Guntec USA AR-15 Nitride Skeletonized Low Mass Bolt Carrier Group

[Abraham]

Primary Arms is selling these for quite a low price if their list price vs. sale price is accurate.

I've never heard of a Skeletonized bolt carrier group, have you?

Plus, they're having one heck of a sale of 3 different mfgs. of AR15's.

Now, to be sure, I've never heard of the 3 brands, but for the price they may be good entry level market rifles.

They're usually marketed as "light weight" rather than "skeletonized", but several companies offer them. From Bear Creek & AIM Surplus around the $100 mark to Faxon, 2A, Spikes, etc up over $200.

Seems they're usually used with an adjustable gas block.
