Interesting problem - pistol length gas block on midlength rail?

[Gtracer]

Just kind of getting frustrated that everything I get into turns into a machining exercise. I can't ever just buy shit and build it.

It seems you like to build guns to your liking which is great that you have the knowledge to do so. You should not be getting frustrated seeing as you are obviously treading in areas that not too many have.

Seems like maybe this gun will cost more than it is worth unless you plan on making the parts on your own. I am sure any machine shop will be able to build the tooling for you but it will cost you.

Why's that a problem? Isn't 5/8"x24 standard for larger bores? Or are you saying they only make the compensator for 5.56, and it's 1/2"x28?

Yep, as most all linear compensators are only for 5.56mm. I guess 7.62mm is not popular in SBR's.

I mailed Hera about that linear compensator. They only make the Linear compensator for 5.56mm in 1/2"x28 pitch. .30 cal is 5/8"x24. So... might have yet another problem.

Buy your own CNC and be done with it....

I use to own one, and I've made a few as well. I have friends that could do the machining if need be. But, I do have a mill myself. Just kind of getting frustrated that everything I get into turns into a machining exercise. I can't ever just buy shit and build it.

Detent holes to press plunger plus a hex nut welded to the face of the knob followed by a cheap 1/4" extension and socket.

Now make it happen, take pictures and document it here. Get to work so you can pave the way for me. lol

You and DOHCTR bring the beer and I will watch...sounds like a plan right?

Why mid length instead of carbine? But even a carbine handguard won't work with a pistol-length gas system will it?

No, pistol is 4", carbine is 6". If I'm going through the damn hassle I'm going to get a hand guard that covers the muzzle. I'm going to do either a 9" or 10.3" barrel depending on where the muzzle falls on the handguard. I'd like to do a rifle length on a 10" barrel so my suppressor is inside the rail, but then it's heavy.

I might just replicate the Hera Arm's SBR exactly. If I used the mid length MOE handguard I could just pop it off and adjust it. Come to think of it... are there any 2 piece free float rails on the market?

I hate you a little. Let me know what you figure out for the FF tube, and make 2. I'll buy the other.

This thread has dissuaded me from the gas piston idea. I don't want to pay $500 only to have to rig something up to make it work.

It's a weird circumstance for me because I'm having to use a pistol gas block location and a mid length hand guard. Most of the time you use the proper gas block location for the handguard, and there are tons of setups that make that work perfectly fine.

I am not Dochtor or whatever his S/N is but a quick Goole turned up this:

Samson Star - 4 AR Pistol Free Floating Rail is a two piece free float rail system for the AR Pistol or SBR. The STARS-4 by Samson is a 4" length free floating pistol rail.

I know there are guys on here though that probably know much more than me...I am just good at ummm, ----- rigging things

Edit: looks like Adams Arms offers something though I cannot see because the peeps at work blocked me from looking at guns while on the clock....I bet they voted Obama too....

Yeah I've been through all of these already. I don't want a 4" rail, I think it looks ridicuous. Especially when you have 4" of additional barrel, and then 6" of suppressor in front of it. I don't have anything to hold onto. Not to mention when I'm hunting it would burn the shit out of me on a sling if I were shooting it.
