More Air Efficiency
VERY LIGHT WEIGHT
This thing is awesome!
This is definitely an upgrade you want to get if your thinking about upgrading your DM7. First thing you notice is that its tiny, the stock bolt weighs about 30 grams where as this bolt weighs about 10 grams. The air efficiency is great i find i get about 1500-1700 shots out of it before i need to refill on air. Instillation is easy, you just take apart the stock bolt and screw this one on. Also with this bolt you will be able to significantly lower your dwell. I like it alot better than the orange bolt, its smaller and more efficient.
If your looking to get a good upgrade to your DM7 definitely pick one of these up, you wont regret it.
