Five Star combo

Not sure why the so so reviews for this combo. Bought on a sale and its a fantastic deal. Fit and finish were excellent. Shoots as good as it looks. Just cant beat it if you looking for a budget build combo and its on sale.

<br>They offer it without the muzzle brake and that's a heck of a deal. Cant touch that deal

Five Star Product

by -

I'm rating this 5 stars regardless of what shows up in the star count.

<br>Other reviews say some negative things that I didn't experience. My barrel combo was perfect ! Threads were good , coating and rifling look great. Barrel was dimpled for set screw. Packaged very well. A very positive experience for me. Comes with gas tube pinned to block and block slid on to the barrel to where it starts to get tight and the set screw is snugged to keep it from sliding but, is easily removed for barrel nut installation. Muzzle brake and crush washer are just hand tight. If caught on sale, it's a heck of a deal for a budget build

<br>As always BRAVO to Primary Arms for their FAST shipping and EXCELLENT customer service.

Buy a brand with better QC


The SBN finish is terrible on this thing. Even the muzzle brake has brown runs in it. The barrel fades in and out from runs. Contacting PA to see about swapping.

FYI, this is melonited stainless steel not sbn 4150

An answer to a questions you might have buying this package. Yes, the gas block and muzzle device can be hand loosened so that they can be removed easily prior to installing the barrel on an upper receiver. I was worried myself, but had the tools if needed so I gave it a try.

<br>All in all a nice looking barrel, though the specifications need to be updated for this product. This is a stainless steel barrel with an exterior melonite finish including the threads and at the feed ramps and throat of the barrel. Still a good deal in my book. I'll update the review once I've been able to put some rounds through it.
