soooo, today i picked up 2219 razor crossbow aluminum bolts , they are the perfect size and shoot amazing out of it , no more issues not bad money like 8 or 9 bucks each , i was shooting 40 yards and it will shoot into the same hole , was quite impressive . the big difference is these arrows are 370 grain then add a 100 gr tip they are 470 instead of 270gr-100gr=370 gr . they carry super well to. at 50 yards they burry all they way to the fletching lol was shooting a 3/4 inch group at 50 and shot out to 60 and still money . its funny i walked into my local bow shop West Houston archery and told the guy what i was looking for and he knew the exact thing without missing a beat . those guys over there are pretty awesome. i shot 1 arrow about 40 times to see how it would hold up and it was perfect no issues. the pieces crap actual arrows that come with it i was getting 0 to 4 shots b4 it blew out the insert they are garbage. sooo if anyone has the air saber buy EASTON RAZOR ALUMINUM CROSSBOW BOLTS 2219. they are perfect and shoot amazing pull out the bolt nock and slid them on .
