JD Machine build.

Recommended Posts

Parts are starting to come in, with more on the way, and more to order.  I started out wanting to build a m110 clone (rather a mk11 mod 2, since I'm a Marine.)  So far I've ended up changing everything except the barrel profile.  However I am still trying to stay in the medium weight GP type arena.

So far I have:

* JD Machine matched upper and lower (looks and feels awesome) - JD

* DPMS LPK, as well as the .308 compatible pieces - MidwayUSA/JD

* Ejection Port cover and HW - JD

* Fwd Assist and HW - JD

* Geissele SSA trigger - Brownells

* LR-308 rifle buffer/tube/spring- Midway

* Magpul PRS .308 - Midway

* DPMS phosphate BCG - Rainier Arms

* SI Defense 20" M110 SASS contour barrel - Midway

* DPMS rifle gas tube and roll pin

I still need:

* Rail system - looking at DD Lite or Samson STAR10 (if it will fit) any other suggestions that will mount flush with the JD upper

* 0.875 gas block, will depend on the RAS I end up with. Although, I would love to get my hands on one similar to the M110, if anyone can think of one.  I don't need the suppressor slotting though, since CA will probably never allow me to attach one >:(

* Muzzle device - Leaning towards the Smith Enterprise Vortex, any thoughts?

* Bi-pod/ adapter

* Scope/rings

* BUIS (not a huge priority right now)

* Lots of bullets!!! I will probably start reloading due to this build and the 6.8 I'm also doing.

Taking a chance on the Si Defense barrel because I couldn't find too many reviews on it.  However everyone seems to love their other products so I figure I would be a ginny pig and try it out.  Please let me know if anyone has had a bad experience with their barrels and hopefully I wont have installed it yet.  I would have preferred to get a matched bolt/barrel but the price on this thing was too good to pass up ($205 w/coupon) before shipping for a $300 barrel. 

I am open to any suggestions you guys may have.  I will say that I have already learned a lot just from scrolling through as many posts as I can.  The guys down at JD Machine have been extremely helpful.  Plus they have a sweet set up down there.  I would definitely suggest checking the place out if you live in the San Diego area.

Oh, and I will not forget to post pictures as it comes together!

Yea, I can't wait to actually fire with this SSA.  Just having the lower built, I agree with you, that I would like to swap all my triggers out with them.  Wish the Marine Corps would swap all of their rifles out with them.

Alright, it's done! Pictures as promised, taken with my phone so the quality isn't great.  The specs remain the same as the original post, with the following exceptions.

* Barrel- Fulton Armory 20" M110 1:12, blackened through JD Machine.

* Bolt- Fulton Armory

* Gas Block- Fulton Armory clam style .875

* RAS- DD 7.62 Lite

* Muzzle- Smith Vortex

* Scope- Leupold Mark 4 3.5-10x40mm LR/T M3

* Scope mount- Night Force Uni-Mount 20 MOA

* Bi-Pod- Harris S-Series BRM w/ Larue Tactical QD

This thing is a blast to shoot.  Haven't gotten a true zero yet.  Only a BZO, by having a spotter call adjustments.  It's pretty close, but we weren't shooting an true ranged targets, and it was with the bi-pod on a wobbly table.  But, I love it!

Thanks for everyones inputs.

I'm always down to meet up for a shoot Robocop.  Although, I probably wont have a chance to make it up to NorCal until after my upcoming deployment. But let me know if you venture south in the next two months.
