Reviews & Ratings for DoubleStar M4 Socom Stock Long — 1 review — Page 1

It's a sturdy stock that doesn't add a lot of weight. It's comfortable for those who like their ARs with rifle-length stocks like I do. I can't tuck up with standard stocks because it bends my trigger wrist too far, but this length is about 2.5" longer and that makes all the difference. I can come right up into my irons now and it's all good, baby.

I haven't bashed any doors down with it yet, but one day I'll get it out for tac training and see if I can find a doorknob to snap off with it.

I gave it 4 out of 5 stars because I have a binary trigger that only comes with standard length recoil springs, which meant I had to make my own spacer to bring the internal length back down to the standard. It's not hard to do, but if ACE made a spacer for this purpose it would make things a whole lot easier. For those without that problem, a standard rifle buffer and spring will work just fine.

For the record if anyone else has the same issue: the spacer should be 7/8" round x 2.5" long and one end should have a wear plate on it for the spring to ride against. Mine is 1/8" aluminum screwed to the end of a wooden dowel, but if you've got 7/8" aluminum rod, make it 2.5" long and you should be good to just drop it in.
