Big Box from MPX Followed Me Home Today

[RobertJames 14]

I've had my eye on the billet lower from Midwest PX for a while now, and finally pulled the trigger.  Also ordered some accessories to go along with it.

 

Luth AR MBA 1 Skeleton stock

BCM pistol grip

MPX LPK

MPX rifle buffer assembly

 

The products arrived in just a few days and were well packed.  Would definitely order from them again.  Waiting on a few more items to arrive to begin the build, hopefully this weekend.  Stay tuned, pics to follow.

Thanks for the order!  Looking forward to seeing it built up!

I've got this waiting for a muzzle brake at a local shop.  It looks nice, can't wait to see how it does.  I also have a nickel boron bcg to go in it, also from PSA.  Last but not least, I'm waiting for a Geissele SSA-E trigger to be delivered.

Sounds like a great set up. Those Geisseles are amazing

is the process for pinning that stock the same as any other adjustable stock?

That stock is fixed. No pinning is required.

Trigger arrived today and I installed it in the lower.  All I can say is wow, I get it now.  Can't wait to try it for real.

[RobertJames 14]

I got to work on the lower last night, here's some photos.

Commercial buffer tube?

Commercial buffer tube?

 

I think it will work with either.  I honestly don't remember what I've got.

 

Picked up my uppers from Mastodon today.  Giggity.  Photos later tonight.

[RobertJames 14]

Finished project (for now) I would like to upgrade the scope eventually.

 

 

 

 

 

Going to go to the range today and see what it can do.

[MidwestPX 172]

Nice builds! I love seeing PX lowers built up!

[T Bill 649]

GL-Mag fits either tube out of the box.

I had a few spare parts lying about, and Anderson lowers were $50.00.  So here is another rifle I built.  It's the built up lower pictured above.  The only thing I might want to do is a drop in quad rail, and if I can find a deal on an Eotech or Aimpoint and see what the fuss is about.  I built this to see how inexpensively I could make it so I don't want to go crazy.

Okay, I'm a dumb ass.  I went to the range today, and the rifle was having issues stripping the first round.  Played with it for a bit, finally got it to feed, but not especially reliably.  At some point I noticed the bolt was catching on the body of the BCG rather than on the face.  I figured the buffer must be too long.  Later on I remembered that I used the screw that came with the spacer to make the buffer tube longer.  I found the proper screw that came with the stock, installed that, and now the bolt catch locks on the bolt face.  Just need to get back to the range and test it out again. 

[RobertJames 14]

I got back to the range this afternoon to test the rifle with the correct stock retention screw.  I'm happy to report that the rifle cycles properly now.  While there i sighted in the Nikon P223 that went on it this morning.  

 

Also, the fellow next to me had an Aimpoint and let me look through it.  I see now why everyone likes it so much.

[T Bill 649]

Sounds like a winner RJ, good luck with it.

Glad to hear it was an easy fix!

Given that Luth-AR MBA-1 has an adjustable length of pull, is it still considered NJ legal? How is fixed length stock defined?

[n4p226r 105]

They aren't defined. Like everything it's all messy gray area you won't get a straight answer from

[T Bill 649]

You are adjusting the comb and the length of pull on a stock, not moving the stock, therefore it's GTG.

I just noticed that this thread got bumped.  Just an update on the build, I wasn't at all impressed with the accuracy of the rifle with the barrel from Palmetto.  I got the last stainless heavy fluted 18" barrel from Midwest and installed it on the upper, along with a Rock River brake.  I've only had it out once so far to zero the scope, but so far looks much better.From 6 inches or more at 100 yards to probably more like 2 inches.  When i find the right ammo, take my time and concentrate, it should be even better.  One other issue, it may be over gassed.  When I was shooting to zero the scope, a lot of the brass was landing in front of me, rather than to the side or behind me like usual.  It's got a rifle buffer, I might have to place an order with Heavybuffer.com.  

 

One last thing, I added a Nikon 4-12x P223 scope in place of the Chinese gun show special.

[RobertJames 14]

Finished, Coyotes beware.

 

New barrel

 

 

Rock River brake, disregard the dog hair please.

 

[Junior 14]
