This is in reference to MP5 clones. So I know Maryland requires SBR's to be 29" muzzle to stock fully extended. Known as Overall Length or OAL. The issue a lot of us are running into is, H&K factory options don't get you there. So some are reverting to AR-style stocks, but I personally think they look goofy and unauthentic.
Then I saw a guy on here who rigged up an A2 stock that could telescope and lock open for the sole purpose increasing overall length. Say you did something like that, but even simpler. Like a buttpad with screws to be "permanent".
1) Say I added a permanent extension to an A2 buttstock to give me 29" OAL. Got the approved form 1, and then swapped out for an A3 stock that gives me an OAL of 27"?..provided I keep the A2 stock. (My reasoning is it's not a permanent change to overall length so ATF notification is not required. Like swapping AR15 uppers on one host lower.) However, if it came into question, I could pop one takedown pin and return to original configuration.
2) Under the same concept, could you make your own buttstock extension? Take a 2-3" chunk of rubber, drill one or two screws through it to bring the OAL out to a "permanent" 29" + OAL. Get it ATF approved and unscrew the rubber extension, but retain it in case it ever came into question.
Thanks. Looking for legal alternatives.
