Poly Receivers Testing: Prologue

It's been on the to-do list for a long time, but I'm finally able to give some apples to apples comparisons between the New Frontier Armory LW-15 polymer lower and the TN Arms hybrid lower.  Before we get to the thorough run-down with tons of photos I wanted to do a quick first impressions post.

Idea: Lightweight Production AR-15

Update April 2018: Wow, this post is nearly five years old and in that time the concept outlined here has more than become reality!  Five years ago we weren't swimming in sub-10oz free float rails, lightweight components, minimalist optic mounts and more.  At this point it's foolhardy to skimp on the nickel boron bolt group, and as of the time of this update one can procure a lightened NiB group from AIM for all of $99, a product which five years ago would've cost you $300+ from a boutique manufacturer.  Progress is a wonderful thing sometimes, huh?  I've made some changes below to reflect the changing times.

I was talking to a friend and customer of mine recently about putting together a light weight AR-15 that also has the features people really want in a good rifle. Typically the first thing is a chrome lined barrel, followed by replacing the rattle trap M4 stock and chintzy A2 pistol grip. I thought about it a bit and decided on what I would consider a personal baseline for a quality lightweight carbine.



First, apologies to all the folks who have had delays in bluing their firearms. We've gotten really tied up in making improvements to the property and renovating, which has resulted in moving the bluing tanks around several times already. I'm continuing to add odds and ends to the bluing system and metal prep setup as time and budget allow, and hope to have all of it running full tilt "soon".

I've got a lightly used AR-15 on consignment sale, pictures forthcoming.  Here's the spec sheet:

  • Del Ton 1:9" M4 profile barrel, chrome lined 16", standard A2 flash hider
  • YHM Smooth Carbine free float handguard (bottom rail)
  • YHM HK-style flip up sight gas block assembly (rail wraps around it)
  • Spikes Tactical lower, standard M4 stock and buffer
  • Magpul AFG 2, Magpul BAD lever, Brownells Para folding charging handle
  • Comes with a pair of C-products aluminum mags in a dual mag clamp

He's looking for $750 out of it, which is a good value for the feature set.  May include 3 windowed PMAGs with ranger baseplates with the sale.  Price is negotiable though, feel free to email or call.
