MarkCO Posted June 24, 2015 Share Posted June 24, 2015 A great hand-lapped barrel...adding Melonite takes great to amazing in my book. Given the gas port size, I am pretty sure you aren't running an adjustable gas block on any of your Stretch-16 equipped toys. Are you using a low mass BCG and/or reduced springs? I am not running adjustable gas and I am running a JP low mass carrier with a Carbine buffer. But, it will run standard loads with a commercial mass carrier and carbine buffer 100%. There were some smaller sized gas ports on some of the earlier barrels, but they increased the size a tad. Link to comment Share on other sites More sharing options...

MarkCO Posted June 25, 2015 Share Posted June 25, 2015 I can certainly feel the recoil difference and the 30 yard splits are 5-6 inches more spread out on target. Link to comment Share on other sites More sharing options...
Blaster Posted June 27, 2015 Share Posted June 27, 2015 Got a stretch 16 a week ago and had it installed by Gunsmith. I went to the range today and even with Syrac adjustable gas block wide open not getting enough gas. I am using Youngs lightweight bolt carrier and APA brake with standard carbine buffer it does shoot my hand loads sub moa at 100yds. Link to comment Share on other sites More sharing options...
MarkCO Posted June 27, 2015 Share Posted June 27, 2015 Syracs will leak a good bit new. Reduces some over time. Link to comment Share on other sites More sharing options...
Blaster Posted June 28, 2015 Share Posted June 28, 2015 It is a used Syrac. So what are my options?Drill a bigger gas hole in the barrel and use the adjustable gas or I could try a new nortic gas block or any other ideas Link to comment Share on other sites More sharing options...
mpom Posted June 28, 2015 Share Posted June 28, 2015 (edited) Curious if the Syrac is a set screw or clamp model. My guess is set screw. Suspect what MarkCO is implying is that over time, carbon gets deposited that helps seal the GB to gas port interface. Options are shoot some more and see if this happens, go with a good clamp on version, such as SLR, or a tighter fitting set screw model, such as CA. Since there is gas leakage, makes sense to fix that before enlarging the gas port. (another)Mark Edited June 28, 2015 by mpom Link to comment Share on other sites More sharing options...
pcs352 Posted June 28, 2015 Share Posted June 28, 2015 I have one of these barrels and will be assembling it soon. I have an SLR adjustable and was planning on running it but the supplied clamp actually seems to be very well built. The gas port on the barrel is ever so slightly smaller than my other barrels and am inquiring if I can avoid the complexity of adjustable gas and just run the non adjustable gas....I don't load bunny farts and run factory rifle ammo through the long guns.

Advice... It should run just fine with the non-adjustable gas block. The carbon arms gas block is another great option. Link to comment Share on other sites More sharing options...
Therealkoop Posted June 29, 2015 Share Posted June 29, 2015 My standard load is a 55g hornady at 2550 fps. Im using an SLR rifleworks gas block at about 50-60% open with a boomfab carrier and a carbine weight buffer. Ive used the supplied gas block and it was fine. I had an adjustable laying around so I slapped in on there. Link to comment Share on other sites More sharing options...
pcs352 Posted June 29, 2015 Share Posted June 29, 2015 Safe to assume the rifle shot flatter with the reduced gas? If it all shoots the same I'll just run the darn non adjustable...? Link to comment Share on other sites More sharing options...
Therealkoop Posted June 30, 2015 Share Posted June 30, 2015 If you can reduce the gas there is going to be benefit. How much you can actually turn it down is going to depend on a number of factors. Link to comment Share on other sites More sharing options...
Blaster Posted July 6, 2015 Share Posted July 6, 2015 So I finally realized that with my new stretch 16 that 53gvmax going 3100 fps using Vit 133 are less reliable and will not lock bolt back while the same bullet with Vit 140 going 2800fps works great and locks bolt back. Any ideas why? Link to comment Share on other sites More sharing options...

rescue6 Posted July 9, 2015 Share Posted July 9, 2015 I am really thinking about jumping on one of these barrels or the 18" version the intermediate gas feels awesome to shoot. I have shot the 16" version with the whiskey arms aluminum BCG and a JP brake I believe it was like shooting a 10/22 if even that bad. Amazing barrels Link to comment Share on other sites More sharing options...

Amazing barrels The stretch 16 only comes in 16 inches, but if you decide to go for an 18" look at rifle gas instead of intermediate. The Nordic 18" is an excellent option as well.

michael1778 Posted July 10, 2015 Share Posted July 10, 2015 Any current thoughts from Stretch 16 users on what heavier bullets (69 grain and up) it may like more than others? Link to comment Share on other sites More sharing options...

Any ideas why? In addition to slightly more dwell time, using a larger charge of a slower burning powder delays the peak point on the time/pressure curve, increasing the pressure at the gas port.

MarkCO Posted July 10, 2015 Share Posted July 10, 2015 I have yet to try Hornady, but so far, Sierra and Nosler both seem to be happy in both the standard and Melonite barrels. Link to comment Share on other sites More sharing options...
Bullittmcqueen Posted July 10, 2015 Share Posted July 10, 2015 Of my hand loads, mine really like 69grain OTM. I don't have any loads heavier than that. They also really likes Hornady VMaxes. Both will print groups 0.4-0.5 MOA if I do my part. Maybe drew will chime in, I know he likes to run 75-77 grain in his. Link to comment Share on other sites More sharing options...

Mark off the top of your head, what's the weight difference between the Stretch 16 and the Nordic 18"? Only, I hate to use the word complaint, but minor issue I have with the 18" Nordic that I bought from your shop is that it makes the rifle a touch front heavy for my tastes.

MarkCO Posted July 14, 2015 Share Posted July 14, 2015 The standard Stretch 16s are 31 ounces, the fluted are 28 ounces and the Nordic 18 is 38 ounces. Link to comment Share on other sites More sharing options...
