Question: Are there any aftermarket string dampeners that fit this bow?
Document: Fast, and accurate. This bow is deadly fast. I also like the scope that comes with it.. for hunting u can't beat it
This product has an excellent scope and has rifle like accuracy. Can't wait to take it hunting.The assembly instructions were very clear and easy to follow. I would definitely recommend this cross bow.
TOTALLY AWESOME!!! I have neen hunting for 26 years owned several Bows and one other crossbow.This one is the best for the money,took about 20 shots to sight in.The power is unbelievable i also purchased the Block Crossbow target after abouot 60 shots started blowing thru target would not recommend this target with this bow.If you want a crossbow for power this is it.The bolts that come with it are not my favorite I purchased some with bigger viens that do so much better for accuracy.
loved the compact size. assembly was a breeze and the scope was dead on at 20 yards. really quiet. great price for a complete crossbow setup.
Just got as a Christmas present. Would have given it 5 stars but it shoots to hard for my target and its rated for 400 f.p.s. The target stops bolt but it stumps up so deep I cant hardly pull them out. Make sure you have a GOOD target before shooting. Scope is very nice and I'm not going to complain about the power. I believe anyone that gets one of these crossbows will be very satisfied.
First crossbow, so I have nothing to compare it to really other than my compounds. It's a screamer though. After sighting it in, it launched bolts in very tight groups. I've tested it up to 40 yards so far. Easily as accurate as I can be with it.Assembly was very simple and fast.
Extremely pleased with crossbow. Very fast and extremely accurate. With a solid rest, it can shoot accurately up to 60 yards. I absolutely love the scope on it. I would recommend this crossbow to anyone.
Bought the carbon express sls for father inlaw for Xmas, I've shot  the horton vision before but mostly hunt with compound, shot the sls 60 times was very impressed, 1.5&#34; groups at 50 yrds shooting off a snow shovel handle, scope was good no problems , compact and ergonomicly correct would give 5 stars but as comparisons go there's probably more expensive lighter, quiet'r crossbows
Answer: no
