I dug out a customer's Regal Metal Works 6 position extension to compare to two M1014's I have laying around. The overall length is definitely different. The threads on the RMW do not extend down the extension as far as the OEM. No idea why they would deviate from the OEM pattern they copied.
So you might want to screw in the RMW about 6 full rotations, and see if that corrects your pistol grip issue.
OEM on the left. RMW on the right. Both tubes are set on an even flat surface. My two OEM M1014's are identical height.
Hi All:
Rumaging around on the Internet for these manuals is kind of a pain, so I'm linking them to this forum from my Google Drive. These links should be good forever, unless Google goes under or the Internet disappears:

NP3 is getting increasingly more limited in retail sourcing outlets. I recently cobbled together these 14" SBS Mossberg Shockwave's, .410 & 20 gauge with NP3 coating of all the action parts. The .410 was done by Robar (no longer doing NP3) and the 20 ga. sourced by Vang Comp while they were extending the forcing cone / porting the barrel last year. Keep them handy in one of my load-out rooms for varmints and 2-legged malcontents. There is no aluminum tri-rail option for the .410 mossberg so for fun I fabricated a 6061 aluminum bushing on the lathe to mate the Mossberg .410 to the 20/12 gauge tri rail forend tubes.
You know remarks like the government's going to be coming to your place first really don't help anybody and I've never heard of someone who actually had the ATF come to their house to look at their NFA stuff. I agree the NFA is unconstitutional but by the logic in that post you would need to buy suppressors and sbr's illegally to tell the government you don't approve. Everybody is free to make their own choice though so as long as your happy with yours that's all that matters.
The misinformation with title 2 firearms never ceases to amaze me.
It is only a short barreled shotgun when it has a short barrel. Put an 18 on it and it is not a short barreled shotgun. Take it anywhere a shotgun is legal, even sell it with the 18 if you like. NFA would like to know it’s been “converted” back to a title 1, but that isn’t even necessary. Unlike machine guns and NFA’s “once a machine gun always a machine gun” position, an SBS or SBR is only a title 2 when configured as a title 2.
You do not give up any rights. .gov can’t come into your home anytime they wish. Still America folks, probable cause and a warrant is necessary to enter your home.
I agree, you are free to bounce back and forth 14 to 18 to 14 and back. My point is that once registered as an SBS, the receiver will always be an SBS. All NFA rules,regulation and laws will forever follow that receiver. You cannot put the 18 back on and sell the weapon without a form 1 NFA tax stamp transfer.
OK....form 1, form 2, form 52, those numbers are irrelevant. Fact of the matter is, it's the receiver that's registered not the barrel.
Try out your theory. Swap your 14" barrel back to 18", take it to a gun shop and offer to sell it to them. Agree on a price, then tell them, "oh by the way it's a registered SBS". I'm fairly certain they will kindly change their mind.
I could be mistaken but I think not.
