    Well, I got a package from Lawton Machine today from the nice man in brown!! I was chambering a barrel when they came in and had to shut things down just to get a look at these new toys!!!

    In the package were two M7000 receivers and a barrel I ordered for myself which was a 270, 1-9 6 groove with 8 of Barneys heavy flutes.

    First off, here is a pic of the two receivers, both M7000 which is the option for a drop in fit for the Rem 700 receiver. They are not a direct clone though!!!

    [​IMG]

    You can see one receiver has the standard bolt and the other has the optional fluted bolt. Also, the one receiver has a 20 MOA steel rail fitted to it already. All I can say about the rail is that it is VERY stout!!! It is also very nicely finished and is attached by four attachment bolts. I think they are 8-40s but I would have to check again to make sure.

    These receivers use all the same accessary items as the Rem 700 such as triggers, floorplates and stocks but there are differences for sure. You will notice that the ejection window is much narrower then the Rem 700 which results in a MUCH stiffer receiver design. The Lawton receivers also has a full diameter for both the scope rail base attachement locations. Unlike the Rem 700 which has a thinned rear support area. Again, much stiffer and dramatically improved consistancy. How many rails fit perfectly on the Rem 700 receivers??? NONE!!!

    There are also some other slight differences that most would never really notice. The bolts measure 0.702" in diameter roughly. This is compared to a Rem factory bolt that is on average around 0.695" in diameter. This is not much and does not effect strength but it does effect bolt fit to receiver and the Lawtons are MUCH tighter then the Rem 700 bolt to receiver fits.

    Also, the bolt lugs on the Lawton are roughly 25 to 30 thou longer then a factory Rem 700 which does add to the strength of the receiver over that of a factory Rem 700.

    The Lawton receivers also use a Sako style bolt stop which is very nicely machined into the off bolt side of the receiver. This may require some minor inletting for some Rem 700 stocks but this is not a problem at all, easy to do.

    Another feature I like is the extractor which is positioned on the forward portion of the right bolt lug. It is similiar in design to the standard Sako extractor but not as large. It actually looks like the Superior Shooting systems 2000 extractor but I am not sure.

    What I really like about it is that it is positioned to eject the cases straight out level with the axis of the receiver. Unlike a traditional Sako extractor which is positioned above the lug that throws the cases up as they are ejected.

    Anyone that has used a Sako extractor with a scope that has large target turrets have seen the brass smears on your windage turret and at times this can cause ejection issues.

    There will never be a problem with these receivers and this extractor design.

    Here is a pic of the left side engraving and it is done very nicely. Its funny, in talking with Barney, he told me his receivers were sort of a working mans custom action and as such not to expect the finish of say a BAT or Nesika. While the finish may be a bit heavier matte, I see no real difference. Very impressed with the fit and finish.

    BUT, now it was time to see how they stacked up as far as receiver sqaureness goes. Keep in mind, these are standard receivers, not the BR spec receivers from Lawton. TO check for receiver squareness, I like to clean a receiver totally, getting rid of any oils, grease or chips from machining. Then I set the receiver with its bolt in locked position, up so it is pointing vertical, position the recoil lug(included by the way)on the receiver face. I then take my 0.0001" depth micrometer and take four measurements across the bolt face. One at 12:00, 3:00, 6:00 and 9:00. To do this properly I pull the striker assembly and the plunger ejector. Just want a stripped bolt body in the receiver.

    For comparision sake, I took three out of the box factory Rem 700 receivers, one Sako TRG-S receiver, two Win M70s(one CRF, one push feed), one BAT 2"x10" match receiver and two Nesika Bay model M receivers.

    Set them all up the same way using match grade recoil lugs on all that needed them(all except the Win and BAT receivers). Took the same four measurements on all of the receivers. TO figure how square the receiver is you simply take the total variation from the four measurements.

    Taking this measurement tells you the relation ship between the following surfaces and their squareness to the axis of the receiver: Forward recoil lug surface, rear recoil lug surface, receiver face, receiver bolt lug locking recess, bolt lug locking surface and the bolt face.

    All of these surfaces have to contact each other to come up with the total squareness of the receiver system. It does not take much variation to add up quickly!!!

    I will be totally honest here. What I found with the custom receivers and the factory receivers really suprised me!!! Especially from the very expensive custom receivers.

    I will list the receivers as most variation to least amount and their variation beside each receiver.

    Win M70 CRF............0.0028"
    Rem 700................0.0019"
    Win M70 PF.............0.0018"
    Rem 700................0.0014"
    Sako TRG-S.............0.0010"
    Rem 700................0.0008"
    Nesika Bay.............0.0006"
    Lawton M7000...........0.0005"
    Nesika Bay.............0.0004"
    Lawton M7000...........0.0004"
    BAT 10"................0.0003"

    Now if you notice the first five factory receivers are all between one and three thou in variation across the bolt face. Only one factory receiver, one of the Rem 700s got under the 1 thou variation range, not very impressive.

    All of the custom receivers were right at or under half of a thou in variation across the bolt face. To my suprise, the most expensive receivers, by far, the Nesikas were on the top of the pile. Even more impressive was that the "econo" model of the Lawton, the M7000 was as good or better then the Nesika Bay in receiver squareness and only 1 and 2 "ten-thousandths" of an inch behind the huge BAT receiver.

