G&G Armament M-LOK Handguard for GTW91 Airsoft AEG Rifles

"I second Mark's review. I purchased this based on his recommendations for my Wolf A1 upper. If you're an AR-15 person only, fitting this might be a bit out of your element. If you're an avid AK owner, this might take you an hour or two to fit perfectly. Most of the fit/grind spots are at the base of the lower hard into the upper retention spring. Rounding them out, no squares in circles. Another cut is to remove some of the lower slide lock to allow a farther upper/lower lock and then slide the lower back into position. The upper pin alignment took some time to get right as I choose to grind the upper pin holes down on both sides about a 1/8. I ended up using the original Wolf handguard pin. Pin lock up is snug afterwards. I can hold the handguard and shake with no movement. If anyone wants pics, hit me up on reddit: u/thefuturehero. You'll need a Dremel, metal cutting disc, file, and grinding bit (1/8). Overall, I wouldn't run over it with a car, but as far as an aluminum handguard for a upper really has no other positions, it's top tier.

"I Looked Everywhere for a Replacement HG for a Actual Wolf T91 556 Upper Receiver and I was Actually Able to Fit One of These Handguards to Mine. It Took a Bit of Brainstorming, As this Air Soft Version HG was a Bit on the Snug Side Fitting the Rear Ferrule on the Wolf T91 (Too Big). A Few Hours of Slow Fitting with a Dremel Tool and I Made It Work. Now I Am the Proud Owner of a Wolf T91 with a Custom Fitted MLok Rail on it.
