    I would like to amend my review of the black nitride BCG. Yes, the product was not staked and there may be a slight bolt/bolt carrier fit issue but after writing this review I emailed 3CR Tactical about the issues. As I purchased this over a year ago I expected to be told that it was too late or nothing at all. Instead, when I checked my email early the next morning I already had a return shipping label from them. I am impressed! It did not come with any specifics about their course of action (fix, replace, refund, etc) but just the fact that they immediately addressed my issue over a year after my purchase was impressive. I would prefer a fixed or replaced product but even a refund would be acceptable. I'll just use it to buy another FROM 3CR Tactical and plan to use them exclusively in the future. Smith and Wesson could learn a few things about customer service from this company. Despite this BCG slipping through I have changed my rating to 5 stars because I am confident that they will make it right.

    It is a high quality BCG but I originally bought it as a backup. I recently decided to build a free floated upper with a Ballistic Advantage mid-length, Odinworks adjustable gas block and tube. No matter what gas setting I used (starting at 1 turn out and progressing to fully out) I still could not get the rifle to cycle properly and ejected brass almost totally foreward, a sign of an undergassed setup. I realigned the gas block more than once, looked for burrs...nothing. It turns out that the gas key not only lacks the advertised staking but it wasn't even tight, the screws needing another 180' turn and the key jiggling a bit front to back. The bolt also has a ring just aft of the extractor that makes a VERY snug fit making hand manipulation of the bolt difficult. Should it be that snug? The stock M&P-15 bolt moves much more freely. 3 stars for poor quality control and what it'll cost to have it staked and inspected.
