n4p226r 105 Posted April 24, 2016 Has anyone pinned a b5 sopmod? I'm debating of sticking with the vltor imod I have on my other rifle or going with the sopmod this time around. The imod is real easy to pin. Wondering what you think about sopmod vs imod too. Quote Share this post Link to post Share on other sites
High Exposure 5,661 Posted April 24, 2016 I have an LMT SOPMOD and a B5 Bravo on work guns, and 2 B5 Bravo stocks on personal guns. I prefer them over the VLTOR IMOD. That being said, I wouldn't not put an IMOD on a gun - They are nice stocks. As far as pinning, the Bravo is easily, drill through the stock into the receiver extension and pin. The SOPMOD, I dont know. Looks like it would be difficult. Quote Share this post Link to post Share on other sites
n4p226r 105 Posted April 25, 2016 Are the sopmod big? Some pictures they look huge. Since you have the LMT and a bravo do you prefer one over the other? Quote Share this post Link to post Share on other sites
n4p226r 105 Posted April 25, 2016 I wonder if pinning the lever in place would be sufficient to properly secure it. You wouldn't even need to drill the buffer tube and with the thickness of the material it should hold. Quote Share this post Link to post Share on other sites
Displaced Texan 11,731 Posted April 25, 2016 I have drilled through the release pin mechanism, and pinned that with a roll pin. Doesn't mess up the stock visibly, nor does it drill into the RE. It prevents the mechanism from working, effectively latching the stock in place. Quote Share this post Link to post Share on other sites
n4p226r 105 Posted April 25, 2016 Did you drill behind the lever? Have any pictures? Did you remove the spring first? I haven't taken the sopmod apart but I'm guessing it's similar to the m4 stock. http://www.brownells.com/.aspx/pid=0/sid=809/schematicsdetail/AR_15_Sliding_Buttstock_Assembly?avad=avant&aid=41227&cm_mmc=affiliate-_-Itwine-_-Avantlink-_-Custom+Link 1 Quote Share this post Link to post Share on other sites
Displaced Texan 11,731 Posted April 25, 2016 I'm traveling at the moment so can't take pics. I drilled through the plunger mechanism and pinned it in place. I think I found the procedure in Calguns. Quote Share this post Link to post Share on other sites
n4p226r 105 Posted April 25, 2016 thanks. ill check calguns. it would be possible to machine a new mechanism inside that wouldn't allow the lever to work, but its a lot more work than just pinning it. Quote Share this post Link to post Share on other sites
n4p226r 105 Posted May 4, 2016 I assume this is what you did. http://img.photobucket.com/albums/v217/wsaraceni/496DE255-558C-4656-8D9D-6F161E529421_zpsc73q6rfa.png Quote Share this post Link to post Share on other sites

n4p226r 105 Posted May 4, 2016 That roll pin to remove the lever is pretty impossible to remove. Quote Share this post Link to post Share on other sites
Displaced Texan 11,731 Posted May 4, 2016 What are you using to get it out? Quote Share this post Link to post Share on other sites
n4p226r 105 Posted May 4, 2016 A roll pin punch. I need to get my punch with the little nub on it tomorrow. Quote Share this post Link to post Share on other sites
Displaced Texan 11,731 Posted May 4, 2016 Punch and a small hammer did the trick for me Quote Share this post Link to post Share on other sites
n4p226r 105 Posted May 4, 2016 Did you remove the spring or just drill through it Quote Share this post Link to post Share on other sites
Displaced Texan 11,731 Posted May 4, 2016 I removed it. Quote Share this post Link to post Share on other sites

n4p226r 105 Posted June 5, 2016 I figured I would update this in case people look in the future. Remove the internal spring and drill and pin the location in this picture 100% invisible when you put the lever back on.

With my current knowledge I’d most likely ruin the stock and drill around it, since it’s metal. I know this is years later but I have to give it a shot.

Hello, I’m attempting to pin a SOPMOD myself and I’m having some trouble. Would you be able to share exactly how you would drill through the release pin mechanism? I know the plunger inside is round and if I attempted to drill through as is, I’m assuming the bit would slide off to the side before starting to bite into the pin. Not entirely sure how to end up with the results that the other gentleman had posted before. I know I’m 7 years late to the party but I was hoping you could help me. Thank you.

Displaced Texan 11,731 Posted May 25, 2023 It’s been a long time, and I since moved to Texas where I unpinned all that crap…. That being said, I think I used a small drill to make a hole at the spot I wanted. Made sure to dimple the plunger mechanism inside. Then, I removed the plunger, slowly drilled the rest of the way through it. Once I put everything back together I tapped a roll pin in. I’m out of country on vacation at the moment, but when I get back, I can give you a visual of how I did it. Quote Share this post Link to post Share on other sites

Hey, sorry I kind of forgot about this. My stock wasn’t a Sopmod, it’s a Vltor, but I imagine it will be similar. Here’s where I drilled on mine. I used a 4-40 set screw to prevent the latch from moving. You could use some JB Weld to putty over the screw, or for that matter, you could just leave it be. I believe as long as it’s not readily adjustable without using a tool, you’re gtg. Quote Share this post Link to post Share on other sites
