Will be fun when the gas system works!

Nice looking rifle

I'm about to build one almost like it. What is your tube issues? Where is your gas port?
Thanks

Gas block is at the pistol position. Apparently there are two pistol gas tube lengths ... 6.7" and 7.5" The tp555 gas block needs a 6.7" block. Even than one has to remove 7/8 or an inch of the distal end (end going into the block).

I bought my first tube from Del-Ton as it was the only place I could find one listed as in stock. tp555 suggested I try M1S as a source. (I had not thought to look there.)

So I've ordered one from them ... hope it gets in soon!

note
 

keep us updated

Tubes is going out in todays mail.I have specs for my gas block tubes. Max length of 5.750" from tip to gas block shoulder that touches the barrel.You can cut an inch off the tube and adjust the length.I made barrels for Tromix that had the gas block area 3/16" farther away.So there is some slack.At the 5.750" spec tube is about .085" from touching the inside of the key.The tube goes into the key over .8" deep.

Hooraaaaahhhhh!!!!!

tp555 delivers the one that REALLY works!

125 gr NBTs; 16.5 gr WW296; WSR load cycles properly and bolt hold-open works too!

Just checked for cycling. Will check accuracy when the weather is a bit better and I can find the box of loaded ammo.

(Used a Stag lower with an RRA two stage NM trigger. Need also to check the BRO lower with the Bill Springfield single stage trigger ... but that won't be a test of cycling I think. More a test of hammer fall.)

THANK YOU, Sir!

Looks great. I am also building a similar setup and have been in contact with TP555. I am going to order a 16" barrel in chromoly (black) threaded as yours is with the 3 position gas block in the pistol length. I am waiting for pricing. What profile is your barrel? How long was the turn around time from when you ordered till you received everything. I hope he can supply the tube for me as well to ease hunting for parts. Also, whose flash hider did you install. It looks like a YHM.

My build is going to be on my R-15 to use as a hog/deer gun.

I hope his gas block will slide inside the fore end. I want to keep the all camo look. If I don't use a flash hider, I may just use a thread protector.

Are you able to chrono your loads. I am curios what speeds to expect from a 16" barrel from 125's and 150's. any plans to run subsonic?

Thanks

I knew I'd get a smile out of him eventually.

Now you know why I refer them all to you:smile:
