Enhanced Buffer Tube Kit - AR15 | Trinity Force

Enhanced Buffer Tube Kit - AR15 | Trinity Force

$49.99 $36.00

Torque Precision has added this Exceptional Value Enhanced Buffer Tube Kit made by Trinity Force to our recommended Value Line Defense products because of it's excellent cost to quality benefit.  Although this buffer tube kit is inexpensive, this is not a cheap buffer tube kit. This is a high-quality buffer tube kit that also comes with Trinity Force's Lifetime Warranty.  

This Enhanced AR Receiver Extention Kit is constructed from aircraft grade aluminum with rolled threading. The buffer tube has been hard coat anodized for maximum corrosion and wear resistance. A enhanced flat wire buffer spring and 3oz carbine buffer are included as well as a steel castle nut and lower receiver endplate with QD mount.

This assembly kit will fit on all Mil-Spec AR 15 lower receivers. It is also compatible with some AR308/AR10 rifles but requires a modified buffer and spring for proper operation.

We regret to inform you that PayPal has shut down our account because
non-ffl firearms accessories violate their acceptable use terms.
Earlier in the year STRIPE Credit Card Processing also shut down on us
for the same reason. Our webstore is compatable with one last
credit card processing vendor. It is a matter of time
before our current and last optional vendor realizes we are violating their acceptable use terms by
the nature of our business. We are currently working
to rebuild this website with an alternative host so we can utilize
other credit card processing vendors. At anytime our current
credit card processing vendor can shut us down, rendering us unable to do business on this website.
If such a case happens, it will be impossible for you to purchase from
Torque Precision, until we launch our new website. This could mean
we may be down for a few weeks. We hope to launch our new site by August 1st.
