Wolfgang1952 Posted July 20, 2016 Report Share Posted July 20, 2016 Welcome from Louisiana. Cut yourself a broom stick spacer. When I went from a collapsible stock to a rifle stock on my AR15-45. Could not use rifle spring and rifle buffer. Rifle stuff just not compatible with 45acp. Had to stay with the shorter spring and buffer. So I used a piece of broom stick to make the difference in the length of the tubes. Quote Link to comment Share on other sites More sharing options...
blue109 Posted July 20, 2016 Report Share Posted July 20, 2016 (edited) All milspec extensions will be 7" on the inside and 7.25 total. That's the "spec" part of milspec. Order from a reputable place and those dimensions will be correct. Edited July 20, 2016 by blue109 Quote Link to comment Share on other sites More sharing options...

MikedaddyH Posted July 20, 2016 Report Share Posted July 20, 2016 Welcome from AZ ! You may prefer to use a stack of quarters on the inside for you RE tube. Quote Link to comment Share on other sites More sharing options...
hottrodd1090 Posted July 20, 2016 Author Report Share Posted July 20, 2016 (edited) thank you all for making me feel right at home and thank you for the replies.if i order an aramalite or vltor i think they come in at 7 3/4" so i guess i will have to take one of the suggestions or come up with my own to take up the 3/4" difference.

blue109 Posted July 21, 2016 Report Share Posted July 21, 2016 Just curious why you need that extra .75 on the total external length? Your stock will fit the standard milspec tube at 7.25 just fine. Its the internal depth that's important for function. A VLTOR milspec tube should still be those same dimensions. I have one at home, I'll try and confirm. If you are talking about the VLTOR A5 length receiver extension, it is a little longer internally but fits milspec sized stocks. Same length as the armalite AR10 carbine tube, and designed to be used with a special A5 buffer and spring on an ar15 rifle. I'd personally stick to the standard milspec extension with the standard 7" internal depth, and add the thick shoulder pad to the stock if you need the extra length. No point in rigging stuff with quarters or spacers if you don't need to. Quote Link to comment Share on other sites More sharing options...
hottrodd1090 Posted July 21, 2016 Author Report Share Posted July 21, 2016 i am just trying to replace what i have and you are right i will just use a mil spec tube and i already put a thicker pad on the buttstock so i'll be good to go thank you all for your support Quote Link to comment Share on other sites More sharing options...
MikedaddyH Posted July 21, 2016 Report Share Posted July 21, 2016 With that extra play in the sping to buffer area. The effect is the buffer bouncing ,which will destroy the end of the buffer where the weights slide on the inside of the buffer. By placing a few quarters at the back of the RE behind the spring it adds tension to spring and takes away slack of the mismatch or worn part. You will have to experiment with the amount of quarters needed. Quote Link to comment Share on other sites More sharing options...
