Matt.Cross Posted January 12, 2017 Author Report Posted January 12, 2017 Well, my 416 stainless has arrived, 1 foot in length. It appears there's enough material for possibly 2 heavy buffers, we shall see!

Matt.Cross Posted January 13, 2017 Author Report Posted January 13, 2017 The material is cut and prepared to begin machining in earnest! Saturday morning hopefully...
Matt.Cross Posted January 13, 2017 Author Report Posted January 13, 2017 I have all the needed dimensions and have made up some cutaway models of the old buffer and the new one. They are largely the same profile, but the body of the new one won't be hollow. Old buffer layout.... New buffer layout... Machining hopefully begins Saturday!
survivalshop Posted January 13, 2017 Report Posted January 13, 2017 I was wondering if you were going to use the components from an existing Buffer for the poly bumper on the end & I looked around to see if you can get any internal or that bumper & found this , by Buffer technologies , https://www.galatiinternational.com/product/BTR150.html Thing is , you can get a complete Buffer assembly for less in some places , but , would it be the same material as a Buffer technologies one .z

I figured you would have left it uncut and stuck it out of the chuck on a center and plowed it all in one set up, then cut it off.

Matt.Cross Posted March 7, 2017 Author Report Posted March 7, 2017 Time for an update: I'm an idiot, a total and complete utter moron. Seriously, everyone gets a turn to slap me upside the skull and stomp my balls, believe me I deserve it. My only gas problem is with the quantity occupying space where brain cells should be. I shall explain. I've been tinkering around since adding the LAW Tactical adapter to my rifle, and I noticed that with an empty mag in the rifle, the bolt will lock to the rear (behind the catch) if you withdraw the BCG with the adapter in the open position. While that's normal function for most of you all, since my rifle has been built, the bolt has never locked to the rear on empty. I have always attributed that to two particular factors: 1. I have used (1st Gen) PMAGS exclusively in this build, and they are reputed to be inconsistent in function with various large AR platforms. 2. Both custom BCGs used in the lifetime of this build feature chamfers at the front of the carrier that override the bolt catch. Where the idiocy comes in, is how I've failed to realize the catch is supposed to hold on the face of the BOLT, not the carrier. So I began diagnosing why my carrier wasn't/isn't traveling far enough to the rear to function properly. The short answer is that my buffer is ~1/2" too long, explaining both my short-stroking/bcg overspeed issue, and the failure to lock back on empty. Doh! This became apparent once I compared my buffer measurements with the data mrraley published quite a while ago. Brownells sent me an Armalite AR-15 buffer! It's 5.875" and should measure 5.188"! (Based on this post.) So, while I will still manufacture my stainless heavy buffer, and add my SLR adjustable gas block to the system, I'm first going to modify the existing buffer to the correct length, and see if that corrects my function issues.
Robocop1051 Posted March 7, 2017 Report Posted March 7, 2017 I'm putting a slap in an envelope and mailing it to you. Please open close to your face.

survivalshop Posted March 7, 2017 Report Posted March 7, 2017 Well you deserve it for where the Bolt Catch is supposed Catch the Bolt , but Brownells sent me an AR 15 Rifle Buffer Spring ,when I ordered a 308AR one , sure glade they got the Buffer correct , never take anything for granted in the 308AR world . I discovered it while researching a Thread about Buffer springs & it was a WTF , I should have known better .

I say we get Mrs. Cross hooked up with some triplets for Matt's skull slap. We'll have her watch Mikedaddy's aerobic video to get her "in the mood!" <<<<preview for her
Matt.Cross Posted March 7, 2017 Author Report Posted March 7, 2017 Jon, you really are evil. You need help buddy....
98Z5V Posted March 7, 2017 Report Posted March 7, 2017 Matt, run your buffer length dimensional numbers from Slash's tech data, and use that for cutting your buffer down... http://heavybuffers.com/reference.html

Pat Raley published some numbers too in the link I posted earlier, I had planned to use that, but there's probably no difference.

I can't wait to get home and see if it's going to clear the bolt catch!

Now I have to function test live, and then add the AGB, rinse & repeat.
