Troublesome but good. - Luth-AR Palm Handguard

Item was delayed due to supply availability. OP shipped as soon as it was available. This is a clamp on style handguard. I installed on a 450 bushmaster and it moved after a few rounds. Email communication with Luth was prompt and a new barrel nut with more aggressive knurling was shipped within a few days. New nut bites into the hanguard far better than original. Finish is great. Rail is ever so slightly lower than Anderson Upper. Not a big deal as a front sight should adjust to appropriate height. Feels great and lightweight.