    Now, I have used alot of Nesika receivers and I have yet to have one that did not shoot EXTREMELY well at any range. What I see from this test is that the Lawtons should offer just as true of a platform to fire off from out of the box as a Nesika Bay receiver. Only for 1/2 the price!!!

    The big BAT was not a suprise to me being the best of the test receivers as it is a full blown BR receiver. That said, it is not much better then the Lawtons and remember I have yet to get the Lawton M7500 BR receiver in to put the mic to. I suspect I will again, not be unhappy with the findings.

    Now the test for these receivers is to get barrels on them and get some bullets in the air. Thats really the only test that counts!! That will be coming soon. The barrel I ordered is my personal test barrel that I will fit to the M7500 BR receiver I have coming from Lawton. Barney tells me its pretty much ready to ship so that should not be long.

    [​IMG]

    Here is a pic of the unique round flutes that Barney mills into the barrel. There are eight of them on this barrel which is a 1-9 6 groove to test the 195 gr ULD RBBT Wildcat bullets.

    More testing to come but so far, it appears that the Lawton M7000 repeating receiver will measure up to the BATs and Nesika Bay receivers. So far very impressed!!!

    Would you be able to post some pictures that show the extractor setup?

    What is the scope base hole configuration? Remington or something else?

    Thanks

    Kirby thanks for the detailed description pics and measurements. They look like a great action for the money. The 20 MOA scope bases look great especially for the price. I love my savages but I might have to buck down a buy a lawton /ubbthreads/images/graemlins/smile.gif

    AWESOME story and pics. I am very impressed with the variations. I sounds like Lawton will be getting lots of buisness, I am glad I ordered one. I have been hearing and reading that they are excellent actions and close to BAT quality. Your test, so far, has proved that the Lawton actions are close to BAT quality. They look good too!!! When I read the title of the post, I thought Kirby had already received my Lawton M8000 and was trying to tease me, LOL!!!. Kirby, I know you have already ordered my receiver from Barney, can you have my Bolt Fluted, or is too late. Great post with excellent info.

    Hey Kirby,
    Can you post this on a couple other sites?
    I didn't want them to send you that ugly barrel but they got it out before I could get it hid.
    I'm glad you like the 7000s. I'll get the 7500 done real soon now.

    Wildcat,

    The M8000 comes with a spiral fluted bolt I believe. If I am wrong on this I am sure Scott will straighten me out.

    Remember I am comparing the M7000 receiver to the top end receivers in the world in the Nesika and BAT receivers. I was a bit suprised the BAT and Nesikas did not mic out more square then they were but again, I have never had a Nesika shoot anything but GREAT. That is a good sign for the Lawtons in my opinion.

    The M7000 is the direct replacement to the Rem 700 receiver. The M7500 is much more on line with the Nesika Bay Model M receiver. They have a stretched thread engagement section, longer bolt head and built to tighter tolerances. I am very optomistic to see what the Lawton BR M7500 receiver has to offer comparision wise. I would bet it is on par with the BAT at least!!!

    The M8000 should also be on this same line of quality.

    themachinest,

    Have a couple questions for you. The barrel blank measures roughly 31.5". This is a 30" finish length blank, do I cut the muzzle back to get it to the correct length of the breech end? Just want to know how much of the muzzle needs to be cut off to get to good barrel after the lapping process?

    Where else do you want it posted?

    Also, what is wrong with that barrel or different from the other barrels?

    Am I correct in that the M8000 comes standard with a fluted bolt?

    Looking forward to that M7500!!

    Lerning,

    Here is a pic of the extractor on the M7000 bolt.

    [​IMG]

    The scope base is unique to the Lawton receiver. You will need to get one from them but from what I see they are extremely high quality and much less expensive then say a NF or Badger Ord rail base. A steal in my opinion. They have to front 8-40 screws and two rear 8-40s holding the rail base down solidly!

    Wow, with tolerances this close to the BAT action I expect to see great things when you put the barrel on Kirby.

    It is a real pity that we do not have a UK importer of these actions, they look almost too good to be true (if you'll pardon the pun)

    It is a nice touch to have horizontal extraction as opposed to the Sako upward lift, which has caused many a dent in my own thin walled cases.

    Excellent and informative post Mr Allen (again) /ubbthreads/images/graemlins/grin.gif

    Kirby,
    You will need to cut at least 1 inch off the muzzle, that's normal. If you want it to finnish at 30", you can cut more from the muzzle or the chamber end. You will want to pay attention to the flutes so you don't run out of room for a brake if you want one. Also, there isn't a blamed thing different about that barrel compared to others we put out, I was just razzing you.
    Yes the bolts for the 8000s come standard with flutes. You can get them either way, just say so when you order. The 8000 actions are on par with the 7000 actions in that they are not BR actions. They are ment to be users, that said, there's nothing wrong with making a good user.


    I don't jerk the trigger, I just squeeze it faster some times.

    I have # 31 on the Lawton 7500 and it is really tight. That is my only gripe, it is too tight in the bolt area and hangs up closing. Nothing a little polishing will not soon take care of.

    Had it about two months on a 6 BR DS (ack imp) and will definitely buy another.

    BH,
    If you want to send it back, I'll lap it in for you. That sn is before we started lapping in the bolts. Now all complete recievers are lapped.
