Horsemen Posted November 6, 2011 Report Posted November 6, 2011 Any of you using the TRX with an adjustable .964 gas block? If so which one or ones fit.
Horsemen Posted November 6, 2011 Author Report Posted November 6, 2011 Brain fart <lmao> i do mean .936
98Z5V Posted November 6, 2011 Report Posted November 6, 2011 The only one I know for sure that will clear is the PRI. Their .936 cleared a TRX on an AR-15 build I did, and I think that TRX is ever-so-slightly slimmer in diameter than the .308 TRX. It'll go. Comes with it's own gas tube, but you might have to call them to get the correct length:http://www.precisionreflex.com/Detail.aspx?PROD=186815&CAT=4274
Horsemen Posted November 7, 2011 Author Report Posted November 7, 2011 The PRI in 308, they have 2 listed. Has a straight 15.65" gas tube. The outher one is listed with a 15.495" tube.
98Z5V Posted November 14, 2011 Report Posted November 14, 2011 Call them up, brother - they're great to talk to, and they'll definitely guide you on the right direction on which one you need for your build. <thumbsup>
Horsemen Posted November 14, 2011 Author Report Posted November 14, 2011 Called PRI, the DPMS barrel has the gas block placement, the same as a AR15. So I got the shorter gas tube. Parts to be here First of next week. <thumbsup>
Horsemen Posted December 3, 2011 Author Report Posted December 3, 2011 Well is dosn't fit. <dontknow> To make it fit the screw boss will need to come off. I think I will make one that will fit with the adjustment in the front.
98Z5V Posted December 4, 2011 Report Posted December 4, 2011 Post up some pics of the interference, man, so I can take a look at where it's hitting. This might be easier than you think. <thumbsup>I "massaged" a YHM Specter gas block to fit under a DD RIS II rail, so this might not be too bad.
Robocop1051 Posted December 4, 2011 Report Posted December 4, 2011 I had to "persuade" my DD rail to fit with a AA Piston kit.
Horsemen Posted December 26, 2011 Author Report Posted December 26, 2011 I finally got sometime and started the gas block. I could have use the belt sander on the PRI block and made it fit. But I have the tools to make one. So why not. The first picture shows the problem. Now to the second problem. The PRI block with the screw bottomed out has a "lot" of leakage. After testing the one that I roughed out, the leakage is noticeably less. I may try a smaller gas hole around .120 ish, on another one, just to see if I can get even less leakage. The second picture is the roughed out block. And the third one is the block mounted on the barrel. Next week, if time permitting we will mount it to the rotary table for shaping. Its looking like the PRI block will be in need of a new home, less the gas tube. <thumbsup> O I frogot, the block after shaping will be the same height as the PRI block. I also plan on a .750 block also.
Robocop1051 Posted December 26, 2011 Report Posted December 26, 2011 My GAWD!!! Look at the size of that freakin barrel. I'm having some inadequacy issues. Your rifle is challenging my manhood.... And it's winning :-[
Horsemen Posted January 30, 2012 Author Report Posted January 30, 2012 I finally got it done. Now the gas block fits <thumbsup>
unforgiven Posted January 30, 2012 Report Posted January 30, 2012 Welcome from Indiana brother Horsemen,great job looks great. <thumbsup>
98Z5V Posted January 30, 2012 Report Posted January 30, 2012 You did an incredible job on that gas block - that's badass. <thumbsup>
Matt.Cross Posted January 30, 2012 Report Posted January 30, 2012 I like that unangled gas tube, that's sweet!
Jgun Posted January 30, 2012 Report Posted January 30, 2012 Nice looking gas block. Did you profile that with a CNC? If you've got access to that, you might want to consider running off a few, not that you're going to make much on them, but, you never know what it could lead to.
Horsemen Posted January 31, 2012 Author Report Posted January 31, 2012 Jgun. The machines i have are all manual. there are some ideas that I'm kicking around about making them better, like getting 0 leakage, when adjusted all the way closed. I started this project with the Idea of making more. Perhaps summer I will have them perfected. The next one will be a .750. if that comes out like i expect there will be another .936. as far as CNC. I do have limited access. That may come into play if the next one comes out as planed.
Jgun Posted February 1, 2012 Report Posted February 1, 2012 Does that mean you put it on a .936" mandrel in a rotary table? Or did you use form tools?
Horsemen Posted February 1, 2012 Author Report Posted February 1, 2012 Jgun, I made a rotory table top jig. later today i will try to post a picture.
Horsemen Posted February 6, 2012 Author Report Posted February 6, 2012 Sorry i got tied up. Here is the jig plate.here is the jig.After every thing was fitted, I looked all over for a bipod mount. Troy only offers a rail, no mount. So back to the drafting table. Simple and light. The old Harris bipod fits well. Shooting it will be soon, Need that bolt group, and scope mount.
