amoeba stock
