Wow with a slide fire even rolling your own bullets could get to be expensive and time consuming but I would like to do it once!!
Grover.... if ya did It ONCE.... you'd be addicted like me... trust me
Hey stavman, if I'm understanding you correctly you swap your slidefire between the 15 and 15-22. Did you do trigger work to the 22? I ask because I have both also and the slidefire and runs great on the 223. I threw it on the 22 and was able to get mostly 3-8 shot runs but I'm running factory trigger, haven't gone down around 3 pounds yet. Technique REALLY comes into play on the 22 tho
Sorry Didnt see this post Bud... race Weekend so been selective on my POSt reading....LOL
yes to Both...
I have a timney trigger in my 15-22 and it DUMPS my 50rd drum easily and all 19 of my 25rd mags........ get the Timney or Comparable Trigger... and FULL RETARDATION is at your Finger tips

once you have the Timney trigger... no technique is needed..... you may get some light Strikes on occasion..... but mainly if Gun is dirty or Too oily....
i basicaly moded a Handgrip with a dremel and swap the Slide fire between my 2 M&P's..... STUPID FUN!!!
Can you aim the rifle with the slide fire on burst of 2 or 3?
i can Burst 3-6 rounds and hit most anything at 25yds..... hit a target at 50yds..... Hit a, well, person size target at 100yds
I can FULL mag dump at 25yds and Disinigrate most anything Now......
Ill try and get a Picture of a 1gal WD40 can tomorrow.. or a video of a Watermelon....
yes... it is Not cheap ta dump 30rds in 4 seconds.... BUT FREAKIN EH IS IT FUN!!!!!
I wish there was a range that just rented the slide-fire stock. I don't want to buy one, but I wouldn't mind trying it out.
Come to AZ... Anyone...... PM me here... we can hook up... and you can try it...... But only if you are able and willing to BUY one when ya get back home.... becouse....
YOU WILL
