If the gun has a thumbhole stock then it will be a rifle length buffer. If this is the case an adjustable gas block might be best option.

Also a carbine buffer in said rifle tube will result in a beat up buffer tower.

It the Spear Mags stock, so from what you're saying Digit, the Spikes tactical ST-2 buffer won't work in my AR cos it a rifle length buffer tube??

If i had of said rifle length, it would have been a *face-palm* moment lol

Still might be yet.

Just had a look mine is the rifle length buffer, F#*K sake! Might have to cancel that order and go for the adj GB...

You're SOL mate. Adjustable it is. Seriously though I run an H3 in one of my carbines and it really makes fuck all difference.

Order 2 low profile ones. I'd be keen on one.

The T2 buffer is lighter than a rifle buffer anyway.

Most adjustable gas blocks bought by themselves can be bought from brownalls with no paperwork at either end,and if it does get stopped at nz customs a email from your local arms office will get it released.
I like the JP low profile.

Or just turn your curent gas block into one, it's not hard.

I am pretty sure if it goes over $100US you will need paperwork.

Did you buy through us as I have two T2's going out this morning. Let me know who you are (PM) so I can cancel your order asap.

I was under the impression that the HPT process was basically subjecting the bolt to a proof test, which also has the effect of potentially shortening the overall life of the bolt by quite a margin. I read that the US army found that bolts (even HPT/MPI tested) will begin to crack at 5,000 rounds, and will generally break at 10,000 rounds.

If bolts tend to let go at the same time, I'm not sure if the benefits of HPT stack up, but interested in others views.

All colt bolts as far as I know are tested and marked MPI. Many others do not or batch test only.

Personally when I have a new boiler (or any pressure vessel) a 1.5x or 2x overload test is the normal for insurance / QA purposes and gives some assurance that there is no serious but hidden unique defect. So no it doesnt or should not shorten the life for a component as a one off when new.

Army, well apparently they replace the bolt at 7500rounds or so as they do a lot of auto fire which really stresses the bolt. Again from what I can read 20,000 rounds or 2 or 3 barrels in a "retail" environment ie you and I is quite typical. Bolts are however really cheap and getting a matched bolt and barrel seems to be the best option for accuracy and long life.

While you are right,most gas blocks are under that number-ESP if you by on sale of have a discount code
